In TheWildWest, a man had to grow up fast if he wanted to survive. Quite a few gunslingers and outlaws made their reputation before they were even old enough to shave regularly. Thus, they got "Kid" as part of their nickname. Given the lethality of their professions, few lived long enough to have this become an embarrassing name.

The naming convention is referenced in settings outside TheWildWest as well, particularly in boxing, and ProfessionalWrestling.

!!Examples:

[[AC:{{Western}}s]]
* The desperado that Yancey has to shoot in ''Film/{{Cimarron}}'' is named, simply, "The Kid".
* ''Series/TheCiscoKid'': The title character, played by Duncan Renaldo, was a Mexican cowboy. There was also a series of movies starring Cisco and his comic sidekick, Pancho.
* ''Series/AliasSmithAndJones''' Kid Curry.
* Rawhide Kid, the Two-Gun Kid, the Ringo Kid (not related to John Wayne's Ringo Kid in ''Film/{{Stagecoach}}''), the Apache Kid, the Arizona Kid, the Prairie Kid, the Texas Kid, the Western Kid, the Gunsmoke Kid, the Dakota Kid and (in a slight variation) Kid Colt, all from MarvelComics. According to StanLee, Marvel publisher Martin Goodman loved Westerns, and was ''particularly'' fond of this trope for some reason.
* The Literature/TimeWars book ''The Six-Gun Solution'' had a time-traveling character acquire the nickname "The Montana Kid".
* The babyfaced Creator/AudieMurphy played youthful outlaws and adventurers so often that he joked once that he'd "kidded his way through the movies." Relatively few of his thirty-plus western characters have The Trope Kid nicknames, though: Billy the Kid in ''The Kid From Texas'', The Cimarron Kid in the film of the same name, The Silver Kid in ''Duel At Silver Creek'', and The Utica Kid in ''Night Passage''.
* The Schofield Kid in the movie ''Film/{{Unforgiven}}''.
* The Sundance Kid from ''Film/ButchCassidyAndTheSundanceKid''.
* Creator/DCComics character the Wyoming Kid.
* In the film, "An American Tail: Fivel Goes West"--the title character originally imagines himself as a gun-slinging hero with an already known moniker: "Billy the Kid."
* Might count under Parodies as well, but in ''ShanghaiNoon'', Creator/JackieChan's character is listed on a wanted poster as "The Shanghai Kid." His partner notes, "That's a really cool nickname, too." Jackie's character immediately complains that he's not really from Shanghai.
** In a possible ShoutOut, ''WesternAnimation/JackieChanAdventures'' featured a {{flashback}} to a [[IdenticalGrandson suspiciously familiar-looking ancestor]] of Jackie's in [[TheWestern the Old West]] nicknamed "The Hong Kong Kid". Amusingly enough, Chan is from Hong Kong, so the cartoon comes one step closer to RealLife.
* The Sundown Kid of ''LiveALive''.
* The Ysabel Kid from JTEdson's ''Floating Outfit'' series.
* Fee 'The Kid' Herod of ''Film/TheQuickAndTheDead''
* The titular character from ''TheDurangoKid'', played by Charles Starrett. Between 1940 and 1952, there were 64 movies made featuring the Durango Kid.
* In ''Film/LittleBigMan'', Jack Crabb is known as the Soda Pop Kid during his "gunfighter period".
* The Brimstone Kid from ''YoungbloodJudgmentDay''. He was a gunslinger who sold his soul to the devil in exchange for unbeatable gunslinging skills.
* Creator/RobertEHoward's 'The Sonora Kid'.
* Subverted in Creator/KarlMay's westerns. Anytime someone makes a name for themselves in the West, young or not, they get a moniker with "Old" slapped on. Old Shatterhand, Old Surehand, Old Firehand etc.

[[AC:Non-{{Western}}]]

* TroperTales: HeartBurnKid and EponymousKid.
* "Kid Death" from a series of pulp short stories was a {{Gangster}} variant on this trope, so called because of his youthful appearance and the tendency of corpses to appear whenever he was around -- not all by his hand.
* Death the Kid from ''Manga/SoulEater'', and his [[TheGunslinger Gunslinger]] ways are clearly inspired by this idea. He is the son of the GrimReaper too.
* Stephen King's novella, ''The Colorado Kid'' is not Western, but rather a semi-detective tale.
** And his book TheStand had a character known just as "The Kid".
* Superheroes: [[ComicBook/{{Legion Of Super-Heroes}} Invisible Kid, Karate Kid, Kid Quantum]], [[JusticeSocietyOfAmerica Star-Spangled Kid]], [[TheFlash Kid Flash]], [[Comicbook/TeenTitans Kid Eternity, Kid Devil]], [[ComicBook/{{X-Men}} Kid Omega, Kid Vulcan]], Kid [[strike:Marvelman]] Comicbook/{{Miracleman}}...
* ''The Cincinnati Kid''

** Also the name of a 1985 song by [[http://en.wikipedia.com/wiki/Restless_Heart Restless Heart]] actually called Back To (The Heartbreak Kid)
* ''{{Eyeshield 21}}'': Musyanokoji Shien, the quarterback of the {{Western}}-themed Seibu Wild Gunmen, is [[OnlyKnownByTheirNickname usually only referred to as "Kid"]]. Also an IronicNickname, since he has an [[YoungerThanTheyLook old man's face]].

* The MythAdventures novel ''Little Myth Marker'', being a parody of gambler tropes, gives us the Sen-Sen Ante Kid (he always includes a breath mint in his stake for good luck). Subverted in that he's an old fat guy who got the nickname a loooooong time ago.
