7	----
8	* On ''Series/ThirtyRock'', Liz Lemon has called Jack Donaghy by his first name for most of the series, having only called him "Mr. Donaghy" or "sir" in the first few episodes. Despite this, he continues to call her "Lemon", which led to this slip-up when he tried to pass her off as his girlfriend:
9	-->'''Jack''': This is my live-in girlfriend, Lemon.\
10	'''Liz''': Elizabeth.\
11	'''Jack''': Elizabeth.
12	** Notably, Jack started out by calling Liz by her first name, just like all his other employees. Switching to using "Lemon", ironically, occurred when they became friends.
13	** Being the lowest level employee to appear regularly and exceedingly polite to boot, Kenneth calls everyone "Mr./Mrs./Miss [last name]" or "sir/ma'am". In one episode, Liz noted that he "calls Tracy's lizard 'sir'."
14	* (Erin) Silver from the sequel series ''Series/NineOhTwoOneOh'' is commonly called by her last name, Silver. Even her mother and sister call her by her last name Silver too.
15	* PlayedWith in ''Series/TheAdventuresOfSuperman''. The older ''Planet'' workers are mostly on a FirstNameBasis. ComicBook/JimmyOlsen gets called "Jim" by Superman/Clark and Lois and "Olsen" by Perry.
16	* ''Series/AgentsOfSHIELD'' has an interesting example. Most of the main characters are referred to as "Agent Last Name" or just their last name, with first names only being used during moments of emotional intensity between characters that are friends or more than friends...except Agent Fitz. ''Nobody'' calls him Leopold or even Leo. Even after Simmons became his girlfriend (later wife) and he started regularly calling her Jemma, she still refers to him as Fitz. Most likely a personal preference on his part.
17	* ''Series/{{Alias}}'' -- Since everyone's in the CIA, most of the characters in Alias go by surnames -- Sydney calls the male lead "Vaughn" even while giving birth to his daughter. This meant that his short-lived Season 3 wife earned a double take from the audience every time she called him "Michael", seeding distrust and dislike of the character well before her reveal as TheMole.
18	** {{Lampshaded}} in this exchange:
19	--->'''Sydney''': Vaughn?\
20	'''Vaughn''': How come you never call me Michael?\
21	'''Sydney''': I call you Michael sometimes.\
22	[{{beat}}]\
23	'''Sydney''': Vaughn.
24	* ''Series/{{Angel}}'':
25	** Gunn, who is only called Charles by Fred (especially while they dated), and Knox. Wesley sometimes did also.
26	** Doyle, to the extent that Angel and Cordelia are surprised to learn his name is Allen.
27	* On ''Series/AreYouBeingServed'', the staff of Grace Brothers - apart from very rare occasions - always addressed one another formally ("Mr. Lucas", "Mr. Humphries", "Miss Brahms", etc.). Among the characters, Captain Peacock and Mr. Grainger tended to use each other's given names (Stephen and Ernest, respectively) most frequently in private conversation.
28	** In the episode "The Old Order Changes", the culture of the store was (temporarily) changed to be more informal, and staff were required to address each other by first name. Mr. Lucas was not happy to have to reveal that his first name was "Dick".
29	* ''Series/{{Arrow}}'': Most characters are referred to by first names, but John Diggle is almost always "Diggle" or "Dig", unless he and Oliver are having a FriendshipMoment. Quentin Lance is usually referred to as "Detective Lance" and later, "Captain Lance". Some bad guys, like Damien Darhk, also frequently got the LastNameBasis treatment.
30	* ''Series/TheATeam'' has H.M. Murdock. His first name is never even revealed, and it's rare for someone to call him by his initials. The rest of the team always calls him Murdock.
31	* On ''Series/AufWiedersehenPet'', Moxey's is simply Moxey to everyone his first name (Albert) is only used twice in the show, and the first time wasn't until the end of the second series. Sometime between these two uses, one character claimed that Moxey was his full name, although the police call him "Albert Moxey" only an episode or two later.
32	* John Steed and Emma Peel always addressed each other as "Steed" and "Mrs. Peel" on ''Series/TheAvengers1960s''.
33	* ''Series/BarneyMiller'' is an interesting case. Stan "Wojo" Wojciehowicz, Ron Harris, and Arthur Dietrich are almost always referred to by their last names in the squadroom (though Liz Miller calls them by their first names) which is to be expected among police officers. Nick Yemana, who is technically the NumberTwo, is Nick, and Captain Barney Miller is Barney. Meanwhile, Phil Fish is called Fish by everyone, even his ''wife''.
34	* In [[Series/Batman1966 the 1966 Batman series]], Chief O'Hara's little known first name is Miles.
35	* On ''Series/{{Becker}}'', the title character (Dr. John Becker) is on a last name basis with nearly the entire cast with everyone except for his nurse, Margaret and best friend Jake.
36	* In ''The Beiderbecke Trilogy'', the main characters are most commonly referred to as Mr Chaplain and Mrs Swinburne. In the second serial, the latter is utterly surprised that the former calls her "Jill", and he admits that he only did so because "I'm shit scared." This comes after the two have been in a sexual relationship for over two years, and known each other far longer.
37	* Mitchell of ''Series/{{Being Human\|UK}}'' takes until season two to let on to the viewer that this is actually his surname (his given name is John). Justified, as being a century-old vampire he's of a generation where last name basis would have been prevalent.
38	* On ''Series/TheBigBangTheory'', Howard and Raj are often referred to by their last names (Wolowitz and Koothrappali), especially in the early seasons.
39	** Naturally, several people from the University are referred to by their titles and last name, such as President Seibert and Dr. Gablehouser. Barry Kripke is also an example, he is rarely referred to by his first name, and refers to the other characters by their last names only.
40	* ''Series/BlakesSeven'' especially in reference to Kerr Avon Is only Avon. Even his girlfriend only ever called him Avon. Creator/PaulDarrow speculated that was because "Kerr" isn't a very good first name.
41	** An interesting case because in this show because generally all the guys are referred by last name (Blake, Avon, Gan, Tarrant, Travis) and all the gals by first (Jenna, Dayna, Cally) with the rather odd exception of Vila, whose surname (Restal) is barely reference through the course of the series. Even BigBad Servalan talks to him on a first name basis. (Nobody knows whether Servalan and Soolin are first or last names though..)
42	*** It's more than likely that Vila doesn't get the last name treatment because he's lower class than the rest of the crew.
43	* In ''Series/{{Blindspot}}'', Dr. Patterson is only referred to by her last name.
44	* ''Series/{{Bones}}'' has (Seeley) Booth, (Temperance) Brennan, (Jack) Hodgins, (Daniel) Goodman, and (Lance) Sweets. When Hodgins and Angela Montenegro (who ''does'' go by her first name) are dating, even she calls him "Hodgins." Even when he ''proposes'' and now that they're married.
45	** Brennan usually refers to her interns by title and last name, though everyone else uses their given names. (It is also pointed out that her use of "Mr." or "Mrs." is a subtle reminder that the intern in question doesn't yet have a doctorate.) This also serves to indicate how much closer her intern/mentor relationship was with Zack, whom she did address by given name.
46	** Booth almost exclusively addresses Brennan as "Bones" (and is the only person allowed to do so), not "Temperance", and ''never'' "Tempe"; even in the hallucination/dream she was "Bren". There were a couple of FirstNameBasis from Booth in season one, and one in the series finale. It’s often SeriousBusiness when he calls her Temperance.
47	** Sweets is called by his first name by both of his girlfriends.
48	*** Hmm, is his name Lancelot?
49	** Sully was another one. It's short for his last name, Sullivan.
50	** Interestingly, when Booth's brother shows up, Brennan keeps calling them both Booth, although Angela amends the brother's "name" to "Booth Lite".
51	** Season 9 onward had (James) Aubrey.
52	* On ''Series/BoyMeetsWorld'', Mr. Feeny referred to all of his students by their formal title and last name ("Mr. Matthews", "Mr. Hunter", "Ms. Lawrence"), though occasionally he would use their first name instead (particularly Eric, who for much of the show's run was no longer a student of his - and presumably to avoid the problem of having two "Mr. Matthews"es). (Stuart) Minkus was the only character whom ''everyone'' addressed on a LastNameBasis Minkus, except for Topanga.
53	* ''Series/TheBradyBunch'': Alice refers to Mike and Carol as "Mr. and Mrs. Brady" throughout the entire run, even though she is virtually family.
54	* ''Series/BreakingBad'':
55	** Jesse never really gets over his high school habit of calling Walt "Mr. White". He calls his partner by his first name exactly once during the series, and it's a deliberate sign of disrespect. Oddly enough, Walt is one of the few people to consistently call him "Jesse" rather than "Pinkman".
56	** A handful of recurring characters on the show are referred to exclusively by their last names, with the most prominent examples likely being (Steven) Gomez[[note]]better-known as "Gomie" to Hank[[/note]] and (Patrick) Kuby.
57	* ''Series/BrooklynNineNine'': Played with. In general the characters stick to last names when actively working, but often use first names outside of work. They also shift away from last name basis as the series goes on and they get closer, although Captain Holt and Sgt Jeffords tend to use both titles and last names and Captain Holt is almost only called his first name by his husband. Also played straight with Hitchcock and Scully.
58	* ''Series/BuffyTheVampireSlayer'':
59	** Buffy and friends refer to Rupert Giles as just Giles. He even calls ''himself'' Giles on occasion. The only exceptions are Jenny Calendar, Joyce Summers and Spike (who call him Rupert), and Tara and Andrew (who call him Mr. Giles). And Ethan Rayne, who calls him [[RedBaron Ripper]].
60	** Oz was known solely by his nickname (a shortened form of his last name Osbourne) through his entire run on the show. His full name, Daniel Osbourne, was not revealed until after he left.
61	** In "Crush" Spike calls Buffy by her last name "Summers" while making his AnguishedDeclarationOfLove, presumably to show he's serious.
62	** As expected for adults, the three Sunnydale High principals throughout the series are primarily known by their last names. [[note]]Flutie's first name is Robert, Snyder's first initial is R, and Wood's first name is Robin.[[/note]]
63	* ''Series/{{Castle\|2009}}'' and Beckett. Initially, she only called him Rick when she was teasing him, but in Season 3, she occasionally used his first name [[YouCalledMeXItMustBeSerious in serious situations]]. He's called her Kate a handful of times, all of them dramatic: [[spoiler:once when when she was emotionally upset and he was trying to stop her leaving the station, continuously shouting it out frantically when he was trying to find her in her exploded apartment, and several times in the season three finale episode]].
64	** It's revealed in one episode that he made up his last name, as it sounds better for a writer, and had his middle name legally changed to Edgar (after Creator/EdgarAllanPoe). His real name is Richard Alexander Rodgers.
65	** [[spoiler: Despite hooking up in Season 5 and marrying in Season 7, they still call each other Castle and Beckett. Even at home. In bed.]]
66	** Alexis also refers to her [[spoiler: new stepmom]] as Beckett, although this is probably due to hearing her dad call her Beckett for several years.
67	** Detectives Ryan and Esposito are very rarely referred to by their first names (Kevin and Javier) either, though "Espo" is a common nickname for Esposito.
68	* ''Series/ChouSeiShinSeries'': In ''Genseishin Justiriser'', Yuka eventually graduates from saying "Date-kun" to the [[UsefulNotes/JapaneseHonorifics honorific]]-free "Shouta". Shouta, however, is a bit slow on the uptake, but Shinya pays attention and remarks on it.
69	* ''Series/ClassicsDarkAndDangerous'': "Recap/TheUglyLittleBoy": In a [[AdaptationNameChange change from the original story]], Dr Hoskins goes the entire time without using a first name, nor is it included in the credits.
70	* ''Series/ClassOf09'': Poet's first name is Ashley, but everyone just calls her by her last name Poet.
71	* ''Series/{{Columbo}}'': Lieutenant Columbo's first name is never spoken, though it's occasionally visible on his badge as a FreezeFrameBonus. When asked directly, he says that his first name is "[[TheyCallMeMisterTibbs Lieutenant]]".
72	* ''Series/ComeBackMrsNoah'': As is often the case in sitcoms co-written by David Croft, most of the characters only refer to each other by their last names, sometimes without "Mr." in the case of the male characters. We never learn Fanshaw or Garstang's first names (though Garstang's first initial is revealed to be E in "The Last Chance"), and Carstairs' first name (Damon) is only mentioned in a brief conversation with his wife in the episode "In Orbit".
73	* On ''Series/CriminalMinds'', all but one of the main characters are typically referred to by their last names. Prentiss, Morgan, Rossi, and Garcia have been referred to by their first names more frequently in later seasons, but last names are still the most common.
74	** In one of his first episodes, Rossi tells his teammates to call him Dave. Hotch at least seems to do this consistently. Likewise, Rossi tends to call Hotch by his first name, Aaron.
75	** While JJ is the only character not referred to by her last name, it's short for Jennifer Jareau, so they're not just using her first name, either.
76	** It should be noted that when talking with each other, Morgan and Garcia don't really use ''either'' given name, preferring intimate nicknames. One episode has an emotional moment between them where he calls her Penelope.
77	** JJ also rarely calls Reid by his last name, and is the only one who calls him "Spence".
78	** The only character to go completely by first name is Elle Greenaway, who left early in the second season.
79	** Since she's their boss, everyone also refers to Chief Strauss as "Strauss." The only one who uses her first name with any frequency is Rossi, [[FirstNameBasis who refers to him by his first name as well]]. She also calls Hotch by his first name Aaron.
80	* ''Series/{{CSI}}''
81	** It has Grissom, Brass, Hodges, and Ecklie, and [=McKeen=] for a while. They just used [=McKeen=] even while he was running after killing Warrick. Interesting that except for Grissom, all the other [=CSIs=] are on a first name basis.
82	** Grissom is later TheGhost, but a returned Sara continues to refer to him only as "Grissom" despite the fact that [[spoiler: ''they are now married'']]. Even after they became intimate, she only rarely called him by his first name, and only ever in private.
83	** Julie Finlay is a variation of this. Her full last name is Finlay, but she prefers to be called 'Finn'. D.B. still uses Julie sometimes, and she'll call him on it. But he's the only one she knows who does it.
84	** Occasionally, D.B. gets called Russell, but not all the time.
85	* ''Series/CSIMiami'': With two exceptions, all the main characters are on a first name basis; Tim Speedle usually goes by a shortened version of his last name, "Speed", and Horatio always calls Ryan "Mr. Wolfe". (Horatio himself is referred to as "H" most of the time.)
86	* ''Series/{{CSI NY}}'' has (Don) Flack and (Sheldon) Hawkes, although their first names get used sometimes as well, most often by Mac. Sometimes when a character answers the phone, they refer to themselves by last name. Mac and Stella do it a lot..."Bonasera" and "Taylor." The superiors get it sometimes. Gerard comes to mind. Mac is an aversion of sorts, a rare example where it isn't a shortened last name, but a nickname for his first name ([=McCanna=], which is ''never'' spoken during the entire series run).
87	* On ''Series/DawsonsCreek'', Pacey usually calls his girlfriends by their last names. Namely (Andie) [=McPhee=] and (Joey) Potter.
88	* ''Series/{{Deputy}}'': After coming out as nonbinary, Bishop decides to use only their last name along with using they/them pronouns, dropping their first name Brianna. Even prior to this they were mostly called just Bishop by colleagues.
89	* ''Series/{{Dexter}}'': Almost all the characters in Miami Metro unless they're particularly close to each other (Angel Batista and Maria [=LaGuerta=] during their marriage, siblings Dexter and Debra Morgan, etc.). This sometimes leads to confusion when a character calls out for "Morgan" when Dex and Deb are both present. Subverted to great effect by [[spoiler:Doakes to Dexter in episode 2.11 to reflect that in addition to capturing a killer, he now also wants to help Dexter by turning him in]].
90	* In ''Series/DharmaAndGreg'', Greg's father Edward always referred to Dharma's father Larry as "Finkelstein".
91	* In ''Series/{{Diablero}}'', Ventura is usually called either by his surname or his title, Father (padre in Spanish, or the slightly-condescending diminutive form padrecito). Hardly anyone ever calls him "Ramiro."
92	* ''Series/DoctorWho'':
93	** The First Doctor always called one of his first companions Ian by his second name, "Chesterton" (and frequently got it wrong).
94	** In the UNIT era, Captain Yates was occasionally referred to as "Mike", Brigadier Lethbridge-Stewart was even more occasionally "Alistair" (but more often simply ''the'' Brigadier), but RSM Benton didn't even get the name "John" confirmed on-screen until it was used in a semi-official fanvid. In the Twelfth Doctor short story "Lights Out", the Doctor struggles to remember Benton's first name, before recalling it was "Sergeant".
95	** Inverted in [[Recap/DoctorWhoS15E1HorrorOfFangRock "Horror of Fang Rock"]]: Skinsale and the other toffs keep the working-class Vince at arm's length, always calling him "Harker"; the Doctor makes a point of addressing him as "Vince."
96	** The Fifth Doctor's companion Vislor Turlough was always referred to as Turlough. (He was introduced at a boys' prep school, where it came across as extremely normal, but the practice was kept up afterwards; his first name was not even revealed until his last story, and was used only the once.)
97	** Mr. Saxon in Series 3. Despite his numerous mentions throughout the season, and the fact that he had been running for Prime Minister since before that series even began, his first name is barely mentioned until the finale, by which time it's become pretty much irrelevant.
98	--->'''[[Recap/DoctorWhoS30E17E18TheEndOfTime Lucy Saxon]]:''' [[DyingMomentOfAwesome 'Till death do us part,]] ''[[DyingMomentOfAwesome Harry!]]''
99	** [[Recap/DoctorWhoS29E742 "42"]]: Of the seven crewmembers of the ''Pentallian'', only Riley, Abi and Erina are addressed by their first names, with those of Captain [=McDonnell=], Korwin, Ashton and Scannell being available solely in the credits.
100	** The Eleventh Doctor ''sometimes'' calls Amy Pond by her first name, but just as often calls her "Pond", as in "Come along, Pond[[AlternateUniverse (s)]]!" Possibly this is because he preferred "Amelia" and by the sixth season "Amelia" had evolved into YouCalledMeXItMustBeSerious territory.
101	** UNIT scientist Osgood prefers to go by her surname because her first name is the incredibly [[EmbarrassingFirstName embarrassing]] "Petronella".
102	* Everyone in ''Series/DrQuinnMedicineWoman'' called Sully solely by his surname. This was probably partly because he [[EmbarrassingFirstName was embarrassed by his name, Byron]].
103	* ''Series/DueSouth'' Fraser-rarely did anyone ever call him Benton. Thatcher and Welsh as well, but it was usually a formality, 'Inspector Thatcher' and 'Lt. Welsh'.
104	* Throughout 15 seasons of ''Series/{{ER}}'', you could probably count on one hand the number of times John Carter was called by his first name, with the only ones to consistently call him "John" being his parents, grandparents and wife.
105	* ''Series/{{Eureka}}'':
106	** Douglas Fargo is almost universally referred to as "Fargo". The only people who ever call him any derivative of "Douglas" are [[{{Crossover}} Claudia]] from ''{{Series/Warehouse 13}}'' (who does it in response to his claim that "everybody calls me Fargo") and himself (one of his passwords is "[[Series/BuffyTheVampireSlayer Dougie the Vampire Slayer]]").
107	*** His new girlfriend (played by Creator/FeliciaDay) refers to him as "Douglas" as well.
108	** Allison used to refer to Carter by his last name. Then they became close friends and, eventually, lovers. Naturally, she switched to "Jack".
109	* ''Series/FallingSkies'' has John Pope, whom everyone refers to as simply "Pope". Pope himself refers to Tom Mason by his last name, at least when he's in a (relatively) friendly mood.
110	* On ''Series/{{Farscape}}'', everyone calls John Crichton just plain "Crichton." Even his girlfriend, except for a few very serious situations. The only people who regularly call him "John" are [[BigBad Scorpius]] and [[EvilSorcerer Maldis]].
111	* Wash, basically, on ''{{Series/Firefly}}''. Even his wife calls him Wash. it’s short for Washburne, and it could be he’s just not fond of his actual first name “Hoban”. He says something to that effect in one of the comics.
112	* ''Series/ForeverKnight'' (Don) Schanke. And by the same token, Schanke would sometimes just call Nick 'Knight'. The captains got it a lot too when they were referred to...even when the formal 'Captain' wasn't used, as in talking to them, it was often 'Stonetree' 'Cohen' 'Reese'. Lacroix was another last name guy. No one ever called him Lucian. Tracy usually only got the formal Detective Vetter version on the job sometimes, but never from Nick.
113	* ''Series/{{Fringe}}'': Peter refers to Olivia Dunham as 'Olivia' at the beginning of the show, and then changes to calling her 'Dunham' for no discernable reason.
114	* (Damian) Spinelli and (Jasper) "Jax" Jacks and (Hamilton) Finn from ''Series/GeneralHospital'' (though the latter is usually spelled out "Jax").
115	* ''Series/GhostHunters''' Dave Tango is often referred to as "Tango".
116	* Handled interestingly on ''Series/GilligansIsland''. The Howells are always referred to by the other regular characters as "Mr. Howell" and "Mrs. Howell", but are on a first-name basis with each other (though "Lovey" is a pet name, not her actual given name, which is Eunice). Ginger Grant is mostly called "Ginger", but is sometimes called "Miss Grant", especially by Mr. Howell. Mary Ann, though, is almost always just called "Mary Ann" to the extent that many fans wouldn't know the character's last name (it's Summers). The Professor and the Skipper have names, but even fewer fans know them, as they're always just referred to by their titles (their names are Roy Hinkley and Jonas Grumby, respectively). Gilligan himself is the really odd case, as he is never called any name other than Gilligan. It isn't even established whether it's his given name or his surname.
117	** According to creator Sherwood Schwartz's original treatment for the show, Gilligan was the character's last name, with his first name being Willy. However, this name was never mentioned in any episode or movie, and whether it should be considered canon or not is greatly debated.
118	* This was originally the plan with Farkle on ''Series/GirlMeetsWorld'' (his first name would've been Sheamus), until the producers decided to make him the son of ''Series/BoyMeetsWorld'' egghead Stuart Minkus or Simply just Minkus to everyone he even to referred Himself as Minkus (who himself ''was'' an example of this trope on ''BMW'').
119	** And speaking of ''Boy Meets World'', Mr. Feeny is both a recipient and a giver of this trope. Everyone but Cory's parents call him "Mr. Feeny" (or in Eric's case, "FEE-HEE-HEE-HEENAY!"), and he calls all of his students by their last name.
120	* ''Series/{{Glee}}'': Noah Puckerman is usually called "Puck" and David Karofsky is frequently "Karofsky."
121	* In the episode "The Shershow Redemption" of ''Series/HappyEndings'', [[ButtMonkey Shershow]] is only called by his last name Shershow, and it is even used as a short hand for 'loser'. Though he ditches it and becomes Jason as he now has his life together.
122	-->'''Melinda:''' Anyway you guys, Jason's told me so much about you.\
123	'''Max:''' Who's Jason?\
124	'''Dave:''' That's Shershow's first name, that's so Shershow that you don't know that.
125	* A few characters on ''{{Series/Heroes}}'' tend to call each other by their last names for formality/unfamiliarity reasons. Noah Bennet particularly is often just called "Bennet", which meant his first name was unknown for a long time. Mohinder is frequently just called "Suresh" a lot, even by Matt, ''his roommate''. One scene has Peter walking into Mohinder's unlocked apartment and finding him seemingly missing, and calling out, "Suresh? Suresh?" and then, exasperated, "Mohinder?!"
126	* On ''{{Series/Highlander}}'', Tessa was the only one to ever call Duncan by his first name. Everyone else either called him Macleod or the shortened form, Mac. Even Tessa used it some of the time.
127	* ''Series/{{Homeland}}''. Sergeant Nicholas Brody is just simply "Brody" by everyone, including his wife.
128	* The rule of thumb for main characters on ''Series/HomicideLifeOnTheStreet'':
129	** Despite their differences, Pembleton and Bayliss become HeterosexualLifePartners, but only occasionally call each other "Frank" or "Tim". Of the two of them, Bayliss does it a little more.
130	** [[DaChief Al Giardello]] is universally referred to as "Gee", which sounds like a shortening of his surname, although it isn't.[[note]]In the final episode her reveals that it's the only thing he could say on his first murder scene.[[/note]]
131	** John Munch is usually just Munch, although Howard uses the affectionate nickname "Munchy".
132	** For Howard herself this trope results in GenderBlenderName.
133	** Meldrick Lewis is the glaring exception, but his last name could easily be a given name and his first name sounds like some kind of Germanic surname.
134	* On ''Series/TheHoneymooners'' Ralph and his other friends call Ed Norton "Norton" all to everyone even his wife calls him Ed or Norton mostly Norton.
135	* ''Series/{{House}}'' features House, Wilson, Cuddy, Cameron, Foreman, Chase, Taub, and Kutner. Cameron and Chase are in a long-term relationship, but are on a LastNameBasis. Only Amber Volakis is regularly called by her first name.
136	** This can actually get confusing, since Chase, Cameron, and Wilson are all reasonable first names. It can be very easy to forget that their first names are actually Robert, Allison, and James, respectively. Even when you know it's their last names, it's incredibly easy to catch yourself thinking it's their first name.
137	** Even Amber was originally called [[OnlyKnownByTheirNickname Cutthroat Bitch]].
138	** Thirteen's full name was eventually revealed: Dr. Remy Hadley.
139	** This was joked with in a Season One episode, where Cameron begins to call her colleagues by their first names after having read an "empowerment at the work place" book. This only confuses Chase and Foreman, who respond by saying her name with emphasis when they answer her questions.
140	--->'''Cameron:''' Are you mocking me?\
141	'''Foreman:''' Duh... ''Allison''.
142	** House's team are so used to calling each other by their last names that when they found a book Wilson had given House with the inscription "''Greg, made me think of you.''", they immediately came to the conclusion that it must have been given by a woman. Of course, some fans may think this indicates [[HoYay other things...]]
143	** In one episode of the now most recent season, the writers even [[LampshadeHanging lampshade]] this with the characters discussing (Eric) Foreman's and Thirteen's continued habit of calling each other by their work names.
144	** This trope was also invoked to indicate House and [[NewOldFlame Stacy]]'s relationship; besides his mother, she's the only person on the series who regularly calls him Greg.
145	** Once they got together Chase and Cameron called each other by their first names in private.
146	** Wilson and Cameron have also been known to call each other by their first names from the first season.
147	** Lampshaded by [[spoiler:Cuddy's mother]] in Season 7, when she asks Cuddy [[spoiler:"why do you call him "House"? The man's name is Greg."]]
148	** When Wilson began dating Amber (the only first-namer on the show) she still referred to him as Wilson, possibly because the writers were so used to the name they just didn't think about it, and possibly because they thought the viewers might not know who "James" was.
149	* ''Series/HRPufnstuf'' has (Willimina W.) Witchiepoo.
150	* ''Series/{{iCarly}}'' has a variant with Gibby, whose full name is "Orenthal Gibson". Also, Sam and Freddie will sometimes refer to each other by their respective last names of "Puckett" and "Benson".
151	* Pretty much all the adults in ''Series/TheInbetweeners'' are referred to as Mr / Mrs X (or "X's mum / dad") in-show, their first names only appearing in the credits. Mr. Gilbert's first name is mentioned a couple of times (it's Phil) but [[BerserkButton he doesn't take kindly to being called by it]].
152	* On ''Series/TheInspectorLynleyMysteries'', the titular Inspector Lynley calls his partner Sergeant Havers one of two things: "Sergeant" or "Havers." He does call her "[[FirstNameBasis Barbara]]" when she visits his family in Cornwall, but when they get tangled up in a mystery - [[BusmansHoliday as they inevitably do]] - and they're back on duty, well, to quote Barbara, "It's bye-bye 'Barbara' and hello 'Havers'!" He also calls her Barbara [[YouCalledMeXItMustBeSerious during particularly intense or emotional moments]], beginning in their second episode together ("Well Schooled in Murder") when her father dies and continuing in this vein through the next several series. By the sixth series, however, after [[spoiler:he leaned on her after his wife's death]], [[FirstNameBasis he calls her 'Barbara' almost exclusively]], reverting to 'Havers' only when he is cross with her; this signals a fundamental shift in their relationship. In contrast to her partner, Barbara never calls him ''anything'' other than 'sir', as he's her superior officer (and a Lord to boot, while she is working-class). Still, the ''way'' she says it evolves, from stiffly formal to fond and often teasing.
153	* Famously, ''Series/InspectorMorse'''s [[EmbarrassingFirstName full name]] [[spoiler:Endeavour]] wasn't revealed until 1997.
154	** Morse almost exclusively refers to his sergeant as "Lewis." The number of times Morse refers to Lewis as "Robbie" can be counted on one hand.
155	** Averted by the pathologist in seasons 1 and 2, who is always "[[FirstNameBasis Max]]" to the extent his last name was completely unknown until he showed up as a character on the prequel series ''Series/{{Endeavour}}''. Played straight with Dr. ([[EmbarrassingFirstName Grayling]]) Russell and Dr. (Laura) Hobson. Lewis and Hobson do start calling each other "Robbie" and "Laura" after their RelationshipUpgrade, though.
156	** Both Lewis and Morse nearly always refer to other cops and suspects by their surnames (Morse is exclusively "Sir" for Lewis). Superiors (like Chief Superintendent Strange, whose first name "James" is only revealed in ''Series/{{Endeavour}}'') are usually referred to by rank or as "Sir" in their presence, although even they generally get the surname treatment when Lewis or Morse is talking about them in third person.
157	* ''Series/TheITCrowd'' gives us Maurice Moss, who is typically referred to by his last name.
158	* ''Series/ItsAwfullyBadForYourEyesDarling'': Hugo from "A New Lease" calls Clover "Miss Mason" out of respect as she is a possible customer.
159	* ''Series/{{JAG}}'' had an interesting variant with Major (from season 5: Lieutenant Colonel) Sarah Mackenzie. Everyone of equal or higher rank in the office called her "Mac", and very rarely did anyone use her first name Sarah. Everyone below her in rank called her rank & last name, only rank or "Ma'am", even when they were off-duty. This is standard military protocol and courtesy.
160	* Friedman in ''Series/JoanOfArcadia''. His first name is never revealed.
161	* While everyone else among ''Series/KamenRiderBuild'' protagonists is referred to by their first name, Ryuga Banjo for some reason is called Banjo instead.
162	* ''Series/LAsFinest'': Syd usually calls Nancy by her last name, [=McKenna=].
163	* On ''Series/LawAndOrderCriminalIntent'', the two original partners typically only referred to each other as "Goren" and "Eames." When Eames occasionally referred to Goren as "Bobby," it was universally an example of YouCalledMeXItMustBeSerious.
164	** The only person who consistently referred to him as "Bobby" was a recurring villain, who kept trying to prove a NotSoDifferentRemark.
165	* The FiveManBand on ''Series/LawAndOrderSpecialVictimsUnit'' are Cragen, Benson and Stabler, Munch, Fin, and Lake. Only Fin is usually referred to by his first name, and that's just because it's easier to pronounce than Tutuola; Fin is in fact a nickname for his given name, "Odafin".
166	** Although there are other layers to this one, as in real life. Benson and Stabler call each other "Liv" and "El", which, being PlatonicLifePartners, makes sense. Alexandra Cabot was always called Alex by everyone, and it was noted (by their [[LesYay shippers]], unsurprisingly) that she was one of the few people who called Benson "Olivia", and, on occasion, "Liv". Similarly, everyone called Casey Novak "Casey", while they called her ReplacementScrappy "Greylek". Occasionally someone else calls Benson "Liv" - you can then be sure that [[YouCalledMeXItMustBeSerious the shit is about to hit the fan]].
167	*** Alex Cabot was unique in that she referred to ''everyone'' by their first name - including Huang and even Cragen. Olivia isn't that special after all.
168	** Averted by Cragen, who always refers to his detectives and [=ADA=]s by their first name (except for the aforementioned Greylek), befitting his role as TeamDad. He's the only character to refer to Munch as "John". Played very straight in reverse, however - nobody ''ever'' refers to Cragen as "Donald" or "Don", and address him by his title instead (again typical for a parental figure).
169	** Dr. Huang is almost never referred to as "George", not even by Cragen or Benson, perhaps in deference to his role as TheShrink. On the other hand, Dr. Warner usually refers to Benson and Stabler as "Olivia" and "Elliot", and in turn, they always address her as "Melinda" (though when people are talking ''about'' her, she's always "Warner").
170	** ADA Rafael Barba, despite being very well-liked by the SVU squad, is called either "Counselor" or "Barba" by virtually everyone. Only one squad member, Olivia Benson, has ever called him "Rafael", and she only started doing that regularly in season 19, five years after his initial debut. In turn, he usually calls (Sonny) Carisi and (Amanda) Rollins by their last names, uses 'Fin' for Odafin Tutuola, and addresses Olivia either by her first name or, as their friendship develops, "Liv".
171	** There's somewhat of a RunningGag in the series about Carisi being on a LastNameBasis with everyone against his will, as he introduces himself by [[FriendlyAddressPrivileges inviting people]] to call him by his first name. A request that is routinely ignored. [[LampshadeHanging Lampshaded]] by Rollins when Carisi introduces himself to Cragen.
172	--->'''Carisi:''' Dominick Carisi. Call me Sonny.
173	--->'''Rollins:''' Why? No one else has.
174	** Pretty much everyone call Amanda Rollins by her last name. Though her colleagues tend to switch to "Amanda" when they show concern for her. After she and Carisi have a RelationshipUpgrade they seem to use the last name basis as a way to separate professional interactions from their personal life. So they call each other "Amanda" and "Sonny" in more private moments and "Rollins" and "Carisi" at work.
175	* ''Series/LegendsOfTomorrow'':
176	** [[TokenEvilTeammate Leonard Snart and Mick Rory]] are usually called by their last names, though the other Legends occasionally call the latter "Mick" once they begin bonding with him.
177	** Jefferson Jackson's nickname is "Jax", which is how most people call him. The only one who calls him "Jefferson" on a regular basis is his partner/father figure, Martin Stein.
178	* It isn't clear whether or [[FirstNameBasis not]] this applies to ''Series/{{Leverage}}'''s [[OnlyOneName Parker]]. Also, Alec Hardison and Jim Sterling are almost never referred to by their first names just simply their surname Hardison an Sterling.
179	** Invertefd with Elliot Spencer. His last name is barely mentioned.
180	* In ''Series/{{Lewis}}'' the titular character and Sergeant Hathaway share a similar dynamic, although Lewis uses "James" for his sergeant substantially more frequently than Morse did for him. The Chief Super is almost always called "Innocent". However, Lewis graduates to referring to Dr. Hobson as "Laura", foreshadowing their RelationshipUpgrade later in the series.
181	* ''Series/{{Lidsville}}'' has (Horatio J.) Hoodoo.
182	* ''Series/LockwoodAndCo2023'': Everyone calls Anthony Lockwood by his last name, except for his rival Kipps who calls him Tony.
183	* ''Series/{{Lost}}'' has Locke, whom only Ben and Jack call John (in Jack's case, as a sign of disrespect.) The Others routinely refer to the Losties by their last names, but use first names internally. The Losties use first names. The freighties (apart from Naomi, Charlotte and Miles) mostly use last names.
184	** It seems like a sign of disrespect when Ben calls Locke "John" too.
185	** Rousseau is also frequently addressed by her last name, and only occasionally as "Danielle," usually by Sayid.
186	** Sawyer is seldom referred to as James. The only one who tends to call him that is Juliet, and later Locke. Of course, Sawyer is not his real name.
187	** In season five, Sawyer [[spoiler:takes up the name Jim [=LeFleur=]. He is generally referred to, even by some of the Oceanic survivors, by that]].
188	** As of season 6, both Sawyer and Hurley are commonly referred to as James and Hugo, respectively. [[spoiler:Neither even have their respective nicknames in the flashsideways timeline]].
189	** A plot relevant case: [[spoiler:Jacob]] wrote his candidates down on a last name basis, causing confusion among viewers and characters in regards to candidate "[[spoiler:Kwon]]", which could refer to several characters. When he actually encounters his remaining candidates, however, he refers to each by their first names.
190	* ''Series/{{Lucifer\|2016}}'':
191	** Lucifer notably calls Ella "Ms. Lopez", despite their close relationship. This seems to stem from his respect to her profession, as he calls most people in the LAPD precinct by their last names, except for Chloe (who is consistently called "Detective", initially to tease her before becoming a genuinely AffectionateNickname) and Dan ("[[EmbarrassingNickname Detective Douche]]", then "Daniel" after they become FireForgedFriends).
192	** Ella and Maze mostly call Chloe "Decker", although they have occasionally used her first name, as well.
193	* ''Series/TheLWord: Generation Q'': Sarah Finley is almost always called just "Finley".
194	* On ''Series/{{MacGyver\|1985}}'', [=MacGyver=] is only called by his last name [=MacGyver=] and refuses to tell anyone what his [[EmbarrassingFirstName first name]] is. There are instances of even official paperwork only containing his last name [=MacGyver=]. His first name, Angus, is finally revealed in a dream sequence during the last (seventh) season of the show. His friends usually call him Mac.
195	** Not exactly the same in his case, since he just hates his first name and doesn't tell people what it is. It doesn't really indicate distance.
196	* ''Series/MagnumPI'' has the title character, (Thomas) Magnum.
197	* In ''Series/TheMentalist'', it's generally seen as jerky or disrespectful for anyone to call anyone in the workplace by first name. Van Pelt, however, is commonly called 'Grace' because she's a rookie (or used to be), Bosco and Lisbon are intimate enough to do this, Van Pelt and Rigsby of course call each other by first names even after they break up the first time, [[DaChief for some bizarre reason]], Jane always calls Minelli 'Virgil', and [[YouCalledMeXItMustBeSerious we know that things are getting bad]] when Jane calls Lisbon "Teresa". Or that he's pulling another BunnyEarsLawyer UndercoverAsLovers gambit, which, this being [[TheChessmaster Patrick Jane]], is far more likely.
198	** He does once tell her she can call him Patrick, but since he's [[LemonWackyHello under the influence of Belladonna]] she doesn't take him up on it.
199	* In one episode of ''Series/TheMuppetShow'', Kermit is particularly angry with Bunsen over his teleporter malfunctioning and causing chaos on the show. While [[ItMakesSenseInContext trying to fight off a gorilla]], he can be heard screaming "This has gotta stop! HONEYDEW!".
200	* ''Series/TheNanny'': Maxwell Sheffield, being British, refers to Fran as "Miss Fine" even as they start dating.
201	** He called her "Miss Fine" once or twice even after ''they were married.''
202	* The 2002 Miniseries ''Napoléon'' provided an unusual example of this. Napoleon and his friend General Joachim Murat routinely call each other by their surnames. Even after Napoleon is crowned Emperor, he has to make a point of telling Murat to address him as "Sire" rather than "Bonaparte".
203	* In ''Series/{{NCIS}}'', the recurring CGIS[[note]]Coast Guard Investigative Service[[/note]] Agent Abigail Borin has this with Gibbs' team to avoid breaking the OneSteveLimit with Abby Sciuto. Case in point, in her first appearance, Agent Borin and Abby Sciuto introduced themselves as "Abby" to the other simultaneously.
204	* In ''Series/{{Neighbours}}'', Mark Brennan was subject to this for a while, including to two of his love interests, Kate and Paige. The show seemed to drop this after the rest of the Brennan family were introduced, the turning point being a scene where Mark, Tyler, Aaron and Russell all respond to the name Brennan at once, and Paige realises she'll have to get in the habit of calling him Mark.
205	* ''Series/NewGirl'' has Schmidt, who is only ever referred to by his last name Schmidt. His first name being unknown was a long RunningGag and only revealed in the show's final season. Even after they get married, Cece still calls him by his last name.
206	** When one of his cousins (who ALSO exclusively goes by this surname Schmidt) visits, they argue over which one gets to be called "Schmidt". They eventually settle on calling his cousin "Big Schmidt".
207	* ''Series/{{Nikita}}'': While most of the other main characters are on a strictly first-name basis, Birkhoff is referred to almost exclusively by his last name. Only Sonya calls him Seymour.
208	* On ''Series/TheOC'', Summer persists in calling Seth by his last name, Cohen, even after they're in a relationship.
209	* ''Series/OnceUponATime'': Rumplestiltskin's human Storybrooke counterpart Mr. Gold is regularly referred to just as 'Gold,' particularly later in the first season and especially by Regina (The Evil Queen). Though he might not even ''have'' a first name, since Mr. Gold [[FakeMemories isn't who he actually is anyway]].
210	* ''Series/OneOfUsIsLying'': Nate calls Bronwyn by her last name Rojas.
211	* In ''Series/OneLifeToLive'', Robert Ford is known as Bobby to his family and Jessica but is otherwise referred to solely as Ford. There is also (Oliver) Fish.
212	* ''Series/OpenAllHours'' has (Albert E.) Arkwright, only ever referred to as Arkwright, including by his love interest and his nephew.
213	* ''Series/OurMissBrooks'': Brooks, Boynton, and Conklin always address each other formally, even outside of school.
214	* ''Series/TheOuterLimits1995'': In "[[Recap/TheOuterLimits1995S4E17Lithia Lithia]]" Major Mercer doesn't tell the women what his first name is. It's part of the episode's twist ending as Hera knows its Jason, calling Mercer by this, since she actually had been engaged to him. Before, everyone just called him Mercer, with or without Major.
215	* ''{{Series/Pandora}}'': Delaney Pilar is usually called "Pilar" at her request.
216	* ''Series/PeepShow'': Alan Johnson is almost always referred to as simply "Johnson".
217	* ''Series/PersonOfInterest''
218	** Harold Finch regularly addresses people formally, and usually only calls Reese "John" [[YouCalledMeXItMustBeSerious when he's worried about him and/or Reese is in more danger than usual]] (although since Reese and Finch aren't their real last names (which have not been revealed), it's more like Assumed Last Name Basis). This includes referring to Root as "Ms. Groves" even though she always calls him "Harold"--in her case it's because she started off as a villain and it takes a long time for Finch to accept her as a FireForgedFriend.
219	** Sameen Shaw is generally referred to by her last name Shaw, likely because of her stand-off relationship with the rest of Team Machine.
220	** Detective Joss Carter likewise went by this to the point that when she was asked for her first name by Fusco, she said it was Detective. It annoys Fusco to find out she's on a FirstNameBasis with Reese.
221	** The episode "Booked Solid" does this as an EstablishingCharacterMoment. Finch is going undercover by getting a job at a hotel. The hotel manager curtly insists on this trope because Finch is now his employee, despite having encouraged Finch to use his first name during his interview.
222	* ''Series/PrettyGuardianSailorMoon'' has Ami starting out calling Usagi by her surname. An entire episode is devoted to getting her to use "Usagi-chan" and "Rei-chan", and we later find out that her mother, a doctor, is only able to communicate with Ami via messages on a whiteboard.
223	* ''Series/{{Primeval}}'': Very few people call Nick Cutter, James Lester, and Capt. Tom Ryan by their first names, and Capt. Becker's name isn't even ''mentioned'' in the series. WordOfGod says it's Hilary. No wonder he never mentioned it.
224	* ''Series/PrisonBreak'': Varies depending on the character and their relationship. For example, Mahone calls Michael Scofield in season two when he's chasing him, varies it in season three (when they're uneasy allies), and Michael in season four when they become friendly.
225	* In ''Series/TheProfessionals'', Ray Doyle is either called Ray or Doyle, but William Bodie is always Bodie, never William.
226	* In ''Series/{{Psych}}'' everybody calls Burton Guster "Gus." Also Lassiter is on a last name basis with everyone.
227	** Shawn never refers to Lassiter anything other than "Lassie". Lassiter, while initially annoyed, eventually accepted it as an inevitability, or is just ignoring it, hoping the annoying creature claiming to be psychic will go away.
228	** Gus's uncle Burton (for whom he was named) resents Gus prefering his nickname to his first name.
229	* ''Series/QuincyME'' goes even farther by never giving the titular character a first name beyond an initial. Jack Klugman always answers that Quincy's first name was, in fact, "Doctor". Even his ''girlfriends''[[spoiler: and wife in the final few episodes]] called him Quincy.
230	* Rimmer and Lister in ''Series/RedDwarf''. Taken to the point that when they're being affectionate (whether mockingly or genuinely so) it's not Arnie and Dave, but Rimsie and Listy.
231	** The only time that they do refer to the other as 'David' and 'Arnold', is in the third season episode "Polymorph". But then, YMMV as they aren't really themselves, because the titular Polymorph had stolen an emotion from each(fear from Lister and anger from Rimmer).
232	** Rimmer has such a cold relationship with his mother that she addresses him in letters as 'Dear Rimmer'.
233	** In "Kryten", Rimmer asks Lister not to call him "Rimmer" in front of the girls ("You always emphasise the 'Rim', it makes me sound like a lavatory disinfectant"), and a genuinely baffled Lister says "Well, what ''should'' I call you?"
234	** While earlier episodes had Holly refer to them as 'David' and 'Arnold', they're 'Lister' and 'Rimmer' by the fourth season.
235	*** Similarly, earlier episodes had Kryten use 'Mr David' and 'Mr Arnold', before switching to 'Mr Lister' and 'Mr Rimmer'.
236	** Played with for Kochanski, who varies between nicknames and surname with Lister (her ex-boyfriend) depending on context, but exclusively uses surnames with anyone else.
237	* ''Series/RizzoliAndIsles'': Played straight with (Vince) Korsak and (Barry) Frost. Mostly played straight with Maura Isles, who most people refer to as Dr. Isles, except Jane who calls her Maura. Mostly averted with Jane and Frankie, probably because they are siblings who work together, and a "Detective Rizzoli" and an "Officer Rizzoli" in the same place [[OneSteveLimit would get confusing]].
238	* ''Series/RootIntoEurope'': Henry Root, practically BritishStuffiness incarnate, addresses his wife Muriel as "Mrs. Root". Muriel is at least relaxed enough to call him Henry.
239	* ''Series/{{Roswell}}'' Sheriff Valenti, often even after he wasn't sheriff anymore, he was still Valenti. (Mostly because he was an adult character in a cast largely composed of teenagers; Maria's mother, his sometime-love interest, called him "Jim".)
240	* ''Series/{{Scrubs}}'':
241	** No one calls Christopher Turk by his first name. Even his wife Carla and his {{Heterosexual Life Partner\|s}} J.D. refer to him only as "Turk". Presumably because of this, Dr. Kelso thought that "Turk" was actually his first name, and he somehow got the idea that his last name was "Turkleton".
242	--->'''Kelso:''' ''[very drunk]'' Ah! Dr. Turkleton!\
243	'''Turk:''' Actually, sir, it's "Turk".\
244	'''Kelso:''' That's your ''first'' name.\
245	'''Turk:''' You think my name is ''Turk Turkleton''?\
246	''[Carla walks up]''\
247	'''Kelso:''' And ''Mrs.'' Turkleton! '''The Turkletons!'''
248	** He does eventually learn Turk's actual name... but decides he likes "Turkleton" better and so continues to call him that.
249	** Carla does call Turk by his first name when she's mad or when they're having sex.
250	--->'''Turk:''' Christopher? You only call me "Christopher" when you're mad or when we're having sex. Baby, are you mad when we're having sex?\
251	'''Carla:''' Sometimes.
252	** Turk's brother calls him "Chrissy". JD's brother does call him "Christopher". One episode has Turk's father call and J.D. calling him by Christopher when he says he's not home at the time.
253	* Kramer from ''Series/{{Seinfeld}}''. Is known primarily by his surname Kramer Even after his first name Cosmo was revealed, people still kept using his last name Kramer. (Not that people weren't enamored by his first name Cosmo when it was revealed.) Also true for Newman.
254	* ''Series/SevenDays'': With the main exceptions of Craig Donovan toward Frank Parker (but not in return) and most people toward Olga Vukavitch, characters refer to each other by last name (although Olga addresses people by title as well.)
255	* ''Series/SexAndTheCity'': Carrie was usually on a first name basis with her boyfriends through the years (with the exception of NoNameGiven Mr. Big) but for some reason referred to Jack Berger by his last name only.
256	* ''Series/{{Sherlock}}''
257	** Averts this trope (unlike every other version of Sherlock Holmes), by [[FirstNameBasis having the leads call each other "Sherlock" and "John" exclusively]]--except for Lestrade. Sherlock doesn't even know what his first name is until part way through the second series, and it's implied the two have know each other for years.
258	--->'''Sherlock:''' Is that why you're here? You're incognito? Undercover with that ridiculous alias, ''"Greg!"''\
259	''[beat]''\
260	'''John:''' That's his ''name''.\
261	'''Sherlock:''' ...is it?\
262	'''Lestrade:''' Yes! If you'd ever bothered to find out!
263	** Mrs. Hudson is also always referred to simply as "Mrs. Hudson". One commenter described the look on Sherlock's face during the exchange with Lestrade as "The moment Sherlock began to consider that Mrs. Hudson's first name might not be 'Mrs.'"
264	* ''Series/TheShield'' also plays with this trope. Curtis Lemansky is usually referred to as "Lemonhead" or simply "Lem".
265	* The men in ''Series/SirArthurConanDoylesTheLostWorld'' are typically referred to by their last names. Typically, only Marguerite will refer to them with their first names.
266	* (Bertram) Gilfoyle in ''Series/{{Silicon Valley}}''. His first name is used very rarely.
267	* In ''Series/{{Skins}}'', James Cook's or simply just Cook just about everyone calls him Cook his first name James is used so rarely that it wouldn't be surprising if most of the main characters don't even know its James.
268	* ''Series/SleepyHollow'': Abbie primarily refers to Ichabod as "Crane"; Ichabod calls Abbie "Lieutenant" or "Miss Mills".
269	* ''Franchise/{{Stargate\|Verse}}'':
270	** On ''Series/StargateSG1'', Colonel Jack O'Neill calls his civilian scientist "Daniel" but his military officer second "Carter". Daniel Jackson, on the other hand, addresses both his military comrades by their first names, which continued even after O'Neill was promoted to Brigadier General and put in charge of the SGC. Samantha Carter calls him "Daniel" and O'Neill "Colonel/General" or "sir". Teal'c is addressed by [[OnlyOneName his only name]], and calls Jack "O'Neill" and Daniel by his [[FullNameBasis full name]], "Daniel Jackson".
271	*** This is not out of the ordinary for a military situation at all, at least for Samantha Carter's situation. Daniel is a civilian (no military rank) and a close friend and thus can be referred to even on missions as Daniel (rather than Dr. Jackson, as she does in the first episode), while O'Neill is her commanding officer. It would be inappropriate for her to refer to him by his first name while on duty, and 95% of the show is the team 'on duty'. Hence the Colonel/General and sir, even though they are [[UnresolvedSexualTension obviously close]] friends. It's worth noting that in a guest appearance on ''Series/StargateUniverse,'' O'Neill did address Carter as "Sam." Many members of the fandom are of the opinion that "sir" and "Carter" have evolved into the characters' pet names for one another.
272	*** Daniel also called Sam "Captain Carter" in the first few episodes.
273	*** And when Mitchell came along, he addressed Daniel as "Jackson" and Carter as "Sam", and they both reciprocated. Which may be excusable in a military setting as at that point Carter was a Colonel herself.
274	*** Strangely, the first time they talk, Daniel and Cam invite each other to use their first names. Neither of them ever do.
275	*** Teal'c using full names actually makes sense, as his own people have just one (unless you consider the apostrophe a divider). In his mind, he's referring to them as befits one warrior to another.
276	* On ''Series/StargateAtlantis'', it's all over the place.
277	** John Sheppard has almost everyone calling him by last name Sheppard - Best friend Rodney alternates between rank and his surname (only calling him "John" a handful of times in the entire series), Teyla combines rank and surname, Ronon just sticks with surname.
278	** Elizabeth is "Doctor Weir" to almost everyone, excluding John and Rodney, her closest and oldest friends respectively.
279	** Elizabeth and John have their own complicated system when talking to each other: They start off with a very formal 'Major' and 'Doctor', then they grow closer switching to the more intimate 'John' and 'Elizabeth' when talking to each other but keep up formal addresses in front of others. Then they just use John and Elizabeth at all times, (including in front of all of their staff and superiors and their enemies, who all refer to Elizabeth as 'Doctor Weir'). John even corrects their enemy, who's ''holding him hostage'' about how he addresses her.
280	--->'''Kolya:''' I think you overestimate Doctor Weir.\
281	'''John:''' And I think you underestimate ''Elizabeth''.
282	** Rodney is "Doctor [=McKay=]" to most people, except Sheppard and Teyla who use both "Rodney" and "[=McKay=]" equally and Elizabeth and Dr. Beckett who stick with Rodney all the time.[[note]]Of course, "Rodney" is not his first name. It's ''[[EmbarrassingFirstName Meredith]]''. When he meets an alternate version on himself, he's distressed that people call that version Rod, which he could never get anyone to call him.[[/note]]
283	** Ronon is never referred to as "Dex", at most he might get a full name "Ronon Dex".
284	** Teyla, is in fact NEVER referred to as either "Emmagan" or her full name, introductions aside obviously.
285	** All this, by the way, leaves poor fans very confused as to how they're supposed to refer to the characters.
286	* Despite being long-time partners and joined-at-the-hip best friends, ''Series/StarskyAndHutch'' simply do not use each others' first names, no matter how dire or informal the circumstances. ''[[HoYay Pet names]]'', on the other hand...
287	* ''Franchise/StarTrek''. Sure, [=McCoy=] and occasionally Spock called Kirk "Jim", but that's about it in [[Series/StarTrekTheOriginalSeries The Original Series]]. [=McCoy=] himself was sometimes known by the nickname "Bones", but no one called him "Leonard". Sulu and Uhura's first names weren't even known for decades. Chekov had his first name from the beginning, but it was only used a few times, and, of course, Montgomery Scott was "Scotty" to everyone.
288	** Nichelle Nichols stated that Gene Roddeberry himself gave her Uhura's full name, Nyota Upenda Uhura. Although none of this appeared on original series or the subsequent movies, if it came from the Great Bird of the Galaxy, It has to considered canon.
289	** In the 2009 movie she refuses to tell Kirk her first name Nyota. When Spock calls her "Nyota", Kirk asks, "So, her first name is Nyota?" and Spock interrupts with, "I have no comment on the matter."
290	** Vulcans are an interesting case: their single (pronounceable-to-humans) name usually seems to function like a surname, making it '''impossible''' to achieve FirstNameBasis with them.
291	** In ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'', Keiko would more often than not refer to her husband Miles as "O'Brien"
292	*** In private she always called him Miles; this may be a reflection of her Japanese heritage.
293	** Appropriately averted when Odo became romantically involved with Kira and started calling her "Nerys" in private. (Well, actually, given Bajoran name order, he was switching ''to'' LastNameBasis, but...)
294	** Garak the tailor is called 'Garak' by everyone. The reveal of his first name is actually Elim a major plot point of one episode. Even after that episode, everyone continues to call him 'Garak'. In one episode, when he's muttering to himself, it's clear that he even ''refers to himself'' by his last name Garak instead of his first name Elim. In the entire show, only two people ever regularly call him by his first name Elim: his mentor [[spoiler:and biological father]] Enabran Tain (who switches between Garak's first and last name depending on his moods and motives) and Tain's housekeeper, Mila whose housekeeping duties did include raising Garak. She never called him by his last name Garak [[spoiler:(and a non-canon Star Trek novel does claim she's his biological mother via a secret relationship with Tain)]].
295	** Notably averted in ''Series/StarTrekTheNextGeneration'' and newer series, however. While characters regularly refer to each other by their titles and last names while on the job, it's not at all unusual for characters who are friends to refer to each other by their first names. And then there's Seven, who is always (of necessity) referred to by her "first name".
296	*** Captain Janeway is an exception; she is usually just "Captain" or "Captain Janeway", rarely Kathryn.
297	** A blogger once did a search of the scripts of all episodes of TNG and discovered that Data addresses all other officers by their title or title and last name, ''except for [[HeterosexualLifePartners Geordi]], whom he always calls "Geordi."''
298	** An accidental characterization point in "Ensign Ro." Picard starts by addressing Ro Laren as "Ensign Laren," and she corrects him that "Laren" is actually her given name (Bajorans place the family name first) and she should be referred to as "Ensign Ro." Picard seems half indignant at being corrected by a subordinate (who is already on thin ice with the crew), half chagrined to have made such a basic error in cultural sensitivity.
299	** Seven does also have a human name (Annika Hansen) which is used during flashbacks to her as a child, or when she's hypnotized to work in a power plant, or when she's using a holodeck simulation to have a relationship with Chakotay, etc. Normally, though, she insists on being called "Seven", even when the other rescued Borg use their original names. Go figure.
300	*** She mentions at one point that while she ''was'' once Annika Hansen, she's ''been'' Seven for most of her adult life, so that is how she thinks of herself as Seven. It is actually a conceit as her full "name" was ''Seven of Nine, Tertiary Adjunct of Unimatrix Zero-One'', but when Janeway asked if they could shorten it to just Seven, she agreed, dubbing it "inaccurate, but acceptable".
301	*** Except she's no longer the "Tertiary Adjunct of Unimatrix Zero-One", having been disconnected from the Collective.
302	** In the episode "Lower Decks" (TropeNamer for LowerDeckEpisode) the lower deck characters are shocked [[note]]not [[Film/{{Casablanca}} shocked, SHOCKED!]][[/note]] when Ben (their lower deck version of Guinan) talks to Commander Riker.
303	--->'''Ben:''' Hi, Will.\
304	'''Riker:''' Ben. How you doing?\
305	'''Lavelle:''' You call him Will?\
306	'''Ben:''' Why not?\
307	'''Lavelle:''' He's second in command of this ship, that's why not.\
308	'''Ben:''' I'm not Starfleet, I'm a civilian. When he's in here, he wants to be treated like a civilian.\
309	'''Lavelle:''' Riker? I bet he sleeps in his uniform.
310	** Justified in the case of Jadzia Dax in ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'', where we learn that Joined Trills take the name of their Symbiote as their surname, which replaces their original one. Only Sisko, Kira, Worf, and Bashir occasionally call her Jadzia.
311	* ''Series/StElsewhere'': Helen's children half-jokingly refer to each other by their respective fathers' surnames since their mother is a SerialSpouse: Marcy (Eisenberg), Julie (Silverman 1), Jimmy (Silverman 2), Erin (Scheinfeld) and Jeff (Rosenthal).
312	* ''Series/{{Supergirl\|2015}}'': Even after Alex and Maggie start dating, Maggie calls her girlfriend "Danvers". Alex uses Maggie's first name, though.
313	* ''Series/TedLasso'': Coach Beard is always called "Beard" by everyone, including his best friend and girlfriend. It's revealed in the finale that his first name is Willis.
314	* "Stiles" Stilinski of ''Series/TeenWolf'' is only Stiles. Even his father calls him Stiles. Perhaps because his given name is bizarre and apparently near-unpronounceable. [[spoiler: It's the Polish name Mieczysław.]]
315	* ''Series/That70sShow'':
316	** Most people call Steven Hyde by his last name, except Kitty, Red, and (once they started dating) Jackie.
317	** Kitty and Jackie are also the only ones who call Michael Kelso by his first name.
318	** Hyde almost always refers to Eric as "Foreman", sometimes even when talking to Eric's parents. The other characters alternate between his first and last names.
319	%%* That's 80's Show June Tuesday is known commonly called by her surname Tuesday
320	* The [[Creator/ChristopherTitus titular character]] of ''Series/{{Titus}}'' was referred to as "Titus" by everyone except his girlfriend and his father. Titus often even referred to himself by his last name Titus.
321	* In ''Series/TJHooker'', everybody calls him 'Hooker'. Even his ex-wife. His given name, Thomas, was only mentioned once in the entire run of the series, and never again after that.
322	* On ''Series/TopGearUK'', presenter Richard Hammond is always "Hammond" to his co-presenter James May, but Jeremy Clarkson is "Jeremy" or even "Jezza" (unless May is annoyed with him, in which case it's "CLARKSON!") On the other hand, Clarkson and Hammond are on a first-name basis with each other and with May.
323	** They all refer to each other with their last names fairly often, especially when communicating over the phone/radio on a large challenge or race e.g.: "May!" "Clarkson!" "Where are you and Hamster?" "We're just entering Switzerland, what about you?" as mentioned in the Real Life section, this is quite common between male friends in Britain where the surname almost becomes a nickname of sorts.
324	* ''Series/{{Trigonometry}}'': Moira always calls Ray Wilson, her last name.
325	* ''Series/{{Voyagers}}'': Jeffrey always refers to Bogg by his surname, never as Phineas or anything else, which gets pretty odd during highly emotional moments.
326	* ''Series/WelcomeBackKotter'':
327	** Most of the Sweathogs go by their last name.
328	** The expectation that all students refer to their teachers by a courtesy title and their last name is addressed briefly (and effectively) in the Season 2 episode "Sweathog, Nebraska Style", when Gabe's teenaged sister-in-law, Jenny, who is temporarily staying with him and Julie, temporarily joins the Sweathogs. Jenny is being obnoxious and, as he tries to call the class to attention, she calls him by his first name, prompting him to immediately call her on it ("In class, I am Mr. Kotter").
329	* A rare aversion, given its professional setting, occurs in ''Series/TheWestWing''. The entirety of the central cast refer to one another by their first names (though "CJ" is obviously a nickname, her full name is heard numerous times). The only real exceptions are the President himself - who is occasionally addressed with his first name by either his wife or very close friends, and even then usually in private - and Mrs. Landingham.
330	** It is strongly suggested that the reason why Mrs. Landingham isn't on a FirstNameBasis with everyone is because all the staff are following the President's example: when the two first met, he was a high school student and she was his father's secretary; he once tried to call her "Dolores" and she insisted "Mrs. Landingham, please" - and he stayed on a LastNameBasis with her ever since, even after becoming President.
331	** Aside from the above flashback, the only other time the President calls her Dolores is [[spoiler: just before she dies]], asking her if she had ever bought a new car in her life.
332	* On ''Series/{{Wings}}'', Roy usually refers to everyone using their last names. (Unless he's trying to suck up to them for some reason.)
333	* ''Series/TheXFiles'':
334	** Mulder and Scully regularly called each other by last name. Once Scully's mother referred to Mulder as Fox and Scully corrected her -- it didn't stop Mrs Scully though. In the first four seasons, they'd occasionally use first names at emotional moments, but after that they just gave it up, apparently having gotten so used to the last names that "Fox" and "Dana" just sounded weird. In the second movie, [[spoiler:they've had a RelationshipUpgrade and have been living together for six years]], and they're ''still'' on a Last Name Basis.
335	** Becomes a plot point a couple of times, when lookalike impostors falsely assume that with a relationship as close as theirs, the two agents ''must'' be on FirstNameBasis. In fact, it may be the ProperlyParanoid agents' unspoken [[CrazyPrepared security measure for such situations]].
336	** The Lone Gunmen, a trio of Mulder's friends and conspiracy nuts, also go for last name basis (Frohike, Langley, and Byers).
337	** Noticeably averted by Agents Doggett and Reyes, who are on a FirstNameBasis with each other after they met while solving the murder of Doggett's son years prior. They only refer to each other as "Agent Doggett" or "Agent Reyes" around other agents.
338	* In ''Series/TheYoungAndTheRestless'', Philip Robert Chancellor IV plays with this trope, as everyone commonly calls him "Chance", the short version Of his last name.
339	* In ''Series/YoungBlades'', D'Artagnan's first name is never revealed, and even his ''father'' (the D'Artagnan from ''Literature/TheThreeMusketeers'') calls him D'Artagnan.
