->''"My name is Ennis... Just Ennis."''
-->-- ''LightNovel/{{Baccano}}''

The character or characters go by a single name, with no family/clan/whatever identifier. Unlike NoNameGiven, it's not that their full name is never made known to the viewer. The full name simply does not exist. Cher is an oft-cited example.

TruthInTelevision for [[OlderThanDirt most of history]]. [[TheMagnificent Bynames]], epithets, and family names were used only when necessary to distinguish between people with the same name. In much of the world, having multiple names is a relatively recent invention.

Sometimes appears in translations when it didn't in the original, such ComicStrip/BeetleBailey being called just "Masi" in Finnish. This could be seen as going under OnlyKnownByTheirNickname, but not when the character is addressed both on a FirstNameBasis and LastNameBasis in the original and the translation uses the one name for both.

Contrast IHaveManyNames. Compare EveryoneCallsHimBarkeep for an extreme example.

Not to be confused with the similar-sounding FirstNameBasis or OnlyKnownByTheirNickname.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* The entire cast of ''{{Simoun}}'' is from a culture that gives Only One Name.
* ''Manga/{{Yu Gi Oh 5Ds}}'' never gives last names to Leo, Luna, Bruno, Lazar, any of the Emperors of Illiaster. Which is actually very strange, because most characters are given them.
* Caren, Coco, Noel, Sara and, actually, ''most'' characters of ''MermaidMelodyPichiPichiPitch'' have only one name; the exceptions are the [[PowerTrio main trio]] and the men in their lives (although, in the manga, Hamasaki has only one name too).
* In ''Manga/AzumangaDaioh'', Sakaki is only known by that name, to the extent that, in the first episode, when everybody is introduced by their full name (including Osaka), she's simply introduced as "Sakaki-san, a.k.a. Sakaki-san".
** Kagura gets this treatment too. Whether Kaorin has a family name depends on what part of {{fanon}} you want to believe. Chihiro doesn't even get that much (and is very secondary.)
*** The DVD cases seem to suggest that this is less OnlyOneName and more LastNameBasis, at least as far as Sakaki and Kagura are concerned.
* [[BlindSeer Rezo the Red Priest]] of ''{{Slayers}}'', only known by his title. His great-grandson Zelgadis was this initially; however, his surname (Graywords) got mentioned in an interview with the creator, and it eventually gets mentioned several times. Also played straight with villains and minor characters.
* [[TheStoic Amon]] of ''Anime/WitchHunterRobin'', and that might just be his CodeName, as he's usually [[BadassLongcoat described]] to the cast rather than [[NoNameGiven named]].
* Delilah and Liddell of ''Manga/KagihimeMonogatari''.
* ''LightNovel/HaruhiSuzumiya''
** Side characters always only have one name, or [[NoNameGiven no name at all]]. If a character's full name is given, that character is supernatural in some way. Notably, we never learn [[{{Narrator}} Kyon]]'s name at all. It's just a nickname his aunt gave him that his little sister spread around, [[OnlyKnownByTheirNickname and now everyone calls him that]].
* Van in ''Anime/GunXSword'' is just Van. Instead of a surname he has a number of nicknames, some compliments and some not (his favorite is "Van of the Dawn"). In point of fact, there are only six characters with surnames given through the entire series: William Will Wo, Ray and Joshua Lundgren, Carul Mendoza (she prefers to go by [=Carmen99=]), and Michael and Wendy Garret.
* In ''Manga/{{Naruto}}'', Sai has no family name, since even his given name is nothing more than an alias, while Team 7's temporary leader after the TimeSkip is only known by his codenames "Yamato" and "Tenzo". [[WoobieDestroyerOfWorlds Gaara]] and his siblings Kankuro and Temari don't seen to have surnames either; some people use "of the Sand/Sabaku no -" like a surname (though that's really just an epithet which applies solely to Gaara), or just call them [[FanNickname the Sand Siblings]].
** In fact, it's easier to list the non-Leaf village ninja that ''do'' have last names; the Seven Swordsmen of the Mist minus Chojuro, Team Dosu, [[AuthorityEqualsAsskicking Mizukage]] Mei Terumi, Suigetsu Hozuki, [[SealedInAPersonShapedCan Two-Tails jinchuuriki]] Yugito Nii, and bit-character [[http://naruto.wikia.com/wiki/Shibito_Azuma Shibito Azuma]]. Even in the Leaf Village, a number of characters go without surnames; the Sannin (Tsunade does ''not'' use her grandfather's clan name of "Senju"), and Tenten.
** Given that everyone in ''Naruto'' is on a FirstNameBasis, even to the point of using {{Honorifics}} like ''-sensei'' and ''-sama'' with first names, it's possible a lot of characters just haven't had their last names revealed (it took 200 chapters for Danzo's last name of Shimura to be revealed, and we didn't find out that Dan's last name was Kato until '''374''' chapters after we first saw him). Still, it seems that Leaf and Mist are the only two villages where surnames are commonly used.
* Pretty much EVERY character in ''Manga/HokutoNoKen'' have no last name. If you can consider most of the names REAL.
* Hevn and Makubex in ''GetBackers''. With the latter, it actually becomes something of a plot point that he doesn't know what his given name is--or if he ever even had one in the first place. All they know is that he was found in a bag with "Makube" printed on it; later, people that knew and admired his skills added an 'x' to express the unknown. Thus, Makubex.
* The Leafe Knights from ''{{Pretear}}'' have an excuse of not being from our world, but even outside their MagicalLand they don't seem to use last names. No one in human world seems to care.
* A good number of {{Artificial Human}}s in ''MagicalGirlLyricalNanoha'', such as Signum, and Vita. Vivio used to be an example, until Nanoha officially adopted her and she received the Takamachi name.
** The {{Familiar}}s like Arf and [[SpellMyNameWithAnS Rynith]] have only one name. The majority of the fandom believe that Lieselotte and Liesearia have two names, but their shorten names, Lotte and Aria as well as the collective name Liese are just nicknames.
** After ''[=StrikerS=]'', four of the [[{{Cyborg}} Numbers]] were adopted by [[spoiler:Genya Nakajima]] and took his family name, with the rest remaining with only one name.
* Kyu from ''TanteiGakuenQ'' never has a last name mentioned in the show (Its likely to be Renjou, however,) neither does his mother. Supposedly, this is because the identity of his father is a secret; however one does think that if he has his father's last name, this would make it pretty NON-secret and thus he must have a DIFFERENT one that he and his mother actually use.
* Absolutely no one had a last name in the beginning of ''Anime/TengenToppaGurrenLagann''. Apparently surnames were a practice abandoned AfterTheEnd. They do get them after the TimeSkip, though, taking them from their villages' names (Kittan Bachika, Rossiu Adai, Yoko Littner, Nia Teppelin).
** Simon, however, remains as just Simon, possibly because either he didn't like his village, or because even without a surname, everyone knows what Simon they're talking about. Like-wise Kamina.
* Poked at at the end of the manga ''EerieQueerie''. In the omake afterwards the two characters decide that they can finally call each other by their given names, only for Hasanuma's name to be *bleeped* out. And thus he remains with only one name.
* Ennis is the only character with no last name in ''LightNovel/{{Baccano}}!'' she being an [[OurHomunculiAreDifferent Homunculus]] made by Szilard Quates.
** The light novels reveal that she eventually does acquire a last name after a number of decades: [[spoiler:[[HappilyMarried Prochainezo]]]]
* No one in ''HidamariSketch'' has two names.
* Kino of ''LightNovel/KinosJourney''. It's not even their original name, but one adopted from another traveler.
* Several denizens of the Magic World in ''Manga/MahouSenseiNegima'', including every one of the [[PunchClockVillain Canis Niger bounty hunters]] and [[spoiler:Fate, whose real name is Tertium]].
* Black Star from ''Manga/SoulEater''. Apparently, every one in his family (the Star Clan) is only named by a colour and "Star". Even though it could be as though his first name is "Black" and his last name is "Star", this is unlikely seeing as nobody ever calls him "Black", or "Star".
** Also, Death the Kid, being a younger Death.
** Strangely, Crona seems to have just that name as well, even though his/her mother had the last name "Gorgon".
* Everyone in ''Anime/PrincessTutu''. Mytho, Ahiru/Duck/[[GratuitousGerman Ente]], and Rue probably doesn't even ''have'' last names, and the characters whose last names ''are'' known (Cat, Drosselmeyer) aren't given ''first'' names.
** Well, [[spoiler:on Drosselmeyer's grave]] we're given "D.D. Drosselmeyer", so we know his name starts with a D...but that's the closest we ever get to a full name on the show.
* In ''AxisPowersHetalia'' most [[AnthropomorphicPersonification nations]] have human names which are not entirely canon (they're never used in the actual manga/anime or by the creator except for two dubious instances in strips, and they originated from saved text from the author's deleted site blog), but very popular in the fandom because many fans are uncomfortable with using the actual country names. The human names are all composed of first, last, and sometimes middle names except for Germany, known only as Ludwig. Most fans borrow his 'brother' Prussia's surname Beilschmidt.
** Some fan names are mistaken for (the semi-) canon by the fans. For example, Yekaterina "Kastyusha" Braginskaya (which was inspired by Russia and by Yekaterina being a popular Slavic girls' name), is often used by fanfic authors. As well, "Matthias Køhler", a fan-name for Denmark, was mistaken by fans as an actual name after it was posted on ''our'' TV Tropes character page for Hetalia. Officially, all the characters go by their nations' popular names, which are almost all OnlyOneName (i.e. England, America, Canada, Denmark, Ukraine, France, Germany, Italy (for ''both'' Italies), China, Japan, etc.).
** At one point the human names were considered to be somewhat canon, as Himaruya answered a fan question and said that they would find out one day why Ludwig didn't have a surname. But as it was an old question on the deleted blog and the names have not been ever officially used, it remains unknown if that "significance" will ever come to light.
* All of the demons in ''ChronoCrusade'' have only one name--Chrono, Aion, Shader, etc. However, it seems most of them have at least one title tacked on, like "The Sinner" or "The Slayer of a Hundred".
* In the ''Anime/SonicTheHedgehog'' OVA, Sara's last name is never given. Her dad is only referred to as [[EveryoneCallsHimBarkeep Mr. President]].
* The [[HumanAlien aliens]] in ''Niea_7'' only appear to have one name, including the show's eponymous character.
* Most characters in ''OnePiece'', especially minor ones, but also some main characters (Nami, Usopp, Sanji, and Brook) have only one name.
** This becomes jarring when the main characters get wanted posters. Monkey D. Luffy, Roronoa Zoro, Nico Robin, Tony Tony Chopper, and... just Nami? It's as if the Marines pick and choose when to find out their full names.
*** Possibly justified for Nami and Sanji being orphans and all, Usopp was given a bounty under his Sogeking alias and Franky's real name is Cutty Flam.
*** Notorious characters who fall under this trope almost always get an impressive epithet (Cat Burglar Nami, Black Leg Sanji, Red Haired Shanks), although...not usually on their wanted posters.
* ''KiddyGrade'': "What's my name?" "Éclair." "Éclair WHAT??" "Just Éclair." Also applies to the entire cast (though Alv seems to get a surname in the spin-off).
* The title character of ''EurekaSeven''. In the AlternateUniverse [[TheMovie Movie]] one screen says her last name (which she probably had because she spent a good part of her life among the general populace) is "Zita".
** Given that "Zita" means "seven" in English, Eureka Zita = Eureka Seven
* Most of the characters in ''Manga/DragonBall'' only have one name. Basically the only ones that have full names are Son Goku, Bulma Briefs, and their relatives.
* ''Manga/ElfenLied'' has this with its entire cast, with the two exceptions of Mariko Kurama, Yuu Kakuzawa and Anna Kakuzawa.
* Yuki in ''{{SEX}}'', because of his IdentityAmnesia. His DistaffCounterpart, the female assassin Yuki also goes by only one name (and is often referred to as Female Yuki).
* Most of the cyborgs of ''GunslingerGirl'' have only one name, a deliberate choice on the part of [[TheHandler their handlers]] due to the difficulty some of them have in making the girls into killers, but have no wish to easily dismiss them because of such. Jose and Hilshire gave their cyborgs female names (Henrietta and Triela, respectively) and, despite initial discomfort, try to connect to them on personal levels, while other handlers give their cyborgs are given boy's names (Rico, Petrushka and Claes) to help them keep some emotional distance and make their reconciling with what they're doing a bit easier.
** One exception to this is Elsa De Sica who, despite having a full and non gender-blended name, has less behind it. Her handler, Lauro, simply had to call her something and the first thing that came to his head when he stopped to think about it was the name of the park he was walking through at the time. Elsa's name is precious to ''her'' - in addition to being a "gift" from Lauro, it's the keystone that maintains her very sense of self and describes her as a person, not a latterday golem, whose struggles have meaning. The realization that that self is merely a dismissive and indifferent token destroys her [[spoiler: and is one of the reasons why she snaps ''[[MurderSuicide fatally]]'' on Lauro.]]
** Petrushka doesn't quite fit that criteria as Alessandro didn't give too much thought in naming her, but he easily accepted her identity as a cyborg with little problems, thanks in part to his rather flexible morals and views carried over from his previous duties as a spy, and has grown to care for her to the point that they're romantically involved.
* Almost everybody in ''QueensBlade'' minus Leina Vance, her sisters, and Annelotte Kreuz from the sequel ''Queen's Blade Rebellion''.
* Tetsu from ''Anime/CardfightVanguard'' has nothing other than that name listed in [=Team AL4's=] roster.
* In ''Manga/YuYuHakusho'', demons apparently don't have surnames (with one notable exception being Saotome Jorge/George, Koenma's blue ogre). Even if they have more than one name, it tends to be a title i.e. "Jaganshi" Hiei and "Yoko" Kurama (except for the English dub, in which Yoko is his "true" name). For the Uraotogi team, the two names are their name and an adjective that describes their corruption, rather than being a surname and given name, i.e. Kuro Momotaro = Black Momotaro, and Ura Urashima = Reverse Urashima (though Ura Urashima later reveals that his, and likely the rest of his teammate's names are mere pseudonyms in an attempt to deceive others into believing they are demonic reincarnations of folk heroes).
* ''LightNovel/ShakuganNoShana'':
** The titular character's name is just "Shana", and she [[NoNameGiven didn't have even that]] before Yuuji named her [[TheyCallHimSword after her sword]]. Which is strange, as all other Flame Hazes have full names.
** Most (if not all) [[DemonicInvaders Crimson Denizens]] have only one name. Semi-justified by them being not human.
* In ''Manga/SevenSeeds'', none of the Summer A team members and candidates have family names. They were raised in a secret (and presumably illegal) government school to be the ultimate survivors (thus creating one team whose members were prepared to survive the apocalypse... shame about them coming out of the process completely traumatized), and the teachers just didn't bother assigning them surnames.
* [[FromEroicaWithLove Eroica]]'s accountant's name is James. Just James.
* In ''Manga/{{Gamaran}}'' many lesser characters have only one name, though the majority of the characters use name and surname. Interestingly, the three main [[{{Ninja}} onmitsu]] of the Muhou School have only one name, that could be a sort of codename (Tsukikage/"Moonbeams", Tsuchiryuu/"Earth Dragon" and Jinkuu/"Divine Sky").
* ''Manga/AttackOnTitan'' features Levi and Ymir, whose last names (if they ''have'' one) aren't revealed. Makes sense, as both of them have {{Mysterious Past}}s, and, in Ymir's case, [[spoiler:this is a clue that she comes from somewhere outside the Walls.]]
** Levi's surname is revealed to be [[spoiler:Ackermann]].
* Kazuma from ''Anime/SCryed'' has no family name, which is symbolic of his status as an outcast from proper Japanese society.
* In ''Manga/MinamiKe'', almost every character has only one name, regardless if it's the first name or family name. The only characters with full names are the Minami characters and Yuka Uchida.
[[/folder]]

[[folder:Comic Books]]
* Although his gangster pursuers refer to him as "[[EveryoneCallsHimBarkeep The Stooge]]", the protagonist of Paul Pope's graphic novel, ''HeavyLiquid'', is generally known as "S". "[[OneLetterName Why have a name when a letter will do?]]"
* Franchise/{{Tintin}}. BTW, in the German translation his name becomes Tim. Which is a first name in Germany too, but people still call him "Herr Tim". TwoFirstNames?
* Lyra and Skaar, from ''Comicbook/IncredibleHulk''.
* Marvel also gives us Thundra, Lyra's mother.
* When the MetalMen got human [[SecretIdentity secret identities]] towards the end of their original run, Tin and Mercury's identities were known only as "Tinker" and "Mercurio".
* Comic book versions of characters from mythological pantheons usually go by one name, as do "new" gods or godlike beings created for the comics. Such as TheNewGods, ComicBook/TheEternals, TheInhumans, etc.
* ''ComicStrip/{{Rudi}}'''s last name, if he has one at all, is never revealed. Even his doctor only calls him "Herr... er... Rudi".
* The vast majority of ''ElfQuest'' characters have only one name, justified in that they live in small tribal groups. Last names really only crop up with humans later in the timeline.
* Common in ''Comicbook/DoctorStrange''. Justifed in the cases of Dormammu, Umar, Rintrah, and Clea, who all come from other dimensions; not so much with Strange's faithful servant and long-time friend Wong.
* In the ValiantComics title ''Shadowman'', there is a humorous exchange between the titular hero's girlfriend and the sister of the villain [[TheNecromancer Master Darque]]:
-->'''girlfriend:''' So this guy Darque, no first name...
-->'''Sandria Darque:''' His first name is an unsayable symbol.
-->'''girlfriend:''' Oh...oh, like Music/{{Prince}}! Got it!
[[/folder]]

[[folder:Fan Fic]]
* While Rupert Chill of [[Fanfic/Swing123AndGarfieldodiesCalvinverse the Calvinverse]] has a full name, his partner Earl does not. This is eventually lampshaded in ''Fanfic/RetroChill'', after the antagonists are dealt with:
--> Rupert Chill was gone.\\
Retro Griffin was gone.\\
Earl... uh... Earl was gone.
* For some reason, practically every [[HumansByAnyOtherName Norman]] in ''Fanfic/WarriorsOfTheWorld'' has only one name they go by. It's implied they do have last names but those last names aren't really important to the story.
* Many, if not all, of the Changelings in the WesternAnimation/MyLittlePonyFriendshipIsMagic fanon only have one name.
* Lampshaded in [[http://archiveofourown.org/works/2045382 this]] ''Legend of Korra'' fic. Korra and Mako's application for a marriage licence hits a snag when Korra sees "full name" on the paperwork, and she [[ElephantInTheRoom suddenly realizes hardly anyone she knows has two names]]. The solution? [[spoiler: They marry each other and Asami, who isn't complaining.]]
[[/folder]]

[[folder:Film]]
* Another good (and famous) example is Palpatine, the main villain from the ''Franchise/StarWars'' films. If he has another name, it hasn't been given (canonically, at least). Same applies to Yoda, Chewbacca and prequel-villain Count Dooku.
** The prequel story "Literature/DarthPlagueis" reveals that Palpatine goes solely by the family name because, while he takes pride in his heritage to one of the oldest and most powerful families of Naboo, he's disgusted by his immediate family (especially his father) to not want any association with ''them'', specifically the name they gave him. It is also implied, though never confirmed, that Palpatine's full name is Cosinga Palpatine II. This was a ShoutOut to GeorgeLucas's very first draft of ''Franchise/StarWars'' in which the Galactic Emperor's name was Cos Dashit which in turn inspired the erroneous but very common fanon name of "Cos Palpatine".
** Other [[Franchise/StarWarsExpandedUniverse EU sources]] make it clear that "Dooku" is a family name, but give no hint as to the full name of Count Dooku.
* The majority of the sidekick cadre in ''Film/SkyHigh'' don't have last names. One of the lesser characters is also even credited to a pair of OnlyOneName actresses (Malika and Khadijah).
* The roles played by [[MarxBrothers Chico and Harpo Marx]] usually had OnlyOneName, whereas Groucho's characters usually had two names and a middle initial. An exception is ''Animal Crackers'', where Chico is "Signor Emmanuel Ravelli" and Harpo is just the [[EveryoneCallsHimBarkeep "Professor"]].
* [[Film/WithnailAndI Withnail]].
* Swan ("he has no other name"), Beef and Phoenix from ''PhantomOfTheParadise''. Winslow Leach and Arnold Philbin are generally referred to as Winslow and Philbin respectively.
* Parodied in ''Film/TheDinnerGame'': a character is actually named Just Leblanc, leading another to wonder: "Really? He doesn't have a first name?"
* ''{{Superbad}}'' - It's just [=McLovin=]!
* Lampshaded in ''{{Payback}}'', when Val Resnick's boss is trying to learn about Porter, the VillainProtagonist {{Determinator}} that is looking for revenge on Resnick. When Resnick's boss asks for Porter's first name, Val tries to think for a few seconds before being forced to admit that he doesn't know and has never heard Porter referred to as anything else. (Even Porter's LoveInterest refers to him solely as Porter).
* Nathaniel in ''{{Enchanted}}''. Even when he writes a book, the author's name is listed only as "Nathaniel".
* Although his full name, Irwin M. Fletcher, is mentioned, the titular character usually insists on being called Fletch.
* Fran in ''{{Strictly Ballroom}}''.
* Yukio from ''Film/TheWolverine''. Given she lived in the streets, she might not even know her surname.
[[/folder]]

[[folder:Literature]]
* In Franchise/TolkiensLegendarium (''Literature/TheLordOfTheRings'', etc) most cultures have only have a given name and a patronymic. Aragorn, for example, is "Aragorn, son of Arathorn". Subverted later when he names his newly-founded royal house "Telcontar", effectively making the Elvish for "Strider" his official last name.
* In the Literature/ArtemisFowl series, Foaly's first name is never given for definite but it may be Paddox. This is because his wife's name is Callabine Paddox Foaly.
* ''[[Literature/InheritanceCycle Eragon]]'' does this too with the people of Carvahall. Roran is "Roran Garrowsson".
* Aiel in ''Literature/{{The Wheel of Time}}'' have only one name (when announced formally, they specify their clan and sept too, though). They call non-Aiel by their full names all the time, and are confused when they want to be called by only half their name.
* Heathcliff from ''Literature/WutheringHeights''.
* Everyone from the anarcho-communist planet Anarres in ''Literature/TheDispossessed'' by Creator/UrsulaKLeGuin had only one name randomly assigned by a computer.
* Lampshaded in one of the ''Literature/{{Pendragon}}'' books, where Bobby says something to the effect of, 'What is it with these people? Am I the only one with two names?"
** He does it again when he goes to another territory where people only have one name. Something like, "How far along does a society have to get before they start handing out last names?"
** The people on less advanced planets (Denduron, Zadaa, Eelong) have Only One Name, and on more advanced planets (Earth, Cloral, Veelox, Quillan) they have two.
* In ''Literature/ASongOfIceAndFire'', those born as commoners in Westeros rarely have last names, leading to many characters without them. In addition, Septons (priests) and Maesters (order of scholars) discard their family name and the High Septon (head of the clergy) discards even his given one.
* Chiun from the ''Literature/{{Destroyer}}'' books, although he did change his name from Nuihc.
* The novel ''Literature/CatchTwentyTwo'' throws a twist on this: the squadron commander has a first, middle and last name. However, they're all the same, and thanks to an IBM machine with a "sense of humor almost as keen as his father's", so is his rank. His name? [[DepartmentOfRedundancyDepartment Major Major Major Major]].
* Rincewind from ''Literature/{{Discworld}}''. Once, he says that he doesn't know whether he has a first name. (His Fourecks counterpart is named Bill Rincewind, suggesting that Rincewind is his surname.)
* In the original cut of Literature/TheDarkTower Book One: The Gunslinger, Roland has no last name given (later revised editions would add it), and in fact is only referred to as The Gunslinger through most of the book. His full name doesn't originally appear until the third book.
* In [[Creator/IainBanks Iain M. Banks]]'s ''Literature/AgainstADarkBackground'', protagonist Sharrow, as a member of the highest level of aristocracy, has only a single name, while lower social classes have more names.
* Maximum Ride of er... ''Literature/MaximumRide'' is the only human-avian to have a surname in the first book. In Book Two [[spoiler: Iggy finds his family]] and consequently, a last name but [[spoiler: he abandons them because they want to sell his story]].
* In ''Literature/TheGiver'', everybody has only one name (and a serial number).
* The quaddies from Creator/LoisMcMasterBujold's ''[[Literature/VorkosiganSaga Falling Free]]'', being artificial people, didn't actually have names as such, just appellations derived from their serial numbers like "Tony" or "Claire." Some of these are unusual ("Silver") and some are downright odd ("Pramod".) In ''Diplomatic Immunity'', set 200 years later, it's revealed that so many quaddies wanted to name babies after these founding heroes that later generations were forced to allow duplicate names, with numerical suffixes to keep them all straight. There are over 99 people named "Leo" alone.
* Pasquinel from ''Centennial''.
* In the ''Literature/{{Spaceforce}}'' novels, Jez is one of the few surviving Mixitor, a vampire-like race who were massacred in an uprising by their 'bloodservants' - and she is also a member of the noble class, which was almost completely wiped out. She doesn't use either her full name Jeziandra or her 'house' name in everyday life, and it's implied that this is because she's seeking to distance herself from her DarkAndTroubledPast.
* In Creator/LewisCarroll's ''Literature/SylvieAndBruno'', the title characters. Lady Muriel in fact asks, and is told no family name.
* In ''Literature/TheColorPurple'' Albert's last name is never revealed, and Celie just calls him Mister ____.
* Garrett from ''Literature/GarrettPI'' only has the one name. It's apparently his last one.
** Presumably he does have a first name, as we know his brother had one (Mikey). Glen Cook's just avoided revealing it to tease his readers.
* In JasperFforde's Literature/ThursdayNext books, the titular character's father is referred to only as "Colonel Next". It is revealed that he actually ''has'' no first name, due to having been erased from the timeline by [[TimePolice the Chronoguard]] after he went rogue.
* Not a ''single'' character in ''Literature/TheTigersWife'' other than the protagonist has their surname revealed. Done on purpose: inter-ethnic violence is the backdrop to the story, and the author left out surnames that might be associated with an ethnicity.
* In Creator/CharlesDickens's ''Literature/GreatExpectations'', the main character Pip is raised by his sister and her husband Joe, but the sister's given name is never mentioned. She is referred to only as "Mrs. Joe".
** This is a common device of Dickens', used to dehumanise his villains, e.g. Fagin, Mr. Smallweed, etc.
** Mrs. Joe's name is mentioned once late in the book. It's Georgiana M'ria (Maria, presumably.)
* The detective Literature/{{Spenser}}, from the series by Robert B. Parker. Anytime someone asks, Spenser simply replies with "Spenser." One time, when questioned if that was his first or last name, Parker writes the line "I told her."
* The protagonist of the Polish YA series ''Pan Samochodzik'' is only ever referred to as Tomasz. His last two initials are N.N., which could be a reference to his author's last name and pen name (Nowicki-Nienacki), or the abbreviation for the Latin ''nomen nescio'' ('name unknown').
* The title character of ''Lovejoy'' is never given a first name. In the [[Series/{{Lovejoy}} TV series]] adapted from the books, it is hinted that his name may be "Malcolm", but he does not confirm or deny this.
* [[LoadsAndLoadsOfCharacters Hundreds of characters]] in ''Literature/WarAndPeace''. Zherkov, Raevsky, Tikhon, [[EvilChancellor Speransky]], [[TheStrategist Pfuel]], etc. Most of the historical characters are only referred to with one name (such as General Mack and Marshals Murat and Davout) since Tolstoy probably assumed anyone reading this book in 1870 would recognize the names from history lessons.
* StreetUrchin Fred "No-Name" in Avi's ''Literature/BeyondTheWesternSea''.
* Almost everyone in ''Literature/{{Uglies}}'', save for Tally Youngblood and Andrew Simpson Smith. Most of the ''Extras'' characters get last names, but we still never learn the last names of the characters from the original trilogy who show up. Dr. Cable is also only ever Dr. Cable, and David may not actually ''have'' a last name.
* Lucretia from ''Literature/{{Bystander}}''. And at least one of the bad guys refers to her as "Bystander," rather than using her given name.
* Elizabeth from ''Literature/HouseOfNight'', who named herself 'Elizabeth No Last Names' because she couldn't be bothered to come up with a new last name. This trope might as well be named after her!
* [[Literature/DonQuixote Al Donza]], with "Al" being a prefix like Don, only Al Donza is her real name, and Don Quixote isn't his.
* The title character of the ''{{Montmorency}}'' books never gave himself a first name when he concocted either of his two aliases, Montmorency and Scarper. For a while, people at his club thought the former identity's first name was "Xavier", but that was from someone mishearing "savior".
* Literature/InDeath series: Roarke. This is his family name; his father is named Patrick Roarke. Creator/NoraRoberts has stated that she will never, ever reveal what his given name is.
* Waco from the novels of Creator/JTEdson. He was orphaned as a baby when his family was killed in a raid by the Waco indian tribe, which is what he takes his name from.
* Laurent in ''Literature/ThereseRaquin''. We're never told if that's his first or last name.
* Quite a few in RangersApprentice, most notably Will (until book 6/7) and Halt (until book 8).
* ''Literature/CounselorsAndKings'' doesn't give the family name for Zalathorm, nor was it in any {{sourcebook}} before D&D3.5 ''Shining South'', nor is it known from the dynasty, since Halruaa is TheMagocracy and [[SorcerousOverlord Netyarch]] is not a hereditary position. As one fan [[http://forum.candlekeep.com/topic.asp?TOPIC_ID=1888&whichpage=43#112914 reasoned]],
--> Wizards don't need surnames once they've gotten good enough at what they do. And the same goes for kings, but without the bit about being good at what they do being necessary. And seeing as Zalathorm is both...
* Several characters in Creator/SergeyLukyanenko's ''Literature/LineOfDelirium'' only appear to have one name. This is justified in the case of Sedimin, the ruler of the [[SiliconBasedLife Silicoids]], as his name is synonymous with the title (the Foot of the Foundation), which he gained after becoming the ruler through KlingonPromotion. Not justified in the case of the human Emperor Grey. Nowhere in the trilogy is any other name mentioned. The [[TheCyborg Meklar]] also appear to only have one name, which tends to be written with an apostrophe or a slash (it's translated from machine code anyway). A [[BearsAreBadNews Bulrathi]] named Ahhar is, at one point, calls himself Shivukim Ahhar, although Shivukim could be a Bulrathi title or honorific. The cyborg Andrey never reveals his last name; presumably, he feels he no longer needs one, as he is not human anymore. The famous weapons designer Martyzenski doesn't appear to have a first name. Then again, he only shows up in one scene.
* Speculating about their mysterious Uncle Hoole, Tash Arranda in ''Literature/GalaxyOfFear'' proposes that he only has the one name. [[spoiler: He had two, but deliberately dropped the first after becoming TheAtoner.]]
* In the original ''Film/{{Jaws}}'' novel when Chief Brody looks for Quint the shark hunter's name in the phone book all it's listed under is "Quint".
* In the ''Literature/TheMysteriousBenedictSociety'' series, all of the Recruiters / Ten Men who work for the BigBad Mr. Curtain go by only one name. More interesting is the case of the Executives Jackson and Jillson. As described in ''The Perilous Journey'', "The children had never determined if the two Executives were brother and sister, boyfriend and girlfriend, or simply partners in crime. They didn't even know them by any names other than Jackson and Jillson -- which could have been first names, last names, or nicknames."
* Erik in ''ThePhantomOfTheOpera''. Given that he ran away from his AbusiveParents at an early age, it's possible even he doesn't know his last name--though a few adaptations grant him one.
** André in ''Discworld/{{Maskerade}}'' may well be an Expy of Erik. Despite being an important supporting character, his surname is never revealed.
* Most [[ScaryDogmaticAliens Yuuzhan Vong]] from the ''Literature/NewJediOrder'' series have both a personal name and a domain (clan or extended family) name and are referred to [[FullNameBasis using both at all times]] (so say Nom of Domain Anor is always referred to as Nom Anor, never just Nom or Anor). There are exceptions however, mostly among the priest caste (whose domain names are rarely revealed), the Shamed Ones (who have either fallen from grace and been repudiated by their domains, or were born into Shame and were never actually part of a domain, though some Shamed Ones do use domain names as an act of defiance), and the Supreme Overlord (who upon becoming Supreme Overlord transcends his caste and domain; therefore while Supreme Overlord Shimrra comes from Domain Jamaane, he would always be referred to as Shimrra rather than Shimrra Jamaane), though there are other individual cases which are not explained.
* Literature/{{Parker}}, the VillainProtagonist of a series of novels by Richard Stark. Stark decided not to give the character a first name when he thought ''The Hunter'' was going to be a standalone novel. He stuck with this decision when it became a series, even though it complicated writing the subsequent books.
* ''Literature/RazorlandTrilogy'' has Deuce, Tegan, and Stalker, though only the last stays with one name in the entire series.
* In ''Literature/TheCay'', Timothy, an illiterate black deckhand, states that Timothy is his only name.
* Elias the golem of ''Literature/GetBlank'' has no surname. Maybe if there was another golem named Elias.
[[/folder]]

[[folder:Live Action TV]]
* ''AccordingToJim'': Unlike ''Malcolm In The Middle'', the family on this show successfully avoids having any surname at all from first show to last (although Jim's sister-in-law does have one - Gibson).
* On ''Series/AgentsOfSHIELD'', "Skye" is the full name that Skye chose for herself after abandoning the one given to her by an orphanage, which she found embarrassing ([[spoiler:Mary Sue Poots]]). Her birth name is still unknown.
* ''Series/{{Angel}}'':
** The eponymous character usually goes simply by Angel. When he's evil he tends to go with the variant Angelus. Either way, it's only one name. His original human name was Liam, surname never mentioned.
-->'''Kate Lockley:''' Well, see, the thing about detectives is they have resumes and business licenses and last names. Pop stars and Popes, those are the one-name guys.
-->'''Angel:''' You got me. I'm a pope.
** In Season 3, the Angel Investigations staff at one points needs to write down a full name for him on a government document, so they improvise "Geraldo Angel."
** Spoofed when Angel starts making out with Eve, despite Angel's protests that he doesn't even know her full name.
-->'''Angel:''' I mean, do you even have a last name?\\
'''Eve:''' Do you?
* ''Series/BabylonFive'':
** Some aliens, notably Minbari and Narns, go by only one name, whereas others, notably Centauri, go by two.
** Although the Narns have only one name, it actually consists of two halves divided by an apostrophe. For instance, main character Na'Toth is the daughter of Shak'Toth.
*** And it is stated in one episode that Narns have a single name at birth, and the apostrophed appendage (actually prefix) is added when they have chosen which religious figure they will be devoted to spiritually: "G'" denotes a devotee to G'Quan (which G'Kar was), for instance.
** The three techno-mages that are officially named in the series and its spin-off series ''Series/{{Crusade}}'' are Elric, Galen, and Alwyn respectively. Although all three have Human origins, none of them have a last name.
* ''Series/BattlestarGalacticaClassic'': No one in the original show had a last name. (This has changed in the [[Series/BattlestarGalacticaReimagined reimagined version]]; many of the original pilots' names are now the callsigns of their revised counterparts, and "Adama" has become a family name.)
* ''TheBigBangTheory'': Penny seems doomed to go through life without a surname.
* ''{{Blackadder}}'': Baldrick is only known by this name, regardless of which incarnation he is. However, Baldrick speculates in the third series that his first name may be 'Sodoff' and in the fourth season was known as Private S. Baldrick.
* ''Series/BlakesSeven'': Cally is never known by anything else -- as far as we know, no Aurons have more than one name.
* ''Series/BuffyTheVampireSlayer'':
** Kendra tells Giles that she "has no last name" in the second episode she appears in. However, this has become a SubvertedTrope as [[WordOfGod Joss Whedon]] has subsequently revealed, outside of the series, that her surname is actually Young - which she didn't know as she was raised by her Watcher.
** Other BuffyVerse characters with no last names include Faith, Spike, and Angel. Spike was revealed to be a self-given alias, his first name being William, and Faith was revealed to have the last name of Lehane [[WordOfGod by Joss Whedon]] when the makers of the official spin-off RPG asked. Angel turned out to have a different first name (Liam, which is an Irish version of "William"), but no last was ever given. Spike's human surname, according to ExpandedUniverse, is Pratt.
** Buffyverse Vampires, some of whom take or are given new names are fond of this trope, including aforemention Angel and Spike, as well as Drusilla, Penn, Luke, and Dracula.
** None of the Potential Slayers are given a last name, not even Kennedy.
* ''Series/BurnNotice'': Most of the people Michael Westen crosses swords with. Most of the [[MonsterOfTheWeek job of the week villains]] will not be given more than one name, while many others will be given full names in passing which are never referenced again. All of the MythArc villains tend to go by singular names that are most likely pseudonyms (for example, Carla, Victor, and Simon).
* Series/{{Columbo}}:
** Lt. Columbo (No first name).
** Same for Mrs. Columbo.
*** Not exactly true: Kate Mulgrew's series ''Mrs. Columbo'' became ''[[TheDanza Kate Columbo]]'', then ''Kate the Detective'' and then ''Kate Loves a Mystery'' before it became [[{{Cancellation}} Kate Doesn't Detect Here Anymore]].
**** And then Lt. Columbo said that ''that'' woman was an impostor...so we re-iterate, same for Mrs. Columbo.
** His ID card identified him as Frank Columbo, but that was only onscreen for a few seconds and reportedly isn't canon.
*** A trivia encyclopedia gave his first name as Philip, but this turned out to be a copyright trap - as the creators of ''Trivial Pursuit'' discovered when the book's author sued them for plagiarism. (He won, but the decision was reversed on appeal.)
* ''DarkAngel'': The main character was named Max, with no last name (she did use the last name Guevara on occasion, but she made this up). Her fellow X5s (Zack, Alec, Ben, etc) also had only one name, as did the dogboy Joshua. Alec's fake surname was supposedly [=McDowell=], but it was never spoken aloud.
* ''DeadLikeMe'': Mason has no known ''other'' name, and the name that he does have could really be either his first or last name. Kiffany doesn't have a last name, but since she has a lot less screen time than Mason, it's slightly less odd.
* ''Series/DoctorWho'':
** Adric, Nyssa and Romanadvoratrelundar (Romana for short) in the old series. Although the Doctor did once refer to the latter as 'Miss Dvoratrelundar', her name is always written as one word.
** In the new series, the Doctor's daughter Jenny has no surname. [[IAmNotShazam Unless it's "Who".]]
** The televised series never revealed the surnames of the Doctor's companions Vicki, Polly and Ace. [[WordOfGod Production documents]] give Polly's surname as "Wright"; in the Franchise/DoctorWhoExpandedUniverse Vicki's surname is Pallister, and Ace's is either Gale or [=McShane=] (or possibly both). (Gale appeared in production documents, with the notes that they might want to change it, depending on the plot requirements of the story in which the reveal occurred, if it happened at all.) (The name "Dorothy Gale" [[ShoutOut references]] ''Literature/TheWonderfulWizardOfOz''.)
** The ''Magazine/DoctorWhoMagazine'' comic gives us Destriianatos (Destrii for short).
** The AudioPlay/BigFinishDoctorWho audios give us C'rizz and Erimemushinteperem (Erimem for short).
* ''{{Entourage}}'': Ari Gold's wife has no first name. She is simply referred to as Mrs. Ari (not even Mrs. Gold), despite more and more screentime each season. WordOfGod says she'll never get a first name, but fan speculation says its something like Deena or Dina, based on a muffled introduction at a bat mitzvah in the first season.
* EverybodyHatesChris: Chris and his family (Julius, Rochelle, etc.) never have their surname mentioned. Although it is often assumed to be "Rock" as the series is semi-autobiographical based on Chris Rock's high-school years, the show nevertheless goes to great lengths to never mention it.
* ''{{Friends}}'':
** In one episode, Rachel can't remember the name of her last boyfriend, Joshua, after pretending it had been a "deep and meaningful relationship". She therefore says that he had only one name, like Moses.
** The name of the boyfriend whose last name she couldn't remember was actually ''Tag''. He must be feeling pretty good about himself right about now....
* ''GilligansIsland'': The title character during its run. After the show was cancelled, WordOfGod revealed that his first name was Willy.
* ''{{Glee}}'': Brittany in the first season. Her last name doesn't even show up on the school yearbook. However, in the episode "Britney/Brittany" from the second season she reveals that her name is Brittany [[spoiler: S. Pierce]].
* ''GreenWing'': Never reveals the first names of Dr. [=MacCartney=] or Boyce.
* ''HomeImprovement'': Wilson W. Wilson Jr. He's called by OnlyOneName, because that ''is'' his only name - [[RepetitiveName first, middle and last]].
* ''Series/HowIMetYourMother'': Has Carl, the owner of [[LocalHangout MacLaren's]], who is upset upon finding out that Marshall didn't know his last name (neither does the audience).
** [[FridgeLogic Is it not Maclaren?]]
** Ted's girlfriend (and almost fiancee) Victoria was never given a last name.
* ''HumanTarget'':
** Winston and Guerrero are usually only ever called by their last names. Eventually we find out why Winston keeps his first name under wraps: it's Laverne. We never get one for Guerrero, but it's highly unlikely that Guerrero is his real last name.
** Guerrero's name alone is enough to get most people to crap their pants. This happens to a thief he captures in one episode. Before he can even start the "interrogation", his name is mentioned, and you can see her visibly deflate and lose all bravado.
* ''InspectorMorse'':
** In the television version. The source novels provided only an initial, E. Name eventually revealed as 'Endeavour'.
** In his university days, he was nicknamed "Pagan", because he wouldn't give his Christian name.
* ''ItsAlwaysSunnyInPhiladelphia'': All the main characters have full names except for Mac. For seven seasons, it was not known whether Mac is a first name, last name, or a nick name, and his mother is often addressed as "Mrs. Mac" to keep the gag running. The season seven finale eventually revealed his name to be [[spoiler:Ronald [=McDonald=]]].
* ''KidsIncorporated'': Almost no one on this show has a last name, sometimes awkwardly so, such as in "The Hero" where Devyn is introduced on an interview show by her first name, with an audible pause because the interviewer's rhythm was thrown off by the lack of a last name. On several occasions, particularly in dream sequences, a character will give an obviously fake last name (Ryan Lambert once uses "Ryan Ryan", and once "Ryan von Ryan"). Since most characters were TheDanza, it may be implicit that they have the same surnames as their actors, though this wouldn't work for, say, Renee Sands and Stacy Ferguson, whose characters were siblings.
* ''Series/{{Leverage}}'':
** Parker is the only character who isn't given a first name, even in her official character bio. This does make sense in the canon, however - she ran away from home (or something) and spent most of her childhood in and out of foster homes. It's implied that she eventually just ran away and became a thief, and that she doesn't need a full name because she lives off the grid.
** May be a shout-out to the title character in Richard Stark's ''{{Parker}}'' crime novels, who also is a thief and also has just the one name.
* ''MalcolmInTheMiddle'': The family's last name is never given -- almost. In the pilot episode, the name tag on Francis' military school uniform read "Wilkerson." The decision not to reveal the family's last name was made during production of the pilot, but apparently they missed Francis' name tag. However, the series finale provides a different last name for the family. During Malcolm's graduation ceremony, Francis drops an employee ID card, the last name on which reads "Nolastname". It was also a joke amongst those who worked on the show that the family's last name WAS "Nolastname".
* ''{{Series/Merlin}}'': The only people with last names are the Pendragons, being royalty.
* ''MissionImpossible'': Paris. Amusingly, Paris was played by Leonard Nimoy, famous for playing Spock of ''Star Trek''. Paris had occasion to say, "He's dead, Jim."
* ''Series/MrBean'': The title character is never given a first name, perhaps because it is heavily implied by the opening credits that he is an alien. The spin - off book ''Mr Bean's Diary'' contains an old school report of his, but his first name is obscured by an ink blot on the page.
* ''TheNanny'': Niles, the butler from , even puts a LampshadeHanging on this at one point:
-->'''Fran''': Say, what ''is'' your last name?
-->'''Niles''': It's just Niles. Like Cher.
* ''Series/TheNewAvengers'': Purdey.
* ''NewsRadio'': Beth claims not to have a last name.
* ''Series/OnlyFoolsAndHorses'': Sid.
* ''Franchise/PowerRangers'':
** Most alien-but-still-human-ish Power Rangers, such as Andros and Karone, or Maya. ''Time Force'''s resident alien, Trip, has a very popular {{Fanon}} last name purported to come from scripts or casting sheets, but unlike other such surnames (e.g., Billy Cranston, Katie Walker), it wasn't included on Disney's official website.
** Speaking of Billy Cranston and Katie Walker, it is ''very'' common for Rangers to be known only by first names, and some Rangers' last names are only known by WordOfGod in the form of network websites (that are often ''wrong'' about things like last names, ages, and dates when we finally do get them - even Cranston and Walker come from the same source as Sky Blake and Jack and Z Manners [[note]]''Series/PowerRangersSPD'' takes place in 2025 and it's Sky Tate, Jack Landors, and Elizabeth "Z" Delgado. Jack and Z aren't even the same ethnicity. Network and toy-company sites often work with first-draft information.[[/note]]) Of the original Series/MightyMorphinPowerRangers, we didn't get "Zack Taylor" and "Trini Kwan" until the ''day of their departure,'' and had heard "Jason Lee Scott" ''once'' before. Tommy Oliver and Kimberly Hart, the first last names we get, are heard a mere ''54'' episodes into the original series! And again, though his tenure lasted 202 episodes, we never heard Billy's. Last names weren't deliberately avoided, just... if nobody had a good reason to speak it (martial arts tournament, TV appearance, etc.) it didn't get spoken.
* ''ThePretender'':
** Jarod, the lead character, adopts a different surname each episode. Initially, this is because he doesn't know his real surname, but even after he locates and spends time with his father, his real surname is never revealed. (This sometimes causes dialogue clunkiness, not so much with Jarod as with his father, who is referred to as "Major Charles" always, by everyone, in all contexts.)
** Then there's Miss Parker, who is never given a name. Fan speculation has given us the possibility of "Angel", her father's nickname for her, being her actual name.
** Sydney and Lyle, who only go by their first names, and Broots, who only goes by his last name.
** In fact, almost all of the major characters in ''ThePretender'' go by one name only, the one exception being Mr. Raines, who eventually turned out to be a William. Several of these characters go to remarkable lengths to keep their names secret -- CorruptCorporateExecutive Mr. Parker, for instance, somehow managed to persuade the celebrant of his on-screen wedding to leave his full name out of the vows (as did [[{{Quincy}} Quincy]] and the Kid (from ''TheYoungRiders'') in their wedding episodes) -- leading some to suspect that the writers themselves don't actually know what their names are.
* ''PushingDaisies'': Ned doesn't seem to have a last name. Neither of the people related to him seem to, either, in contrast with the narrator's habit of referring to everyone by their full names. It's not even clear what 'Ned' is an abbreviation of. Most likely it's Edward, but it could also be Edmond, Edgar or even [[ASongOfIceAndFire Eddard]]. Or it could just be ''"Ned"''....
* ''{{Quincy}}'': Like Columbo, this title character never had his first name revealed (not even by his wife!).
* ''Series/{{Revolution}}'': The following non-exhaustive list of characters in season 1 have only one name: Jimmy, Billings ("[[Recap/RevolutionS1E18Clue Clue]]"), Cutrone ("[[Recap/RevolutionS1E16TheLoveBoat The Love Boat]]"), Fletcher ("[[Recap/RevolutionS1E2ChainedHeat Chained Heat]]"), Graves ("[[Recap/RevolutionS1E17TheLongestDay The Longest Day]]"), [=McCoy=], Reed ("[[Recap/RevolutionS1E14TheNightTheLightsWentOutInGeorgia The Night the Lights Went Out in Georgia]]"), Ryan, Simpson ("[[Recap/RevolutionS1E12Ghosts Ghosts]]"), Templeton ("[[Recap/RevolutionS1E1Pilot Pilot]]"), Nicholas, Albert ("[[Recap/RevolutionS1E3NoQuarter No Quarter]]"), Ashley ("[[Recap/RevolutionS1E9Kashmir Kashmir]]"), Rose ("[[Recap/RevolutionS1E8TiesThatBind Ties That Bind]]"), Rosie ("[[Recap/RevolutionS1E13TheSongRemainsTheSame The Song Remains the Same]]"), Sam, Trevor (two characters with that name), [=McCready=] ("[[Recap/RevolutionS1E17TheLongestDay The Longest Day]]"), Drexel ("[[Recap/RevolutionS1E6SexAndDrugs Sex and Drugs]]"), Audrey ("[[Recap/RevolutionS1E7TheChildrensCrusade The Children's Crusade]]"), Beth, Boggs, Brian, Caleb, Carl, Davis, Duane ("[[Recap/RevolutionS1E15Home Home]]"), George, Jack, Jacob, Lily, Michael, Peter, Rob ("[[Recap/RevolutionS1E5SoulTrain Soul Train]]"), Rudy ("[[Recap/RevolutionS1E4ThePlagueDogs The Plague Dogs]]"), Sean, Skip, Sonia, Spencer, Steve (two characters with that name), and Vidal. Most of them are minor one-shot characters, but a couple of them are recurring characters.
* ''TheSarahConnorChronicles'': Cromartie is one of these. They even lampshade it ''in his very first scene''.
-->'''Cromartie''': Mister Ferguson is ill today. My name is Cromartie.
-->'''Student''': Is that your only name, like Madonna?
-->'''Cromartie''': Madonna? Why? No.
* ''{{Seinfeld}}'': Newman's first name is never mentioned at all, even on his [[http://www.stanthecaddy.com/images/the-package1.jpg business card]]. And for a long time Kramer was this, until the episode revealing his first name is Cosmo.
* ''{{Sharpe}}'': Harris is never given a first name. This is given a LampshadeHanging in ''Sharpe's Waterloo'' - Hagman, who has served with him for years and presumably knows him very well, asks "So what ''is'' your first name?"
* ''Series/StargateSG1'':
** Teal'c. For that matter, most of SG-1's aliens do not have family names.
** However, this is averted in ''Series/StargateAtlantis,'' where most aliens, including regulars Teyla Emmagan and Ronon Dex, do have first and last names. This raises an interesting question: how is it that Earth alone uses a naming system unheard of in the Milky Way galaxy but commonplace in the Pegasus Galaxy?
*** Well, the majority of the humans in the Milky Way were ruled, and thus had their cultures influenced by, the Goa'uld, whereas the Pegasus Galaxy and post-Goa'uld Earth were more influenced by the Ancients. That could be one way of hand waving the entire problem.
*** Except most Ancients in the show don't have last names, either.
*** A lot do. The first one SG-1 meets is Oma Desala. The first one the Atlantis team meets is Chaya Sar. The one SG-1 meets ''in'' Atlantis is Ganos Lal, aka Morgan le Fay.
** The Jaffa sometimes tack place of origin (or current affiliation, in the case of "Teal'c of the Tau'ri") onto another Jaffa's name (and sometimes that of a human) as if this constituted a type of full name in their culture.
* ''Franchise/StarTrek'':
** Klingons may also have a {{patronymic}} ("Worf, son of Mogh") and a House name ("Worf of the House of Mogh", later the House of Martok), but do not have true last names. Vulcans might be the same, depending on which set of contradictory evidence you prefer.
** Then there's Chakotay.
** We also have Data. And Odo. And Laas.
*** Wan't Odo's full name Odo Ital? I might be misremembering...
*** By rights, Data could've been Data Soong, but chose not to do it.
** And Neelix. And Kes.
** Trill symbionts have only one name, and hosts use it as a surname when joined, dropping the family name. Thus, Ezri Tigan became Ezri Dax when joined with the Dax symbiont.
** ''Deep Space Nine's'' Dukat never got a first name in the series. {{Fanon}} based on novels gave it as "Skrain." Other Cardassian characters got full names, like Elim Garak, Enabran Tain and Tora Ziyal (though Ziyal's is Bajoran-style, rather than being "Ziyal Dukat", for [[ChildOfRape a good reason]]).
** One episode of ''Series/StarTrekTheOriginalSeries'' claims Spock's last name cannot be pronounced by humans, but others seem to indicate he has [[OnlyOneName no last name at all]]. Diane Duane's ''Spock's World'' speculates that Vulcans use patronymics, so Spock's full name, according to her, is "Spock cha'Sarek".
*** Actually, the name that couldn't be pronounced was merely called "another name" in one episode and "the Vulcan name" (implicitly the family name) in another. Since not all cultures put the family name last or even have family names in the Western sense, we don't know if Spock's unpronounceable name is his first or last name. Continuity editor D.C. Fontana decided that this other name was "XTMPRSQZNTWLFB". Linguist fanfic author Dorothy Jones actually worked out a pronunciation and etymology for that sucker.
** Similarly, Sulu's first name was not given in ''Franchise/StarTrek'' canon until the 6th movie in the series. The name Hikaru actually came from one of the first published novels, ''The Entropy Effect''.
** Uhura's first name was unrevealed for a while, although the novels consistently use "Nyota" (Swahili for "star"), coined by pro SF author William Rotsler. The new movie confirmed this.
** On ''Series/StarTrekTheNextGeneration'', O'Brien didn't get a last name until his third appearance, and didn't get a first (and middle) name, Miles Edward, until three years after his first appearance. He's an AscendedExtra, so it's excusable.
** The Vorta, none of whom have family names. Understandable, as they don't have families, but they do each get a number tacked on to their name, so that's something.
** None of the named Romulans (e.g. Sela, Donatra, Tel'Aura, Tomalak) appears to have a last name. Given that they're an offshoot of Vulcans, this may be a JustifiedTrope. However, at least one non-canon novel has a character refer to a Romulan by name. Specifically, Captain John Harriman (the inept captain of the ''Enterprise''-B, whom the book turned into a {{Badass}}) purposefully calls Admiral Vokar by his first name Aventeer, knowing the latter would perceive it as an insult.
*** There is one exception to this, Admiral Alidar Jarok. Though you'd be forgiven if after watching the episode he appeared in you made the mistake of thinking "Alidar" was an alias rather than his first name.
* ''{{Supernatural}}'':
** The angels all only have a first name.
** Reapers as well.
** Lilith and Cain are the only demons to go by their human names, and neither of them apparently have surnames. The rest of the demons don't remember their previous names (except for Crowley, and he doesn't use it), and apparently just pick a random human name when they're on Earth. There's at least one instance of a demon using the name of its vessel (Meg Masters), even after switching to a new vessel.
* ''Series/TrailerParkBoys'': None of the characters outside of the Lahey family have surnames (and Bubbles is never even given a proper first name, "Bubbles" is explicitly stated to be a nickname). This gets comical when the main characters go arrested or go to court and the cops and judges only call them Julian or Ricky.
* ''Series/{{V}}'': The Visitors in both the original and [[Series/{{V 2009}} new series]] go only by a first name.
* ''Series/VengeanceUnlimited'': Mr. Chapel's first name is never revealed. Though the likelihood of Chapel itself being a pseudonym is rather high in this regard.
* ''{{Vintergatan}}'': The protagonists usually only had one name...then it becomes an AvertedTrope with the second season, when they got last names too.
* ''Series/WhatNotToWear'': Carmindy, the makeup expert.
* ''WhatILikeAboutYou'': Vince and Lauren are the only main characters to not have their last names ever mentioned in any of the show's 4 seasons. Recurring characters Peter and Rick don't appear to have last names either.
* ''Series/YoungBlades'': Siroc. It's unclear whether this is a first or last name.
[[/folder]]

[[folder:Music]]
* Music/{{Madonna}} and Music/{{Prince}}, though in both cases it's actually their real first name.
** To add insult to injury, Prince used an [[LuckyCharmsTitle unpronounceable symbol]] for his name for most of the 1990's, for legal reasons.
* Similarly, Music/{{Rihanna}} is always known as just "Rihanna", but that's actually her real ''middle'' name (her full name is Robyn Rihanna Fenty).
* There's also Cher, which is actually short for Cherilyn". (Her full name is Cherilyn Sarkisian.)
* And Music/{{Beck}} (Beck David Hansen). And Jewel (Jewel Kircher).
* And from the 60s, Donovan, [[http://www.youtube.com/watch?v=D0Engn3Ar3k Melanie]], [[http://www.youtube.com/watch?v=gAnpvh6nC4U Melissa]] and [[Creator/RichardBrautigan Victoria]].
* And, to top it off, Music/{{Morrissey}}, who uses only his ''surname'' (in full, it's Steven Patrick Morrissey).
* Similarly, Liberace only used his surname. Understandable, as his first name was Wladziu.
* VisualKei, full stop. Nearly ''every'' musician in the movement uses a single name (often their given name or a shortened version of it), and it's not unheard of for two (or more) different musicians to have the same stage name. This is why, when people talk about specific performers, they almost always specify which band(s) they are/were associated with; how else is someone going to know [[http://visualkei.wikia.com/wiki/Yuki which Yuki you're talking about]]?
* Nena (Gabriele Susanne Kerner), of [[http://www.youtube.com/watch?v=jQYQTFudrqc 99 Luftballons]] [[OneHitWonder fame]].
* Music/{{Beyonce}} (full name: Beyoncé Knowles) after Music/DestinysChild.
* Music/{{Shakira}} - except at UCLA.
* [[Music/CherylCole Cheryl]] after her divorce for solo work.
* 90's R&B princesses Shanice, Brandy, Monica, and Aaliyah.
* Arianna of The Frozen Autumn.
* Music/TriciaBrock dropped her surname for her sophomore solo album.
* Dion (his first name[[note]]As opposed to "Music/CelineDion"[[/note]]), a singer from the 1960s, known for hits such as "Teenager in Love" (with his band Dion and the Belmonts), "Runaround Sue", "The Wanderer", and "[[AbrahamLincoln Abraham]], [[MartinLutherKingJr Martin]], and [[JohnFKennedy John]]".
* Harry Nilsson, another singer from the 1960s, was sometimes credited as simply "Nilsson".
* Björk [[{{Patronymic}} Gudmundsdottir]], better known as simply [[Music/{{Bjork}} "Björk"]], even in her native Iceland, and even when she's not performing, because "Gudmundsdottir" isn't a surname, but {{Patronymic}}; Icelanders ''don't have'' last names.
* Marta Marrero, better known as "Martika".[[note]]When she was first cast in Series/KidsIncorporated (where she was one of the few non-[[TheDanza Danzas]]), she was originally billed under her real name.[[/note]]
* Kristine, a Greek retro {{New Wave| Music}} artist.
* Mexican singer Yuri (full name: Yuridia Valenzuela Canseco)
* {{Music/Selena}} (no, not [[SelenaGomez her]]...)
* [[Music/BoAKorea BoA]]

[[folder:Mythology]]
* Merlin, Sir Kay, Guenivere, Percival... in the [[KingArthur Arthurian myths.]]
* In ClassicalMythology, NorseMythology, and EgyptianMythology, and nearly every other set of ancient stories, characters have only one name just as it was with most ancient cultures.
[[/folder]]

[[folder:Newspaper Comics]]
* {{Popeye}}
* While the human characters in ''ComicStrip/CalvinAndHobbes'' presumably have two names, even though we're not told them except for "Susie Derkins" (and no names at all in the case of Calvin's parents, who, again, are not presumably nameless in-universe), Hobbes is a tiger, so it's quite possible he's really just "Hobbes".
[[/folder]]

[[folder:Professional Wrestling]]
* Wrestling/{{WWE}} has a strange habit of giving a large number of their Divas only one name. While wrestlers going by only one name have always been pretty common (even now, there's Wrestling/{{Fandango}} and Wrestling/{{Ryback}},) they, at least, are distinct titles, whereas the Only One Name Divas are usually rather generic first names, such as Wrestling/{{Maryse}}, Wrestling/{{Layla}}, Maria, Wrestling/{{Melina}}, Maxine, [[Wrestling/NatalyaNeidhart Natalya]], Wrestling/{{Emma}}, and Wrestling/{{Paige}}. Also noticeable is that the WWE fanbase has actively revolted against this, often using a CanonName, such as names they used in developmental, to the extent that WWE has acutally started using them again, as has happened with Cameron Lynn, Naomi Knight, and Wrestling/AJLee. There's a variant where a Diva will only have a first name, but one that's in two parts, such as Summer Rae and Eva Marie.

[[folder:Television Commercials]]
* A recent (May 2012) Progressive Insurance commercial has a close-up shot of Flo's driver's license that reveals that she has no middle or last names.
[[/folder]]

[[folder:Theatre]]
* Belize from ''AngelsInAmerica''; Most of the other main characters get specified middle names, for crying out loud, but not Belize.
** It's explained [[ExpandedUniverse in the character page of the printed version of the script]] that his given name was Norman Arriaga; "Belize is a drag name that stuck".
* The title character of ''{{Elling}}''. Made all the more curious by the fact that no one mentions it even though everyone refers to his roommate using a FullNameBasis.
* Creator/WilliamShakespeare's plays sometimes did this to fit the setting (ancient Greece, ancient Egypt, etc)...''except'' when dealing with comedic characters. This was because, [[AnachronismStew no matter what the setting or time period, the comedy characters would always be based on Elizabethan-era peasants]]--and in the Elizabethan era, people had last names. That's why, for instance, the main characters in ''AMidsummerNightsDream'' are named simply "Demetrius", "Theseus" or "Hermia"--but the peasant caricatures putting on the [[ShowWithinAShow play-within-a-play]] are named "Nick Bottom", "Tom Snout", "Peter Quince", and so on.
[[/folder]]

[[folder:Video Games]]
* ''[[VideoGame/TwentyTwentySeven 2027]]'': Daniel's last name is never revealed.
* In ''Franchise/{{Halo}}'', the Master Chief is only known as John-117. The closest thing we have to a family name for him is this MIT prank claiming that he's actually [[http://hacks.mit.edu/Hacks/by_year/2007/halo3_john_harvard/ John Harvard]].
** This sort of thing applies to every SPARTAN-II SuperSoldier; because all of them were "recruited" and brainwashed by the military as children, none of them remember their family names, which were replaced by designation numbers. The only SPARTAN-II who even uses a surname is Kurt-051, who was given the last name of Ambrose as a cover when he was assigned to trained the [=SPARTAN-IIIs=]. However, expanded universe material have gradually revealed the original surnames of more and more [=SPARTAN-IIs=]: so far, we know of [[spoiler:Kurt M. Trevelyan, Naomi Sentzke, Carris R. Pernault, Frederic Ellsworth, Linda Pravdin, Douglas Rutland, Jerome Cable, and Alice Treske]].
** Lower-ranking Covenant races, like [[SlaveMooks Grunts]] and [[SpacePirate Jackals]], are not allowed to have surnames, due to the [[ProudWarriorRaceGuy Elites]]' belief that names are a privileged for only the worthy. On the other hand, the [[KillerSpaceMonkey Brutes]] don't seem to care for surnames to begin with.
** In Literature/TheForerunnerSaga, the long-dead Yprin Yprikushma is the only character in the entire trilogy to have a surname; neither the highly-advanced Forerunners nor [[spoiler:the prehistoric remnants of the once-advanced human and San 'Shyuum civilizations]] seem to use them, period.
* Both ''KnightsOfTheOldRepublic'' games have many examples. Every Jedi Master ever given a name, Kreia, the Handmaiden's name ([[spoiler:Brianna]]), the Disciple's name ([[spoiler:Mical]]), Mira, Juhani, Malak, Revan, all of the Wookies, and more.
* ''Franchise/MassEffect'' averts this with everyone except for Legion and ([[spoiler:until he joins Clan Urdnot]]) Grunt. Then again, except for Ashley, Kaidan, and a few formal situations involving Tali, almost nobody's last name is ever mentioned.
** In ''Franchise/MassEffect'', and ''VideoGame/DragonAgeII'', due to limitations on the system the player character is only ever referred to by his/her last name (Shepard and Hawke, respectively).
** In the ''Franchise/DragonAge'' universe, no non-[=PC=] Dalish has a last name, and [[BlackMagicianGirl Morrigan]] doesn't have a family name. The game doesn't give family names for [[JeanneDArchetype Leliana]] or [[BoisterousBruiser Oghren]] either. [[ProudWarriorRaceGuy Sten's]] true ''first'' name is never even revealed, and while Alistair arguably has a surname, [[spoiler: it isn't used because it would be a spoiler, and because he's not interested in announcing his RoyalBlood to everyone he meets.]]
*** Very few non-player characters actually have last names given in-game, either, and most of them are nobility. [[FridgeBrilliance This may be a]] ShoutOut to ASongOfIceAndFire, which was acknowledged as an influence on the series.
*** The Qunari in general don't have last names. Even their first names are merely titles and can be taken away. Anyone who joins the Qun also sheds their name.
*** Fenris's former master is a powerful (in both magic and political power) Tevinter mage named Danarius. No last name either, despite his high status in the Imperium.
* ''Franchise/{{Pokemon}}'' characters other than professors rarely have last names (exceptions include [[VideoGame/PokemonRedAndBlue Daisy Oak, Blue Oak]] (having last names due to being a professor's grandchildren), [[VideoGame/PokemonRubyAndSapphire Steven Stone]] from the main series of games, Blake Hall and the rest of the Hall family from ''VideoGame/PokemonRanger: Shadows of Almia'', and Ash Ketchum and Gary Oak from the anime (who likely only have last names in the English version [[LipLock to give enough syllables]]).
* Most characters in ''VideoGame/DevilMayCry''. Kalina Ann appears to be the sole exception, but it's not even clear if "Ann" is her maiden name or a middle name, or even if "Kalina" is really the [[ICallItVera rocket launcher's own name/model]]. The name of Dante's father, Sparda, has occasionally been used in the context of a family name, but whether it really is is unknown.
** That said, Dante joins the ranks of given name + patronymic, with demons frequently referring to him as "Dante, Son of Sparda". Same may be said about Vergil, too.
* Many, ''many'' Nintendo characters. As a rule of thumb, only futuristic characters are given full names ([[{{Metroid}} Samus Aran]], [[VideoGame/StarFox Fox McCloud]], [[VideoGame/{{F-Zero}} Captain Douglas Jay Falcon]]), while [[OneMarioLimit the iconic Mario]] has OnlyOneName (except in ''The SuperMarioBrosSuperShow'' and [[VideoGameMoviesSuck the movie]], where it's [[RepetitiveName Mario Mario]] to justify the term ''Mario Bros''), and so do most other characters of his series. Other series:
** ''Zelda'': Link, Zelda, Ganondorf, just to name the central three.
*** However, Ganondorf was given the last name "Dragmire" in the English manual for ''VideoGame/TheLegendOfZeldaALinkToThePast''.
*** Zelda's last name is Hyrule, given that King mentioned in ''VideoGame/TheLegendOfZeldaTheWindWaker'' is named Daphnes Nohansen Hyrule.
** ''VideoGame/DonkeyKong'' is the exception. He and Diddy are the only ones that are displayed with the full name in ''VideoGame/SuperSmashBros'', too.
** Older heroes like Pit (Kid Icarus), the Popo and Nana (Ice Climbers).
** Many of the other hunters mentioned in the ''{{Metroid}} Prime'' series only have one name.
** Nearly every character in the ''FireEmblem'' franchise, with a few exceptions : Alpine Alm Rudolf from ''Gaiden'', Celice Baldos Chalphy and Leaf Faris Claus from ''Seisen no Keifu'', the Reed family (Brendan, Lloyd and Linus) of ''Rekka no Ken'', and Princess Elincia Ridell Crimea, Jill Fizzart, and her father Shiharam Fizzart of ''Path of Radiance''.
** Mario's enemy King Bowser Koopa and his family, on the other hand, do have a surname ([[CaptainObvious Koopa]]) and first names. In Japan he's just "Daimaou Koopa," more of a title than a name.
*** And each of the Koopalings has only one name [[http://www.youtube.com/watch?v=aA_wvWK9KxU#t=5m03s in the Japanese version]] (compare with the [[http://www.vgmuseum.com/end/snes/a/smasworld-13.gif English version]]).
** Everyone in ''AnimalCrossing'' who isn't a tanuki. [[http://www.aibohack.com/nds/ac_source.htm ROMSAVE.txt]] reveals that the DS game stores a number from 0-65535 along with each human character's name that presumably represents an index into a list of surnames, but these aren't displayed in-game.
** Many of the main party members from the ''VideoGame/EarthBound''/''Mother'' series have OnlyOneName.
** Krystal, from the ''VideoGame/StarFox'' series, lacks a surname for plot reasons.
** Every character in the entire ''VideoGame/{{Kirby}}'' franchise has just one name, most notably Kirby, Meta Knight, and King Dedede.
* A few "mysterious" characters follow this trope in ''VisualNovel/PhoenixWrightAceAttorney'': Godot (though his full name is revealed later), Iris, and Bikini, for example, are referred to by Only One Name even in court. [[spoiler:We can assume that Iris gave up her family name (Fey) when she joined the temple]].
* Every single character from ''VideoGame/GoldenSun'' has only one stated name. A comment by Kraden implies they do have multiple names[[note]]"Isaac, since when were you on a first-name basis with the Wise One?"[[/note]], but none of them are ever revealed to the player.
* Seth and Kane in ''VideoGame/CommandAndConquer'': In the first briefing of the Nod campaign, Seth introduces himself as "Seth... just, 'Seth'." Likewise, the news report at the end of the GDI campaign refers to Kane as Nod's "single-named" leader.
** You also have Boris. Averted, for the most part, in ''Red Alert 3'', where every named Russian character may be only known by one name but has a full name (minus patronymic) listed in the manual. Played straight with Emperor Yoshiro and Crown Prince Tatsu, but that's typical for Japanese emperors to only have one name (e.g. Hirohito, Akihito).
* ''VideoGame/{{STALKER}} - Shadow of Chernobyl'' goes further than many with this trope. ''Every'' unique character has only one name - only generic characters have two names.
** Granted, most unique charecters are OnlyKnownByTheirNickname but the trope is still played straight elsewhere.
* Square(enix) just can't decide whatever characters need surnames, or not:
** ''VideoGame/FinalFantasyIV'' has several characters that fit this trope: Rydia, Tellah, Palom, Porom, and [=FuSoYa=].
*** [=FuSoYa=] is almost certainly a compound name that is essentially two or three names with no spaces between then, both due to the camelcase and the fact that he has a brother named [=KluYa=].
*** This can also be because Rydia, Tellah, Palom, and Porom are commoners, and thus do not have last names in this medieval world unlike Cecil, Rosa, Kain, Edward, Yang, and Edge (whose full name is Edward Geraldine) who are of the higher class.
** ''VideoGame/FinalFantasyVII'', on the other hand, gave almost EVERY character a surname (Cloud Strife, Aerith Gainsborough, etc...) though Sephiroth and his father Professor Hojo remain notable exceptions.
*** One character in the Compilation actually got an upgrade from this to a MeaningfulName, going from just Lazard in the Japanese version to Lazard Deusericus in the English Version. Meaningful because [[spoiler:Deusericus is the Latin rendering of Shinra (both meaning "Silken God"), hinting that Lazard is in fact the bastard son of President Shinra.]]
*** Zack didn't acquire an official last name until he got his own game ''CrisisCore''.
*** Numerous characters like Kunsel, Tseng, Rude, Reno, Elena, Bugenhagen, Palmer, Scarlet, Nanaki, Seto, Heidigger, Elfe, Fuhito, Biggs, Wedge, Jessie and so on are known only by one name, although given the pattern of first/last name with the major human characters, it's quite possible that many of the secondary characters' last or first names simply haven't been disclosed.
** The FinalFantasyTactics series mixes this up a bit. Most of the major characters like Ramza, Ezel, Marche, etc. have surnames, but everyone else does not. In ''FinalFantasyTacticsA2'', Luso Clemens is the only character (besides Ezel) who has a surname, but everyone else has only a first name or a nickname.
** [[spoiler:Frimelda Lotice, Ghi Yelgi, Al-Cid Margrace, and Syrenead Sie Hyskarias]]
** ''VideoGame/FinalFantasyX'' is the other extreme: No surnames in Spira! But hey, in a country where you can call your goth-child "Lulu", does it really matter? Tidus, who comes from a really BIG city hasn't got a last name either, but that's due to his name being an extreme case of "optional" (so extreme that other characters only refer to him as "You")
*** Members of the Ronso and Guado tribes have it as a surname, some of whom are related (Seymour Guado is Jyscal Guado's son), but it is never treated as such.
** For the most part, last names are never mentioned for [=PCs=] in ''FinalFantasy'' games. They may be listed in [[AllThereInTheManual supplemental material]], but they are never actually used in the games themselves.
** ''KingdomHearts'', finally, allowed the Disney Characters to keep their last names, but eliminated those of the FinalFantasy characters, save for Squall's surname, "Leonhart" --- it becomes his first name. The original KH-characters themselves are surname-less, like in FFX.
*** Squall is still known as such by some of the other characters in the games, and it's explained that he only goes by Leon because of some sort of tragedy and will go back to using Squall when his homeworld is back to normal. Why he didn't go back to Leon in ''[=KH2=]'' is another question altogether. (Probably since his homeworld isn't back to normal yet.)
** Odd that no mention is made of ''FinalFantasyVI'', wherein almost every major character has a last name. Terra Branford, Celes Chere, Kefka Palazzo, and so on. Notable exceptions would be the Esper race, who have only the one last name. Maduin, Ramuh, Shiva, etc.
** The series of characters known as "Cid". Excluding the ones in the [[VideoGame/FinalFantasyI first]], [[VideoGame/FinalFantasyII second]], tenth, and [[VideoGame/FinalFantasyXI eleventh]] games, most Cids have full names. There's Cid Haze (''[[VideoGame/FinalFantasyIII III]]''), Cid Pollendina (''IV''), Cid Previa (''[[VideoGame/FinalFantasyV V]]''), Cid Del Norte Marquez (''VI''), Cid Highwind (''VII''), Cid Kramer (''[[VideoGame/FinalFantasyVIII VIII]]''), Cid Fabool IX (''[[VideoGame/FinalFantasyIX IX]]''), Cidolfas Demen Bunansa (''[[VideoGame/FinalFantasyXII XII]]''), Cid Raines (''[[VideoGame/FinalFantasyXIII XIII]]''), and Cid nan Garlond (''[[VideoGame/FinalFantasyXIV XIV]]''). A few notable Cids from the spin-offs have their own full names too, like Cidolfus Orlandeau.
* Trolls in ''VideoGame/{{Warcraft}}'' games supposedly only have one name, with possibly the name of their tribe added (for example Vol'jin of the Darskspear tribe), but this is contradicted by many troll [=NPC=]s having a last name.
** The vast majority of draenei don't seem to have last names either. However, they seem to make up for it with titles (paladins are "Vindicator [Insert Name]," for example) and sobriquets (such as "Stormglory").
** Also the vrykul, who sometimes get titles to go with their names (Svala, the first boss of Utgarde Keep, is turned into a Valkyr and dubbed "Svala Sorrowgrave" by the Lich King)
** For that matter, orcs in Warcraft lore generally only have one name. They'll identify themselves by IAmXSonOfY, but it's supposed to be very rare for the to earn sobriquets. Sobriquets do get passed down family lines, but only upon death and only to one descendant(There's only ever one Hellscream or Doomhammer at a time), and it's possible for an orc who inherited their sobriquet to earn a different one. Still, the majority of them fall under this trope; even one of their most iconic heroes, Thrall, hasn't been given a sobriquet.
* Eisen and Inori of the original ''HarukanaruTokiNoNakaDe'' are examples of this, for different reasons: Eisen is a monk and the emperor's half-brother, while Inori lacks a family name on the account of his low origins -- justified by the fact that [[TrappedInAnotherWorld Kyou]] is based off [[JidaiGeki Heian Period Japan]], so those who ''do'' possess family names are either of noble origins or from our world. On the other hand, the Oni don't appear to have last names either.
* In ''StarCraft'', the Protoss and Zerg have only one name, such as Aldaris, Tassadar, Zeratul, and Zasz.
** Given that the Zerg are a HiveMind, there's no need for names at all, the Cerebrates are the only ones who can even be called individuals in the Swarm, except for the Overmind. There can't be enough Cerebrates to warrant last names.
* Most [=NPC=]s in the ''VideoGame/{{Diablo}}'' games don't have both a first and last name. Deckard Cain, Zoltun Kulle, and Haedrig Eamon are some of the few exceptions.
* In ''VideoGame/ValkyriaChronicles'', your Darcsen allies are only known by their given names (Wavy, Nadine, Zaka, etc.) Isara is an exception; while she is Darcsen by birth, she was adopted by Welkin's father, and was given his last name of "Gunther".
* ''SpaceChannel5'' does this. We have Ulala, Pudding, Jaguar, Purge... I could go on, but I won't.
* Most of the antagonists in ''VideoGame/{{Xenosaga}}'' have only one name: Margulis, Pelegri, Wilhelm, Sellers, Sergius, and Heinlein.
* [[GadgeteerGenius Maximilian]], aka Max, one of the protaginist of ''VideoGame/DarkChronicle''. The other, [[ActionGirl Monica Raybrant]], averts this trope.
* Almost everyone in the ''JakAndDaxter'' series, to the point that the only full names given are either AllThereInTheManual (Samos and Keira Hagai, though the canon-ness of this is contested) or most likely a joke (Ozmar Itchy Drawers the Third). The only ones who definitely have a last name are Gol and Maia Acheron.
* "[[VideoGame/RatchetAndClank Ratchet]]". And that's it. Sort-of-justified by him [[ParentalAbandonment not knowing his real parents]]. Or would that be "[[EveryoneCallsHimBarkeep Everyone Calls Him Ratchet]]" instead? "Clank" is also an example, it was even made up on-screen (the Future Trilogy confirms his real name as [[spoiler: XJ-0461]]).
** According to [[VideoGame/RatchetAndClankFutureToolsOfDestruction Tachyon]], "Ratchet" is not even his real name.
* Ben, the player character in ''FullThrottle'', is only ever called just Ben, and prefers to keep his last name a secret. The same goes for Maureen, although you do find out her full name very soon after meeting her: [[spoiler:Maureen Corley.]]
* Many characters in ''JadeEmpire'' have only one name and a title, and the few that do not are usually related to another NPC. (For example, Kia Min, a student in Chapter 1, is the niece of a merchant in the Lotus Assassin fortress).
* [[MysticalWaif Anne]] and [[FairyCompanion Piko]] in ''VideoGame/MitsumeteKnight'' ; and all characters save for [[TheHero Christopher [=MacLeod=]]] in ''Mitsumete Knight R : Daibouken Hen''.
* Tomomi in the ''TokimekiMemorial'' series; she's notable for being the sole case of this in ''the whole franchise''.
* Many ''VideoGame/{{Touhou}}'' characters, the most famous being Cirno. The vast majority are in the {{Ret Con}}ned PC-98 games though, so it could be attributed to EarlyInstallmentWeirdness, until both ''Undefined Fantastic Object'' and ''Double Dealing Character'' added two examples each.
* ''VideoGame/CaveStory'' features multiple characters with only one referred name. The list includes, but is not limited to [[TheSilentBob Quote]], [[GlassCannon King]], [[FriendlyEnemy Balrog]], [[WickedWitch Misery]], and [[MadScientist The Doctor]]. Don't get us started about many of the other [=NPC=]s.
* The 1993 EdutainmentGame ''EagleEyeMysteries'' gives us minor character Sergio, who declares he is like Madonna and Cher and has no last name, when asked on one occasion. This causes another character, Silvia Torres, to suspect him in a later mystery of being a criminal and the mystery's guilty party. [[spoiler:He's innocent]].
* In the ''VideoGame/MetalGearSolid'' series we have David (Solid Snake), John (Naked Snake/Big Boss), Adamska (Revolver Ocelot), Jack (Raiden), Rosemary, Mei-Ling, Dr. Clark (Para-Medic), Jonathan (two of them), Ed and Johnny (after his surname "Sasaki" was retconned out of existence). That's not even counting characters who are known primarily by their one-word codenames like EVA and Vamp.
* ''In general'', Japanese adaptations of ''RomanceOfTheThreeKingdoms'' would have a translation convention which would cause this trope. To prevent NamesTheSame issues when people are on LastNameBasis--Chinese surnames are short, often homophonous, and are relatively few--the characters' first and last names would be mashed together and treated as if it was a last name. For example, Liu Bei (Bei of the Liu family) would be call Ryuubi (not Ryuu Bi as it should be), and when Japanese etiquette requires LastNameBasis, he would be called Ryuubi-san, rather than Ryuu-san. No, the naming convention in ''IkkiTousen'' wasn't an invention but rather a existing convention.
** They will also refer the characters by their courtesy names (a unique name given later in life according to Chinese tradition). For example, Zhuge Liang is usually referred to as 'Konmin', a Japanese rendition of Kongming, Zhuge Liang's courtesy name.
* [[VideoGame/MegaMan Rock]], Roll, and Blues, as well as Bass in the original generation, and Axl and the Navigators Alia, Pallette, and Layer in the ''VideoGame/MegaManX'' series. The titular character is Mega Man X, and his teammate is Zero Omega. Also most of the characters in the ''VideoGame/MegaManZero'' and ''VideoGame/MegaManZX'' series.
* None of the characters from ''VideoGame/GhostTrick'' are given two names, thus leaving it unclear in many cases whether people are being referred to by their first name or last name.
* {{Parodied}} in ''[[LEGOAdaptationGame Lego Batman 2]]'', where a receptionist demands Batman's and Superman's names despite them being '''in full costume'''. Batman says he's only got one name (i.e. Batman), "like Madonna".
[[/folder]]

[[folder:Webcomics]]
* The angels in ''Webcomic/{{Misfile}}'' are on an OnlyOneName basis, probably related to how they [[OurAngelsAreDifferent come to exist]].
* In ''Webcomic/OzyAndMillie'', Ozy's (adoptive) father is simply known as Llewellyn. His son Ozy inherits the name as a family name. Millie's mother has always been referred to as simply "Ms. Mudd", and her first name was never revealed to the readers until [[http://ozyandmillie.org/2008/10/01/ozy-and-millie-2114/ this]] strip came out.
* ''[[http://www.jaydenandcrusader.com Jayden and Crusader]]'' has a fair few of these, Third, Smic and Crusader. Crusader is the more interesting one, because he was called Crusader and had been called Mr. Crusader by some, until we eventually found he was called Crusader Crusader. Effectively having only one name, as first and last name is the same.
* ''Webcomic/ElGoonishShive'' didn't reveal Sarah's last name (Brown) until 2007. When they ''did'' give Sarah's name, it was a casual toss-out (the principal was yelling at her).
** Recently we've met Mr. Verres' mentor, "Arthur J. Arthur". WordOfGod has it that the J stands for "Just".
* The main character of ''Webcomic/TooMuchInformation'', Ace, legally has no last name.
* Sabrina and her family in ''WebComic/SabrinaOnline'' never had their surname revealed, though some fan fiction has tried to do the job for the strip ("Mustelidae").
* ''Webcomic/QueenOfWands'' never mentions the last names of its characters, though ''Webcomic/SomethingPositive'' does. Kestrel from ''[=QoW=]'' wound up becoming a recurring character in ''S*P'', but still has no last name, which is [[LampshadeHanging Lampshaded]] on the cast page.
* ''Webcomic/GunnerkriggCourt'': Jones "[[http://www.gunnerkrigg.com/archive_page.php?comicID=367 Just Jones will do]]". [[WordOfGod Word of Tom]] [[http://www.formspring.me/gunnerkrigg/q/261930246 confirms]] that Jones is her full name.
* ''Webcomic/FallCityBlues'': Everyone.
* ''Webcomic/SlightlyDamned'': Demons and Jakkai generally only have one name, though Jakkai tend to use nicknames as a psuedo family name.
* ''Webcomic/{{Pibgorn}}'': [[http://www.gocomics.com/pibgorn/2007/03/09/ Thorax never asked whether Thorax was his personal or family name; he doesn't like to pry.]]
* Members of the ''Webcomic/VoodooWalrus'' cast all started off sporting simply one name, but as time and the story have progressed, full names have been revealed. Bowler, Shmeerm, Mirth, and Marron seem to be the only major characters left without last names.
** Its actually been hinted at that Bowler and Mirth are both going by aliases. Its suggested Bowler has a different name [[http://voodoowalrus.com/?p=29 here]], and its unknown whether or not Mirth's father was just joking [[http://voodoowalrus.com/?p=980 here]].
* Mori of ''Webcomic/TheDragonDoctors'' has only one name because her family's name was destroyed with magic. She doesn't remember it and it's vanished from all documents.
* ''Webcomic/TheOtherGreyMeat'': Almost every character in the story only has one name. People with last names are typically only those who are referenced before the ''ZombieApocalypse''.
* ''Webcomic/NoSongsForTheDead'': The main character Hector, Romeo, the ''BigBad'' Lilith.
* Jack from ''Webcomic/{{Mulberry}}'' has no last name, unlike leading ladies Mulberry Sharona and Taffeta "Taffy" Sparks. The latter didn't have a last name, either, until a SuddenNameChange from "Tiff" to "Taffy".
* Fred from ''Webcomic/{{Namesake}}'' was a generic [[AliceAllusion card soldier]] before a half-asleep Elaine decided she needed to call him ''something''. She made up a single syllable based on his title (the Five of Hearts -> Five-Red -> Fred). This would be a case of OnlyKnownByTheirNickname - except, given the immense power that names have in this particular comic, being granted a name plus Elaine's wish for them to "understand each other" slowly changes him from a blank-faced watchdog into something entirely different. A couple of volumes later, Fred is an empathetic, genuinely adorable character with a growing number of human traits (including hair, blood and a fierce affection for Elaine herself). He quite literally only needed one name to become that. Efficient.

[[folder:Web Originals]]
* Alex Kralie is the only character from ''WebVideo/MarbleHornets'' with a known last name. The one time Jay (the narrator) mentions his last name to someone, he mutes it on the Youtube video. When he finds some medical records of Tim's, someone has scribbled over ''his'' last name except for the first letter (W).
* Corbin and Desmond from ''WebVideo/SplinterCellExtinction''. Desmond's surname is always left out of the frame, and "Corbin" is either the protagonist's given name or code name (judging from the fact he's apparently on FirstNameBasis with his MissionControl).
* In Machinima/RedVsBlue, there are a number of dumb AIs (dumb in the sense of less advanced, not stupid) with only one name--Sheila the tank, Lopez the robot mechanic, and Andy the bomb. Vic is actually an example of EveryoneCallsHimBarkeep--"VIC" stands for Virtual Intelligence Computer. The Freelancer AIs ([[spoiler:and the full smart AI they were fragmented from]]) are also known by just one name, a letter from the Greek alphabet.
[[/folder]]

[[folder:Western Animation]]
* In ''WesternAnimation/AvatarTheLastAirbender'', Toph Beifong, her father Lao, and her mother Poppy are the only characters to possess a surname. This itself isn't too far off with the traditional Asian theme of the series, in that traditionally, in East Asian cultures, family names were reserved exclusively for members of high nobility, much like the wealthy Beifong family, before common people started adopting family names for themselves. Alternatively, this may be due to the Anglicisation all of the names have undergone, which can be seen when comparing the names given to the Chinese characters occasionally used to spell them. An Ang as written, for example, is rendered as Aang when spoken, and Ai Luo becomes Iroh. In case you're wondering, yes that's probably how they made their names.
** In SequelSeries ''WesternAnimation/TheLegendOfKorra'', surnames are likewise rare. Lin Beifong, daughter of Toph, has one. Hiroshi Sato and his daughter Asami also have last names. They're rich, but not from nobility, as Hiroshi was stated to be a SelfMadeMan. [[FictionalSport Pro-Bending]] CombatCommentator Shiro Shinobi also has one.
* The naming conventions of the ''Franchise/{{Transformers}}'' tend towards one-word names, like Dirge, Cliffjumper, or Rattrap. Two-word names such as Optimus Prime, Ultra Magnus, or Nemesis Breaker, aren't uncommon, but rarely is the second word treated as a surname. (Think of it as akin to some people in the southern United States bearing double first names such as Billy Bob or Rita Mae. Optimus Prime is called simply "Prime" fairly often, but that's because it's a title like "Captain".) Transformers with names of three or more words are EXCEEDINGLY uncommon, and generally only in Japanese continuity.
** However, being robots who routinely re-use identical bodies, names, and color schemes, this is probably not a big concern.
* ''MyLittlePony'' follows roughly the same naming convention as ''Transformers''. On the odd occasion that we get the names of multiple members of pony families, they'll share a [[ThemeNaming theme,]] if that, with proper surnames being either unknown or unused. ''[[WesternAnimation/MyLittlePonyFriendshipIsMagic Friendship Is Magic]]'' has more two-part than one-part pony names, including just a few acting as surnames, but there are plenty of single-part names too, and non-ponies more often have single-part names (Spike, Discord, Zecora).
* Spoofed in an episode of ''WesternAnimation/CowAndChicken''. The Red Guy accuses Chicken's friend Flem of having [[EmbarrassingMiddleName a girl's name for a middle name]]. Flem protests "I don't have a middle name! I don't even have a last name! I'm just Flem!"
* "The Frying Game," an episode of ''WesternAnimation/TheSimpsons'' includes Lou the cop telling a reporter that he and Eddie (the other cop) have no last name "like Cher."
** In fact, a majority of recurring characters in Springfield, as well as certain one-time characters do not have last names, while some characters have their identities concealed be nicknames, honorifics, and occupational titles. If fact, many of the same recurring children of Springfield Elementary only have first names, while their full identities are never mention, possibly due to the negligence of the school staff and the writers.
** MattGroening wrote in a Simpsons comic "as far as I'm concerned, Lenny doesn't have a last name." It was later revealed to be [[RepetitiveName "Leonard" in order to correspond with Carl's "Carl Carlson."]]
* Timon and Pumbaa from ''Disney/TheLionKing'' were given last names, Berkowitz and Smith, respectively in ''WesternAnimation/TimonAndPumbaa'' (Nowadays, though, [[CanonDiscontinuity Disney pretends they weren't]].)
* ''WesternAnimation/FostersHomeForImaginaryFriends'' is an interesting case, everyone has only a first name, like Mac, or only a last name, like Mr Herriman. Only two main cast members are exceptions; Frankie has a last name by association (she's Madame Foster's Granddaughter, and her ID confirms her last name is Foster) and Bloo, because a 3-year-old Mac apparently though "Blooregard Q Kazoo" was a great name.
* Pickles the Drummer of ''{{Metalocalypse}}'' is the only member of the band without a last name of any kind.
** They even avert mentioning is surname when visiting his relatives in multiple episodes, but not to the point of lampshade hanging.
* ''TheBackyardigans''' title characters. Subverted during one episode, "Whodunit?" where Uniqua was Uniqua Underhood and Austin was Austin Frothingslosh. But you [[EmbarrassingMiddleName can't help but laugh at the latter's surname, just how stupid it is]].
* No character in Disney's ''Disney/BeautyAndTheBeast'' has more than one name.
** Very few Disney characters have both a first and last name. Almost everyone in ''Disney/{{Mulan}}'' has a family name, but that's an exception (and a somewhat necessary one, since Asian cultures use the surname far more than Westerners). Some of the name shortage is justified (Arabic names usually include a patronymic, so with ''Disney/{{Aladdin}}'' not knowing who his father is, he couldn't have one) and some of it isn't (why are princes with no family identifiers running around? Usually your family is the reason you're a prince in the first place...)
*** TruthInTelevision: Real princes don't use family names - they don't need to, at least in their own countries, their title and first given name is sufficient identification.
*** When he was in disguise as a prince, he took the name Ali a Babwa, with 'a Babwa' being his surname, but doesn't have a real surname that he knows of.
* Several characters on ''TheFairlyOddparents'' fall into this trope. The most obvious are Cosmo and Wanda. On the human side, we have Vicky, Tootie, Elmer, and Sanjay. Trixie Tang is the only member of [[RichBitch The Popular Kids]] to have a full name.
** Cosmo and Wanda's full names [[WordOfGod were revealed to be]] Cosmo Julius Cosma (thus why his mother is always called "Mama Cosma") and Wanda Venus Fairywinkle-Cosma, respectively.
* ''WesternAnimation/AnAmericanTail'' has Tiger and Bridget with only a first name, in a series that usually prides itself in coming up with creative [[SpeciesSurname Species Surnames]].
* Henry and June of ''KaBlam''.
* Dib from ''InvaderZim'' has no last name. Though many fans assume that it's simply "Membrane", as his father is called "Professor Membrane", but WordOfGod is that "Membrane" is his father's ''first'' name. However when the Meekrob tried to get his name right and called him "Dib...Dib...whatever your last name is..." Dib simply replied with "that's right."
* Everybody in ''WesternAnimation/WinxClub'', including Bloom and Roxy, who grew up on Earth and therefore [[NoNameGiven should have last names]]. Everyone else from the Magical Dimension identifies him- or herself by the realm they're from.
* [[MadScientist Heloise]], [[CrazyAwesome Saffi]], and [[RichBitch Jez]] from ''WesternAnimation/JimmyTwoShoes'' This seems to be a woman thing, as all the male characters have full name ([[ThePollyanna Jimmy Two-Shoes]], [[TheHedonist Beezy J. Heinous]], [[TheCaligula Lucius Heinous VII]], [[ButtMonkey Samy Garvin]]).
* Music/{{Gorillaz}} guitarist Noodle was created in a laboratory and apparently had no name at all until the other band members found her. They named her Noodle [[VerbalTicName because it was the only English word she knew]] at the time, and she still doesn't have a surname.
* In ''WesternAnimation/TheNightmareBeforeChristmas'', Sally has no last name, though fans usually give the last name of [[MadScientistsBeautifulDaughter Finklestein]], [[ExactlyWhatItSaysOnTheTin Ragdoll]], or in FanFics where she's married to Jack, Skellington.
* All of the ''WesternAnimation/{{Gargoyles}}'' have only one name, if they have a name at all. (As a species, they don't use personal names. Since this makes dealing with humans in the modern era difficult, to say the least, they choose them for purposes of identification.)
* The titular character of ''HeyArnold'' was never given a last name. He even won a contest once and when the announcer said he couldn't read the last name Stinky turned to Arnold and said it could only be him "on account of you being the only kid named Arnold in the whole school."
** WordOfGod says that his last name was Shortman, which is why his grandfather was always calling him short man.
* Most characters in ''ReBoot'' have only one name. Of the main cast only the Matrix's have last names, and Matrix wants everyone to forget he has a first name.
* While a number of ''WesternAnimation/{{Recess}}'' characters have their full names revealed, some characters lack a last name, such as King Bob, Butch, Francis (Hustler Kid), Jordan, Jerome, Cindy, Hector, Spencer, Emma, Sam, and Dave.
* Dan, Chris, and Elise of ''WesternAnimation/DanVs''. We even see Dan's driver's license and it just says "Dan".
** In one episode where we see Chris's drivers liscense it reveals that his last name is Pearson, after Chris Pearson (one of the Shows creators), and we can assume Elise took Chris's last name when he married her.
* ''{{WesternAnimation/Motorcity}}'' has the exceptions of Mike Chilton, Julie and Abraham Kane and Dutch and Dar Gordy. Chuck, Texas, Jacob, Tooley, Claire, Tennie and most of the main cast are only known by their first name.
* Lance and Ilana of ''{{Sym-Bionic Titan}}'' initially had Only One Name (the latter might have been due to nobility) been adopted the street surname "Lunis" when they came to Earth. Octus/Newton has two names, but neither is a surname[[note]]although since he poses as a family member of Lance and Ilana's, he might use the Lunis name as well[[/note]]. Most of the students of Sherman High have Only One Name, which the exception of Kimmy Meisner and Brandon Chase.
* ''{{Daria}}'' had [[OneSceneWonder memorable one-off character]] [[SpearCounterpart Luhrman]]. When [[TheSnarkKnight Daria]] asks if that's his first or last name, he emotionlessly asks "Does it matter?" Fans tend to assume it's his surname.
** [[ExtremeDoormat Stacy]] is never given a last name, though WordOfGod says it's Rowe. [[{{Goth}} Andrea]] never got one either, but she's a fairly minor character. {{Fanon}} tends to go with [[TheOmen Thorne]], [[DarknessVonGothickname Hecuba]] or [[TakeAThirdOption Thorne-Hecuba]].
* Larry (The Lobster) of ''WesternAnimation/SpongebobSquarepants'', even though all the other main characters (such as Patrick, Sandy, Squidward) were revealed to have last names eventually, while Krabs, Plankton and Mrs. Puff were eventually revealed to have first names.
* The majority of the characters in ''WesternAnimation/TotalDrama''.
-->When Sierra got temporarily married to Cody:
-->'''Chris''': Two votes for Sierra.
-->'''Sierra''': I'm sorry. My name is Sierra-Cody now. It's hyphenated.
** Ironically, Sierra herself revealed Cody's full name to be Cody Emmett Jameson Anderson.
** Other exceptions include Chris ([=McLean=]), Harold ([=McGrady=]), D(evon).J(oseph), Alejandro (Burromuerto), Dakota (Milton), Cameron (Corduroy Wilkins), (Mildred) Blaineley {Stacy Andrews O'Halloran) and Anne Maria.
* In ''WesternAnimation/AdventuresOfTheGalaxyRangers'', Niko doesn't use a surname, and doesn't appear to have biological family. Her mentor, Ariel, is the same. The Kiwi species (a culture of {{Badass}} {{Hobbits}}) also appear not to use surnames.
* Rocko from ''WesternAnimation/RockosModernLife'' is the only main character who's last name was never revealed on the show. When he appeared on a game show, the host, when introducing him simply stated "Rocko... no last name given." [[WordOfGod an early model sheet reveals it to be "Rama".]]
* In ''{{WesternAnimation/Ewoks}}'', aside from the Warricks, no other characters' last names are known, implying that they don't have any.
* ThePowerpuffGirls technically have last names, due to being Professor Utonium's daughters, but this is never acknowledged in any official media.
** Similarly, the Professor isn't given a first name.

[[folder:Real Life]]
* In real life, surnames are an invention that never really caught on in Iceland. In short, most people in Iceland are known by their given names, and they have a patronymic (or occasionally a matronymic) for disambiguation between individuals. The telephone directory is alphabetized in order of first name. For the full details, see Wikipedia's article "[[http://en.wikipedia.org/wiki/Icelandic_name Icelandic name]]".
** Patronymic and surnames do have a bit of overlap. That's where we get the surname Johnsson. But in places like Iceland, you only have that name if your father was named John.
*** And only if you're a man. If you're a woman you gets Johnsdóttir instead.
* It's quite similar in Mongolia, where family names are replaced by patronymic names.
* In Arab countries, traditionally, one's full name was *your name* *father's name* *grandfather's name* Al *clan name* [*Al *tribe name*]. Saudi Arabia, the Gulf countries, and a few others use this still, but when individuals spend an excessive time in the West (say for college/graduate school), they'll generally use the grandfather's name as their surname. In countries colonized by Europe where people were forced to take European style names, this pattern was also used.
* In Serbian history, last names were usually patronymic. For example, if a man's first name was Ivan, his children's last name would be Ivanovic. If a man was named Nemanja, his children's last name would be Nemanjic.
* Same was in Russia, where up to the 15th/16th centuries even the nobles mostly made do with bynames and {{patronymic}}s, and commoners started to acquire surnames in mass only after emancipation of the serfs in the late 19th century. Before that, only those living in cities would bother with it.
* Surnames didn't exist in Gaelic cultures for a long time. O' and Mc/Mac translate to "grandson of" and "son of", with female variations as needed.
* Another real-life example: [[Creator/MrT Mister T]] was born Lawrence Tureaud, but had his name legally changed. 'Mister' is now his first name.
** And wrestler [[Wrestling/UltimateWarrior Jim "Ultimate Warrior" Hellwig]] (of Wrestling/{{WWE}} fame and {{WCW}} infamy) has legally changed his name to "Warrior".
** So has Joanie Laurer, better known as Wrestling/{{Chyna}}. In both her and Warrior's case, it was an example of LoopholeAbuse. WWE trademarks wrestler's names, and wrestlers are forbidden from using them once they leave the company. However, they can't ban somebody from using their actual legal name, so they legally change them in order to do so.
* Indonesia (or more specifically, Java) is another culture where surnames are not universal. For example, two of the country's presidents (Sukarno and Suharto) only had one name.
** Sukarno and Suharto both adopted Islamic first names (Ahmed and Rahman, respectively) after making hajj.
** Even when there's a last name, it is often also a given name (not a family name/surname). An Indonesian can have more than five words in his/her name, all given ones. In Bali, [[http://en.wikipedia.org/wiki/Balinese_name your personal name comes third or fourth after a series of designations]] depending on your caste.
* In Burma, there also can be people with just one name. The Burmese Secretary General of the United Nations became known as U Thant, but U is just a honorific, like Mr.
** Burmese names are not just limited to one ''word''; modern names can usually have up to 3 or 4 syllable-words, and if the name is a bit long, some might cut down on a couple of syllables to make a shortened version or a nickname.[[note]]Shortening a name or nicknaming isn't generally considered rude in Burma if you've acquainted decently with the person.[[/note]]
* In Brazil, soccer players are usually known by a single name � which can be their given name (Neymar, Romário, Marta), a diminutive form of it (Robinho, Marquinhos, Edinho), a nickname (Pelé, Garrincha, Kaká), and more rarely a family name (Barbosa, Zagallo). A given name plus a nickname is also common, but very few players are known by their full name.
** This convention isn't restricted to soccer in Brazil. Most volleyball players, especially men, are also known by a single name. Mononyms are less universal in basketball, but can also be found�Oscar Schmidt and Hortência Marcari, both members of the Naismith Memorial Basketball Hall of Fame, are universally known in Brazil by only their first names, and after the player born Maybyner Rodney Hilário made it to the NBA, he legally changed his name to his longtime nickname of Nenê.
* An old joke revolves around this: Schwarzenegger has a long one, Richard Gere has a short one, Cher doesn't have one, and the Pope has one but never uses it. What is it? Given this article, it is obviously: [[spoiler:a last name]].
* Raymond Joseph Teller from Creator/PennAndTeller legally changed his name to Teller.
* Cher's full name was Cherylinn Sarkisian until she legally changed it to her single name.
* Japanese UsefulNotes/{{baseball}} star Ichiro Suzuki is widely referred to as just "Ichiro" in both Japan and North America, although he retains his family name for legal purposes. His Japanese Wikipedia article is titled "イチロー" (romanized as ''Ichirō'') rather than his full Japanese name of 鈴木 一朗 (''Suzuki Ichirō'').
* Radio talk show host "Lionel". "Mononymous, like God," he says. It isn't either of his real names, though.
* Renaissance artists often fall into this. Have you ever heard of the painters Sanzio, Buonarroti or van Rijn? Yes, you have. [[spoiler: Their first names are Raphael, Michelangelo and Rembrandt, respectively.]]
** And the most famous example: when referring to Leonardo, using 'da Vinci' only is incorrect because it's not his surname (it means 'from the town of Vinci'). 'Leonardo' and 'Leonardo da Vinci' are the only 'right' ways to refer to him, because he didn't have a surname.
* Traditional Hebrews did not use last names; they would personally identify themselves with a single name (considered as a first name) and their immediate heritage.
** This became a problem when turn-of-the-century Germany and Russia required first ''and'' last names in censuses. Often the families taking the census would simply spit out a common last name that they had no actual affiliation with. This is why many European Jewish families have traditional Germanic and Slavic last names.
** In the same vein, when the Spanish crown exiled all of the Jews (15th/16th century), they gave them a choice: to become Catholics and stay or to keep their religion and go. Some people stayed in Spain, changed to Catholics and got new names from [[LineOfSightName the first thing that came to their minds]], like Flores ("flowers"), Mesa ("table"), Barriga ("belly") or Cabeza ("head"). If you have a name like this, you probably have a ''converso'' ancestor.
*** Among the Portuguese ''conversos'' there was a tradition to adopt plants' names as their new Christian surnames. The popular Portuguese surname Pereira ("pear tree") is but one of them.
* Dido, formerly Florian Cloud de Bounevialle Armstrong.
* {{Lights}} (formerly Valerie Anne Poxleitner, although she still has the last name)
* ''Everyone'' in the credits for the first ''Film/BellaDancerella'' DVD "Let's Dance!" is listed only on a first-name basis, crew included.
* Most pets and named livestock have only one name, although vets sometimes append the human owner's surname for ease of record-keeping.
* Two Disney actresses, Lalaine Vergara-Paras and Creator/ZendayaColeman, are credited as just Lalaine and Zendaya respectively.
* In French-speaking countries it is a quite common phenomenon for people working in the arts and literature to use made-up names of this type, e. g. playwright Creator/{{Moliere}} (born Jean-Baptiste Poquelin), writer and philosopher Creator/{{Voltaire}} (Francois-Marie Arouet), novelist Creator/{{Stendhal}} (Henri Beyle), the architect Le Corbusier (Charles-Edouard Jeanneret-Gris), actors Fernandel (Fernand-Joseph-Désiré Contadin), Arletty (Léonie Bathiat), Bourvil (André-Zacharie Raimbourg), and Capucine (Germaine Lefebvre), and comics artists Moebius (Jean Henri Gaston Giraud), Morris (Maurice De Bevere) and Tibet (Gilbert Gascard). Among Francophone comics creators there is a particular fashion to use noms-de-plume that are phonetic representations of their initials, a fashion probably started by Hergé (Georges Rémi) that includes Achdé, Peyo, Jijé, Jidéem, etc. Marvano (Marc van Oppen) is a borderline case.
* Before people started making proper armies and the urbanization everyone had OnlyOneName. Last names where invented to stop 15 people show up whenever someone screamed 'Tom'; which gives us the poor imagination when it comes to some of the more common last names (Tom the Baker = Tom Baker; John the Smith = John Smith etcetera.)
** You can see this at work in the 1932 film ''MillionDollarLegs''. All the women in [[{{Ruritania}} Klopstockia]] are named Angela. All the men are George. Why? Why not?
* And now the Welsh, due to a shortage of distinct surnames, are repeating the process, to distinguish, e.g., Tom Jones the baker from Tom Jones the singer.
* Chukchi (Russian Eskimos) traditionally have only one name, but can add Russian names for census purposes, so their Chukchi name could be considered their truest name. For example the true name of Yuri Sergeyevich Rytkheu is simply Rytkheu ("unknown" in Chukchi). He added "Yuri Sergeyevich" when Soviet officials asked him to have a Russian-style name. Other one-name Chukchi include Tenevil (herdman who developed a crude writing system) and poetess (Antonina Alexandrovna) Kytymval.
* The nobles of the Heian era of Japan was only known by one name. Even then, those weren't even their real names. Surnames for the common folk in Japan were later introduced and were based after the person's occupation or the area they lived in.
** Japanese emperors have only one name, (Hirohito, Akihito, etc.) In Japan, calling emperors by their given name is considered disrespectful, so Akihito (the current emperor) is simply called "His Imperial Majesty the Emperor"; and Hirohito is called Emperor Shōwa, after the era he reigned.
* In Western Finland, only noble and bourgeoisie families had surnames before the 19th century. Others used house names, and patronymics may have been in use in some circles. In the Eastern Finland, however, surnames are a long tradition.
* Ancient Greece had no surname tradition whatsoever. Aristotle, Socrates, Pericles, Alexander (the Great/of Macedon) and Leonidas I were all surnameless. After Romans conquered Greece and started importing Greek slaves, any freed Greeks had to adopt the surname of their ex-owner since they lacked any of their own.
** Even then, the Romans themselves had a rather significant problem with the surnames, as they, just like Welsh, had about a dozen surnames (called "nomen gentile") for ''everyone'', and also weren't anymore imaginative with the given names either, so after they first (unsuccessfully) tried to distinguish thousands of various Gaiuses or Marcuses by their clan names, they had to adopt the special official nickname called "cognomen", and when these started to be inherited too, an ''another'' byname � the "agnomen". They'd probably soon ran out of them too, but by that time the Rome finally fell. It was so bad that most of the Emperors of the Juleo-Claudian dynasty had names that were ''almost exactly same'': Gaius Julius Caesar .
* Likewise, some rural Dutch didn't use surnames, or just used patronymic, occupation, or place names. When the French invaded, they started a census and demanded first and last names. The locals, annoyed at the conquering armies, started giving last names like Naaktgeboren ("Naked Born") and Piest ("to pee") to troll the census takers. You can still find these names in the phone books.
* Most Turks had no surname before 1934, when the they were required to adopt surnames as part of President Mustafa Kemal Atatürk's westernization and modernization campaign. His own last name, granted to him by the Turkish parliament, means "Father Turk".
* Akoni, a Seattle theater actor.
* Many North American tribesmen in the past didn't have surnames either.
