History NoNameGiven / LiveActionTV

* The titular character of ''Series/TheMandalorian'' is never referred to by name, people calling him just "Mandalorian" or "Mando", until the 1st season finale [[spoiler: when the BigBad calls him Din Djarin, revealing himself as the Imperial agent responsible for the purge of Mandalore.]]

** Spin-off literature has revealed that the Wraiths' names for each other are more based on telepathic communication that doesn't always translate well into spoken language; as an example, the Wraith Todd's true name in Wraith culture essentially translates to mean 'Guide', with Wraith Queens being referred to by names such as 'Waterlight' and 'Alabaster', while John Sheppard is also referred to as 'Guide' due to his name and his similar status among the Atlantis expedition compared to Guide's role.

* [[TheUnreveal Not revealing]] Mrs. Doyle's first name became a RunningGag in ''Series/FatherTed''. At one point, she said it three times, but was drowned out by [[SoundEffectBleep a convenient noise]] each time. However, it's revealed early on as Joan, which the scriptwriters regretted.

* ''Series/TheOutpost'': The Smith (or The Wolf) and The Mistress are never called by their real names.

** Although he appears in every scene of "The Light Brigade", the cadet is never named.

** In "Decompression", the Time Traveler is not named.
** In "The Grid", the young girl who tells Scott Bowman about the computer controlling the people of Halford is not named.

** Various Time Lords only go by titles, such the ArchEnemy Time Lord the Master and minor Time Lord enemies the Rani, the War Chief, and the Monk. The latter four have had their names revealed in the ''Franchise/DoctorWhoExpandedUniverse'' ([[spoiler:The Master — Koschei, the Rani — Ushas, the War Chief — Magnus, the Monk — Mortimus]]) but not the Doctor.

* The sketch comedy ''Series/AlmostLive'' regularly features "Mind Your Manners", kung-fu parody skits in which the hero Billy Quan always delivers a beat-down on the same unnamed and unrepentant Jerkass (played by the show's host John Keister.)

* On ''Series/StarTrekVoyager'', The Doctor (the Emergency Medical Hologram, not [[Series/DoctorWho that one]]) went seven years without getting a name that stuck. In the last episode, he's portrayed as finally having settled on "Joe", but that was in a future that got erased. [[note]]WordOfGod is that he was originally named Dr Zimmerman in the script, but they managed to go long enough without mentioning his name onscreen that it became a plot point of its own.[[/note]]

** Sparky's real name is never revealed. Not his first name, but he's Staff Sergeant Pryor (as shown in the Season 1 episode "Tuttle").

** [[Recap/DoctorWhoS30E8SilenceInTheLibrary "Silence in the Library"]]/[[Recap/DoctorWhoS30E9ForestOfTheDead "Forest of the Dead"]]: The mysterious little girl and her dad are never named. [[spoiler:The second episode reveals the girl's name to be Charlotte Abigail Lux, but her dad's name — if he ''is'' a representation of her father, since she underwent BrainUploading a long time ago — isn't mentioned.]]

** The X-Files was full of this trope, many of the main conspirators are never named and are often known solely by the descriptive terms used in the credits. There's Mr. X, The Well-Manicured Man, The Grey-Haired Man, Second Elder, Third Elder, Toothpick Man, Quiet Willy, The Red-Haired Man, and so on and so forth.

* Creator/TheBBC made a documentary about the research centre [[https://en.wikipedia.org/wiki/Porton_Down Porton Down]], which is one of the most secret sites in Britain. The site director was the only person interviewed whose surname was shown, and it is possible that "Alan", "Marcus" and "Cerys" were not those people's real names.

* The protagonist of ''Series/{{Fleabag}}'' is never named. Although "Fleabag" is used as the character's nickname in publicity, even that's never used in-universe, and the credits simply say "starring Phoebe Waller-Bridge" without calling her character anything at all. Many of the other major characters go unnamed as well, being given nicknames or simply descriptions like "Godmother" and "The Priest".

* The protagonist of ''Series/{{Fleabag}}'' is never named. Although "Fleabag" is used as the character's nickname in publicity, even that's never used in-universe, and the credits simply say "starring Phoebe Waller-Bridge" without calling her character anything at all.

** None of the characters in "[[Recap/TheOuterLimits1995S3E7TheCamp The Camp]]" are named. The android overseers seemingly don't have names, while the human slaves are referred to by serial numbers. [[SubvertedTrope However]], two of the slaves are given the names Tali and Alex in the sequel "Promised Land".

* ''Series/TheOuterLimits1995'': In "[[Recap/TheOuterLimits1995S5E7TheHumanOperators The Human Operators]]", neither the man nor the women appear to have names. Ship only refers to her as "the female". The man's father is also never named. He simply calls him "my father".

* On TV and in the radio, ''Franchise/TheLoneRanger'' was this trope. We know his last name was Reid, like his brother and great grand-nephew ''Franchise/TheGreenHornet'', but we never learn his first name in those versions. It is given as 'John' in later media. In the final chapter of the 1938 Republic The Lone Ranger movie serial, he is revealed to be Texas Ranger Allen King. In the second serial, The Lone Ranger Rides Again, he identifies himself as "Bill Andrews".

** The Cigarette Smoking Man is later referred to by the name [[spoiler: C.G.B. Spender]], though Scully believes it's just an alias and not his real name.
