A character needs an alias for some reason and technically ''doesn't'' lie about what their name is... it might be their real name if they're known by a nickname or vice versa, or their maiden name if they're a married woman, or their middle name being used as their first name, but the point is that the character can argue that it ''is'' their real name.

Often used by [[KingIncognito disguised royalty]] with {{overly long name}}s, since they can just pick one of their many middle names to be called by. One common variation is for a character to use [[NomDeMom their mother's maiden name as their surname]] in place of their father's.

See also MrSmith.

SueDonym is when the alias used is the real name, after a bit of distortion in pronunciation.



[[folder:Anime & Manga]]
* In ''Anime/{{Monster}}'', Nina Fortner uses her previous legal name, Anna Liebert, when giving a police testimony and obtaining marksmanship training.
* During ''Manga/RanmaOneHalf'''s [[MartialArtsAndCrafts Martial Arts Rhythmic Gymnastics]] competition, female Ranma freely gives her full name, confident that nobody in attendance (which includes classmates from Furinkan High) will make the connection with her male side. She's right, and everyone blows it off as a bizarre coincidence, although [[ThoseTwoGuys Hiroshi and Daisuke]] would constantly pester Ranma about introducing them to "his sister" afterwards. None of the matters either way, though, as (in the manga) they all found out shortly after and didn't really care.
* In ''Anime/CodeGeass'', the main character and his sister use their real first names and their mother's maiden name for their surname while hidden in Japan.
* In ''Manga/DeathNote'', Light Yagami expends a lot of effort trying to learn the real name of "L", the GreatDetective who opposes him. [[spoiler: It's eventually revealed (although [[AllThereInTheManual not in the manga or anime]]) that L is his ''real'' first name, although Light still didn't know his last one, so this wouldn't have made a difference.]]
* A plot point in ''LightNovel/{{Baccano}}'' is that immortals cannot use aliases in the presence of each other: they are always forced to reveal their true names. [[spoiler:Fermet gets around this rule by using portions of his full name as aliases]].
* A weird version occurs in ''LightNovel/ItsukaTenmaNoKuroUsagi'': the vampire サイトヒメア (Saitohimea) takes on the name 沙糸 ヒメア (Saito Himea, Saito being the surname) when attending school with Taito. Though it's technically less of an alias and more of a necessity to have a Japanese name.
* ''LightNovel/SwordArtOnline'': Asuna Yuuki just went with Asuna in ''Sword Art Online'' due to being new to MMO games, and not realizing the game was asking for an alias to use in game. It's not until the restored ''[=ALfheim=] Online'' that she creates a Sylph alt character named Erika, but still primarily plays as an Undine, still named Asuna.

[[folder:Comic Books]]
* Franchise/{{Batman}}'s butler Alfred Pennyworth has sometimes used his middle names, Thaddeus Crane, as an alias when undertaking some activity he doesn't want linked to Bruce Wayne.
* ''ComicBook/XMen'':
** ''ComicBook/TheDarkPhoenixSaga'' sees Jean Grey being seduced by a mutant named Jason Wyngarde, an aspiring member of the Hellfire Club. It turns out Wyngarde was one of their older and [[AscendedExtra slightly more obscure enemies]], the mutant villain Mastermind, and the ComicBook/XMen just never found out his real name. Although he was also a MasterOfIllusion, and thus was also able to disguise himself.
** Similarly, ComicBook/{{Mystique}} often posed as a secret service agent named Raven Darkholme in her early days. Turns out that's her real name. Amusingly, the AnimatedAdaptation of ComicBook/DaysOfFuturePast (with some of Bishop's future thrown in) has a woman looking just like the Raven Darkholme identity, whom Mystique copied, tied up, but ''deliberately left alive'' to be a witness to "Gambit" assassinating Senator Kelly. Presumably, this came before the revelation in the comics that Mystique was the "real" Raven Darkholme.
** Bishop at one point in the early noughties posed as an Australian police officer under the name "Lucas Bishop," commenting offhandedly in his internal monologue "the name is real, the badge is not." This was TheReveal of his name after over a decade, with "Bishop" having generally been assumed to be an alias.
* ComicBook/SpiderMan was cloned, and the clone retained all of Peter's memories, to the point where he originally believed that he was the real one. Eventually the cloned Peter takes the name [[ComicBook/ScarletSpider Ben Reilly]], derived from Peter's middle name and Aunt May's maiden name (which helps facilitate the story that the two are [[StrongFamilyResemblance oddly identical]] cousins, as long as [[FridgeLogic no-one thinks too closely]] about Peter and May's actual relationship).

[[folder:Fan Works]]
* ''FanFic/PoniesOfOlympus'': Trixie enters the Atlas Strongest Tournament in a disguise and under her last name Lulamoon. Twilight recognizes her at the end of her match anyway.
* In the ''Literature/{{Discworld}}'' fanfic [[http://archiveofourown.org/works/241889 "The Brain Thief"]], Samuel Ramkin Vimes, Viscount of Oxbury and heir to the Duke of Ankh, introduces himself to a girl he meets as Sam Ramkin, thinking "It wasn't, technically, a lie." The girl, meanwhile, is studying midwifery at the Free Hospital as Meg Garlick, rather than Princess Esmeralda Margaret Note Spelling of Lancre ("Garlick" being her mother's maiden name).
* In ''Fanfic/TheMysteriousCaseOfNeelixsLungs'', Seska uses her real surname while undercover as a Bajoran for the Obsidian Order. After being outed she says her real given name's Jiana, not Harani.
* Fanfic/ACrownOfStars: [[spoiler: Chapter 74 reveals that Gendo had snuck into the Army Asuka and Shinji lead back to Earth, using his birth name of Rokubungi as an alias.]]

[[folder:Films -- Live-Action]]
* ''Franchise/StarWars'':
** When pretending to be a handmaiden in ''Film/ThePhantomMenace'', Queen Amidala used her lesser-known non-royal name, Padme Naberrie.
** Done by Obi-Wan Kenobi in ''Film/ANewHope'', using his real last name, and the nickname "Ben".
* John [=McClane=]'s wife at the beginning of ''Film/DieHard'' uses her maiden name, Gennaro. This provides a minor plot point when [[BigBad Hans Gruber]] later discovers John's real name, and doesn't realize the connection between John and Holly (for a while, anyway).
* In 1937's ''Film/ShallWeDance'', the two leads, who are both famous under stage names, get married quietly in [[{{Joisey}} New Jersey]] under their real names.
* The Disney Channel movie ''Motocrossed'' involved a girl posing as her brother to enter a motocross race, after he breaks his leg. The siblings have the same name (Andy, short for both Andrea and Andrew), allowing her a legal loophole: since she signed up as "Andy," instead of Andrew or Andrea, she could hold on to her win after she was outed.
* Vicki Lester and Norman Maine in ''Film/AStarIsBorn'' get married under their real names by a town clerk who has no idea who they are.
* Film/JamesBond does this quite often, though there are several occasions he uses proper aliases too. Somewhat justified in that officially he is a globetrotting employee for something called Universal Exports, which is actually a cover for [=MI6=]. In ''Film/TomorrowNeverDies'' he poses as a banker named James Bond and actually has a fake employment record, but is given away as a spy because it is too perfect to be true, and because he is asking too many questions, not because of his name. Of course, making a number of blatant references about the BigBad's actions ''to his face'' doesn't help his case...
* A very important plot point in ''Film/DefinitelyMaybe''. TheHero's daughter insists that he tells the story about how he met her mother whom he is now divorced. While doing so, TheHero calls his exes by alternate names to conceal their identity from his daughter who knows her mother's real name. [[spoiler: The daughter then realizes that her dad is still in love with April, one of his exes, because he didn't gave her a CodeName.]]
* Played with by way of a CastingGag in ''Film/ToTheLimit''. Secret agent "Collette Dubois" (Anna Nicole Smith) explains at the very end of the film that she's been using a codename the whole time, and that her real name is "Vickie Lynn" -- Smith's first and middle names in RealLife. In other words, Smith used (two-thirds of) her real name as a ''fictional'' alias.
* ''Film/TimeAfterTime'' deals with a visit by Creator/HGWells to the present. Initially, Wells, who assumed that Sir Arthur Doyle's little amusements would have been forgotten in 100 years, uses the alias Franchise/SherlockHolmes, only to get laughed at. In the end, he realises that while he is still remembered as an author, no-one remembers what his initials stand for, and that his name is unremarkable enough to not be immediately associated with the presumed long-dead author, so he goes by Herbert George Wells.
* The plot of ''Film/USMarshals'' kicks off when police discover that tow-truck driver Mark Warren is actually a fugitive named Mark Roberts. [[spoiler:And much later it's uncovered that Mark Roberts is actually burned DSS agent Mark ''Sheridan''.]]

* In Katharine Kerr's ''Literature/{{Deverry}}'' novels, the character Nevyn (meaning "no one", and hence often taken to be a joke) uses his long-abandoned original name (Galrion) when he needs to be taken seriously by some nobles. Everyone who knows him assumes he just made it up.
* In Creator/RobertAHeinlein's ''Literature/{{Friday}}'', the title character runs out of fake passports and falls back on the real one to pull a switcheroo with one of the fake [=IDs=].
* [[Literature/LordPeterWimsey Lord Peter Death Bredon Wimsey]] uses the name Death Bredon in the Creator/DorothyLSayers novel ''Murder Must Advertise'' and the short story "The Bibulous Business of a Matter of Taste".
* ''Literature/TheBelgariad'':
** In ''Belgarath the Sorcerer'', the eponymous character once uses his old name Garath when working undercover. It lasts until he has to use magic to fend off an attack.
** As well, his daughter Polgara sometimes goes as the Duchess of Erat, a title she technically owns although the duchy itself has been gone for thousands of years.
** After several centuries of mothers naming their daughters after the "legendary" Polgara, the real one can get away with just calling herself Pol.
* In ''The Truth-Teller's Tale'', members of the royal family have secret names that no one outside the family knows. A prince in disguise uses his as an alias. The narrator is a Truth-Teller, who [[LivingLieDetector can detect when someone is lying]], but since it's technically the prince's real name, she doesn't register that as a lie.
* The Creator/LMMontgomery short story "The Pot and the Kettle" combines a double use of this with a TwoPersonLoveTriangle.
* In ''Literature/TheOrdinaryPrincess'', Princess Amethyst works as a kitchen maid under her nickname, Amy. [[spoiler:The king of the kingdom she's working in does the same thing--she knows the king's name is Algernon, but he uses one of his many middle names.]]
* In ''How Not to Spend Your Senior Year'', when Jo and her father fake their deaths and go into witness protection, she uses her middle name and her mother's maiden name to enroll at another school. When the federal marshals who put them in witness protection want her to use a completely fake name, Jo tells them about an incident when she and a friend switched names as a prank on a substitute teacher and couldn't pull it off because they weren't used to responding to someone else's name.
* In ''The Goose Girl'', the princess' full name is Anidori-Kiladra Talianna Isilee. When she goes into hiding, she calls herself Isi.
* The prince in Sherwood Smith's ''A Posse of Princesses''.
* ''Literature/VorkosiganSaga'': Miles Naismith Vorkosigan spent ten years running top secret operations under the cover identity of Admiral Miles Naismith. Once, on the point of being found out, he covered by pretending that "Admiral Naismith" was his clone, who used his Betan mother's maiden name because Betan law grants clones the legal status of family members.
* In ''Spindle's End'', when Katriona and Aunt take in the little princess, they take the last of her many names, Briar-Rose, and decide to call her Rosie.
* In ''Literature/SixteenThirtyTwo'', King Gustav II Adolf of Sweden decides to send cavalry to help out his time-displaced American allies, and despite the misgivings of his prime minister puts the 'notably headstrong and reckless' Captain Gars in command. It's only after Gars helps save the Americans from an attack that it's explained to them that his name is an acronym for '''G'''ustavus '''A'''dolphus '''R'''ex '''S'''ueciae -- 'Gustav Adolf the King of the Swedes' in Latin.
* ''Discworld/MonstrousRegiment'':
** A regiment composed of [[SweetPollyOliver women dressed up as men]] dress up as washerwomen to get themselves into a fort, and use their real names as their aliases.
** Prince Heinrich of Zlobenia claims to be Captain Hortenz when captured. It's been speculated by fans that he has a ''lot'' of middle names, and is pulling the same trick as King Gustav, above.
* In ''The Birthday Ball'', Princess Patricia Priscilla dresses as a peasant and goes to the village school. When the schoolmaster asks for her name, she calls herself Pat. ("Quite a short name because I'm [[MostDefinitelyNotAVillain merely a humble peasant]].")
* In ''Literature/TheCountOfMonteCristo'', the aristocrat-born radical Nortier de Vilefort just goes by the name Nortier. In contrast, his conservative son calls himself de Vilefort. This is plot important, as the direct reason Dantes ended up wrongfully imprisoned is because he unknowingly told de Vilefort about a letter that incriminated Nortier for treason.
* In Creator/AndreNorton's ''Literature/ThePrinceCommands'', Michael uses this while passing himself off as the American friend of the prince.
* Creator/OrsonScottCard:
** In the sequels to ''Literature/EndersGame'', Ender simply goes by his given name of Andrew Wiggin. He is secretive about the fact that he's the same Andrew Wiggin who killed off the Bugger race thousands of years ago, but everyone thinks of that boy as "Ender," and the name "Andrew Wiggin" doesn't ring a bell for them. The few who do recognize the name assume his parents chose poorly when naming him.
** In ''Literature/{{Earthborn}}'', a character whose life has been greatly extended travels among people to whom she has become ShroudedInMyth. She uses her own name, and people assume her parents named her after the legendary figure.
* In ''Literature/TheDresdenFiles'', Harry Dresden goes undercover as Harry the technical assistant. It still fools [[spoiler: Lara Raith]] until he gets into a fight with Thomas. Harry, [[DeadpanSnarker being Harry]], points out [[PaperThinDisguise it really wasn't that hard to see through.]]
--> "You're Harry Dresden."\\
"Don't feel bad," I said, "I cleverly disguised myself as Harry the Production Assistant."
** The trope gets a sort-of inversion in the same book. One of the characters tries to frame Harry, but she's so vapid and shallow that she can't remember his name, telling the cops that his name was Larry. Or Barry.
* ''Literature/CodexAlera'', [[Creator/JimButcher by the same author]], has [[spoiler: Gaius Oc'''tavi'''an]]. And you thought the name was out of place amongst the AwesomeMcCoolname crowd.
** Tavi is named Tavar among the Canim. At first, he thinks it's a poor pronunciation of his name. Then it's revealed that a Tavar is the only hunter the Vord fear. It's a multilingual StealthPun.
* In the western novels of Creator/JTEdson, Dusty Fog frequently uses his middle names Edward Marsden as an alias, to the point that they become his GoToAlias.
* In ''Literature/UnnaturalIssue'', Lord Peter Almsley temporarily takes on the post of gamekeeper at the estate of his friends, with his valet Garrick as his scholar half-brother, in order to befriend Susanne (working as a dairy maid) and find out more about her. While in disguise, the two go by Peter Devlin (Devlin being Peter's middle name) and Clive Garrick (Clive being Garrick's).
* In ''Literature/CiaphasCain'' novel, ''For The Emperor'', Inquisitor Amberley Vail goes undercover as an entertainer named Amberley Vail. She also uses her real last name for two different undercover identities in ''Duty Calls'' -- the Lady haut Vail near the beginning of the novel, and Corporal Vail near the end. Possibly justified, in that anyone who can legally look at a roster of active Inquisitors already knows where she is and what she's doing, and she can kill anyone else who might blab.
* In ''Literature/{{Revival}}'', Charles Daniel Jacobs manages an impressive variety of combinations of real names as aliases.
* Emperor Andreas Komnenos in ''Literature/AnAgeOfMiracles'' goes by Andreas when he has to go incognito for a while. [[JustifiedTrope Justified]] by the fact that as a very popular emperor, he looks younger than most commoners his age and there are a lot of people named Andreas.

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'': When she runs away to LA, Buffy Summers calls herself "Anne," which is actually her middle name.

* Christopher Perry [[spoiler:Halliwell]] from ''Series/{{Charmed}}'' called himself "Chris Perry" when he first introduced himself. Since he's [[KidFromTheFuture from the future]] and hadn't been born yet, this didn't really raise any eyebrows.
* In ''Series/TheCosbyShow'', lawyer Clair once introduced herself by her maiden name in order to speak on son Theo's behalf when he got ripped off by a T-shirt company.
* In ''Series/{{Leverage}}'', Sophie Devereaux once had to conjure an alias from nowhere or risk losing the mark, so she introduces herself as the Duchess of Hanover. She assures the rest of the team that "this identity is very well backed up" but the mark isn't convinced. He arranges to introduce her to someone who's known the real Duchess for a very long time. While the rest of the team are convinced that Sophie's cover is blown, the Duchess's aunt takes one look at Sophie and says.... "Why Charlotte, it's so good to see you". It's never made clear if this is Sophie's real identity but it's the oldest one revealed on the show.
* In ''Series/BreakingTheCode'', the spook from "Security" is John Smith. He can never get anyone to believe that, yes, that IS his real name.
* In ''Series/SleepyHollow'', a captured [[spoiler:Hessian]] claims he knows everything about [[spoiler:Abbie Mills]], including her real name, [[spoiler:Grace Abigail Mills]].
* ''Series/LawAndOrderCriminalIntent'': In "Trophy Wine", a con man who has been living for years under the name 'Bing Cullen', rents an apartment under his original name Arnold Binder.

[[folder:Pro Wrestling]]
* In Wrestling/{{WWE}}, Shawn Michaels' mid-2009 absence was explained by him taking the job of a [[strike:[[LessEmbarrassingTerm cook]]]] chef at an office complex under the last name of Hickenbottom -- that being Michaels' real-life last name.

* In Shakespeare's ''Theatre/HenryV,'' King Henry goes undercover as a common soldier to learn the views and morale of his troops more closely. He gives his name to the soldier Pistol as "Harry Leroy" (Harry being a common nickname for Henry, and ''le Roi'' being French for "the King"). He says he's a Welshman, which is true, as he was born in Wales.

[[folder:Video Games]]
* Frank, the first NPC you meet in ''[[Website/GaiaOnline zOMG!]]'', is actually [[spoiler:Labtech 123]]; no official statement has been made, but the general assumption is that "Frank" is in fact his real name. Pretty much confirmed by one of the [=H2k10=] [=NPCs=], who has mentioned him by name.
* In ''VideoGame/TalesOfXillia2'', Gaius goes by "Erston" while [[KingIncognito traveling Elympios incognito]]. This is actually his birth name, while "Gaius" is an alias he assumed to protect his family from his enemies.
* ''VideoGame/TalesOfTheAbyss'': [[spoiler:Tear and Van's]] names are nicknames born from their full names - [[spoiler:Mystearica and Vandesdelca]] - and their last names are taken from their adoptive grandfather, successfully hiding their origin [[spoiler:as from Hod and Van's connection in particular]]. [[spoiler: Guy Cecil did something similar; his full name is ''Gai''lardia Galan Gardios and his mother's maiden name was ''Cecil''le.]]

* ''Webcomic/GirlGenius'':
** Gil is trying to get the attention of the crowd so that his father will know not to attack [[MalevolentArchitecture Castle Heterodyne]] while he's in there, but unfortunately they [[http://www.girlgeniusonline.com/comic.php?date=20081103#.VwZyifkrLIV don't seem to take his declaration]] that he's ''the'' Gilgamesh Wulfenbach seriously. He runs with it, pretending to be an actor pretending to be Gilgamesh Wulfenbach, and [[http://www.girlgeniusonline.com/comic.php?date=20081105#.VwZ0S_krLIU turns the whole thing into a massive performance]] and everyone thinks it's hilarious until he [[http://www.girlgeniusonline.com/comic.php?date=20081110#.VwZ01PkrLIU starts blowing things up.]] They still end up thinking it's a pretty good show, though, [[http://www.girlgeniusonline.com/comic.php?date=20081112#.VwZ1Q_krLIU especially after Zeetha joins in.]]
** A partial version occurs with Agatha -- when she's hiding from people who want to capture her because she's a Heterodyne, she hides out in a [[http://www.girlgeniusonline.com/comic.php?date=20041022#.VwZ6GfkrLIU Heterodyne show,]] playing the part of her mother while her love interest plays her father. She's [[http://www.girlgeniusonline.com/comic.php?date=20050511#.VwZ7oPkrLIU fully aware of the awkwardness.]]

[[folder:Web Original]]
* In ''Franchise/{{Noob}}'', WordOfGod states that Saphir's player is doing this (the actual reveal of the fact came out looking like a SuddenNameChange). She's using her middle name Pénélope for the public and her guildmates, but her real name is Elena. The reason for which she uses an alias has not been explicitly stated, but it may have something to do with her having a real-world job and social life when she requires her guild's new recruits to have neither of these to be able to be full-time players.
* ''Literature/WhateleyUniverse'':
** Jobe Wilkins is literally applying the trope, with his codename being Jobe Wilkins.

[[folder:Western Animation]]

* ''WesternAnimation/YoungJustice'':
** Artemis's real name is... Artemis Crock.
** Giovanni Zatara fights crime as the superhero... Zatara. Even his daughter, Zatanna, calls him that when she's referring to him specifically as a hero. When she takes up heroing permanently, she also goes by her given name.
* The ''WesternAnimation/TinyToonAdventures'' episode "Cinemaniacs!" has [=SuperBabs=] from the segment of the same name.
-->'''Hamton:''' I wonder who [=SuperBabs=] really is.\\

* In ''WesternAnimation/TeenageMutantNinjaTurtles2012,'' [[DaddysLittleVillain Karai]] cozies up to [[TheChick April]] using the fake name Harmony, a translation of [[spoiler:her birth name, Miwa]]. Played with, in that Karai [[spoiler:didn't know that Miwa was her real name]].

* ''WesternAnimation/WorldOfWinx'': [[spoiler:Jim is Captain ''James'' Hook]].
* ''WesternAnimation/TheSimpsons'': In the episode "New Kids on the Blech", when Lisa discovers Bart's boy band is part of a subliminal advertising campaign for the US Navy, their manager "L.T. Smash" turns out to actually be ''Lt.'' Smash. She discovers this because his real name was on a placard, [[RuleOfFunny which they altered by pasting on a speck of paper with a period]]. However, once this is revealed he formally introduces himself as "Lieutenant...L.T. Smash".
* This turned out to be the case in ''WesternAnimation/VoltronLegendaryDefender'', specifically the nickname version. It turns out that Pidge Gunderson's real name is Katie Holt, who entered Galaxy Garrison training under an assumed name (and [[WholesomeCrossdresser gender]]) to search for her missing brother Matt after getting banned from the base in her real identity. She chose Pidge as an alias because that's the nickname that Matt used to call her growing up.
* In ''WesternAnimation/SantaClausIsCominToTown,'' SantaClaus was a DoorstopBaby with a tag that said "Claus," but was adopted by [[ChristmasElves the Kringle family of elves]], who named him Kris. Later, when he becomes an outlaw (for the crime of making toys) he adopts his birth name to avoid detection.

[[folder:Real Life ]]
* British DJ Kenny Everett (real name Maurice Cole) once did a promo which ended with the words "... or my name isn't Maurice Cole!" The joke being that most of the listeners wouldn't have known his real name at the time.

** Another would be Creator/AngelinaJolie (Voight).
** Music/RayCharles (Robinson)[[note]]He dropped his last name at the start of his music career so people wouldn't confuse him with boxing great Sugar Ray Robinson, who was then in his prime. Ironically, "Ray Robinson" is itself a pseudonym; the boxer was born Walker Smith, Jr.[[/note]]
