4	In RealLife, identical twins are still often different enough to be distinguishable. In Fictionland, this isn't always the case. Many times a twin will be mistaken for their sibling, whether or not they [[AllegedLookalikes realistically would be.]]
5
6	This may happen intentionally, as part of a FakeTwinGambit, a TwinSwitch, or if a character is ImpersonatingTheEvilTwin, but just as often it's a complete accident, with [[HilarityEnsues hilarity following]]. However, this can also be used for drama, if the mistake leads to an actual problem rather than a gag; this route is common when one twin is a criminal. If the twins are babies, expect this to happen often. This trope is also an obvious common outcome of [[TwinTest Twin Tests]] as the siblings explicitly ask others to point out who is who.
7
8	Contrast IdenticalTwinIDTag, where the twins make a conscious effort to avert this trope. Compare AmbiguousCloneEnding, where the characters and the audience is left unsure who the clone is. Also compare IdenticalStranger and InexplicablyIdenticalIndividuals, who may also be confused for each other. Supertrope to TwinSwitch and ImpersonatingTheEvilTwin, as those tropes rely on this confusion to work.

17	[[folder:Anime & Manga]]
18	* ''Manga/OuranHighSchoolHostClub'': The only person who can tell the Hitachiin twins from sight alone is Haruhi. Everyone else struggles, not helped by the twins' tendency to [[TwinSwitch switch their identities]], mostly for laughs. After his CharacterDevelopment, however, Hikaru decides to dye his hair black to differentiate himself from Kaoru. The anime makes this a case of AllegedLookalikes, because even though the twins have the same appearance, their voices are ''completely'' different (Kaoru has a much softer voice than Hikaru).
19	* In ''Manga/TheQuintessentialQuintuplets'', when Fuutarou and the Nakanos all end up in class 3-1 together, it's shown in chapter 70 that their classmates are even worse at telling the quintuplets apart than Fuutarou is. This leads to situations like a pair of girls trying to bring one of the sisters to a teacher and grabbing the wrong one by mistake (three times in a row!), or other students asking Fuutarou to pass a message/item to a quint [[RightInFrontOfMe that's standing right next to him]].
20	* ''Manga/ZekkyouGakkyuu'': Nana and Nono from ''The Story About Twins'' get mistaken by sight alone despite them having different haircolors.
21	* ''Manga/TheDukeOfDeathAndHisBlackMaid'': When they first meet Daleth, both Nico and Ichi mistake her for Sade. Since both of them had played a hand in her death, they conclude she must have returned Back From The Death somehow. Daleth, for her part, plays along for a bit in order to gain information, but desists when she overhears their battle might threaten Walter.
22	[[/folder]]
23
24	[[folder:Asian Animation]]
25	* ''Animation/AditDanSopoJarwo'': "Saudara Berkunjung Semua Tersanjung" has Jarwis, Jarwo's much nicer twin, comes to the suburb and gets mistaken for Jarwo. Those who sees Jarwis is confused at seeing Jarwo being generous and polite until it gets cleared up at the end of the episode.
26	[[/folder]]
27
28	[[folder:Comic Books]]
29	* One instance of ComicBook/GreenArrow meeting ComicBook/BlackCanary has him saying that he's had a huge crush her for years. Black Canary is offended because he's talking about [[LegacyCharacter her]] [[StrongFamilyResemblance mother]].
30	* ''ComicBook/GravityFallsLostLegends'': When Pacifica first saw Ford, she assumed he was Stanley, though she notices that he looks very different. The comic ends before we see if anyone explained the truth to her.
31	* ''ComicBook/{{Supergirl}}'':
32	** In ''ComicBook/StarfiresRevenge'', Supergirl mistakes Rodney Marlowe for his twin brother Derek. Much to her confusion because Derek was reported dead.
33	** In ''ComicBook/SupergirlSpecial'', a security guard mistakes Power Girl for her alternate self Supergirl when he is rescued by the former.
34	* ''ComicBook/WonderWoman'': The Heyday triplets (three of the Holliday Girls) are identical and are commonly mistaken for each other even when they're not pulling a TwinSwitch, which leads to them being ordered to wear name tags. They generally avoid the name tags, which comes in handy when their vile elder brother abducts them to make them sign over their inheritances. It doesn't work because he can't tell which one should be signing which name.
35	[[/folder]]
36
37	[[folder:Fan Works]]
38	* PlayedForDrama in the ''Franchise/{{Pokemon}}'' fanfic ''[[https://archiveofourown.org/works/40609707 Airplane Mode]]''. After going missing for years, Subway Boss Ingo returns to Gear Station, where he is mistaken for his identical twin brother, the other Subway Boss Emmet. Specifically, a senior Depot Agent thinks that Emmet pretends to be Ingo to cope with his death, and begs him to take the week off. Ingo proves that he's not Emmet by having the agent call his phone.
39	* Features in the Modern AU ''WesternAnimation/HowToTrainYourDragon'' fic ''[[https://www.fanfiction.net/s/13122923/1/Confusion Confusion]]'', as Astrid and her OC twin sister Lillian start dating Hiccup while involved with each other; initially all three were unaware that the sisters were dating the same person while Hiccup assumed that he was dating one girl who acted differently in clubs and on campus, only realising that there were two of them when he was invited to their apartment. After they settle into a triad relationship, as part of their efforts to stop their mother finding out that Hiccup is dating both girls, at one point Lillian pretends to be Astrid when their mother comes to the sisters' flat while Astrid is out (their parents having been told Hiccup is 'just' Astrid's boyfriend).
40	* ''Fanfic/TheBridge'': The Sirens and Dark Hunters get a bone to pick with Twilight Sparkle after she allies with the dark magic source the Hunters are going after along with stealing Sonata Dusk's necklace, leaving her scarred and sickly. This causes Monster X to threaten the resident Rainbow Dash, knowing it would draw the hiding Twilight out. So when ''Princess'' Twilight Sparkle arrives after being summoned by Sunset Shimmer, it's not even two hours into her arrival when Monster X and Gigan ambush the party and kidnap her to demand information and the return of the necklace. Problem? She has no idea what they are talking about. It's only after discussion they realize it was the human world's resident Twilight Sparkle that was responsible.
41	* ''Fanfic/ACertainDrollHivemind'': Since the Sisters normally wear the Tokiwadai Middle School uniform, when Touma sees a girl who looks like Misaka Mikoto wearing different clothes, he assumes it's Mikoto. It's actually Misaka-11111, who got dragged out clothes shopping because her flatmates were annoyed at her wearing the uniform of a school she didn't even go to.
42	-->"'I am not Misaka Mikoto. I am Misaka-11111,' Misaka repeats," I tell him again.\
43	"But you're wearing different clothes," he protests. He does not appear to understand that we have the capacity to wear clothes that are not Misaka Mikoto's school uniform. We are not sure if Kamijou Touma has ever approached Misaka Mikoto when she is on her way to school under the impression that she is one of us. Statistically, if you see someone who looks like Misaka Mikoto wearing the Tokiwadai uniform, you should assume that they are a member of the Network. The chance that they are the original can be discounted as statistical noise.\
44	We suspect he would probably realise his mistake quite quickly. The original would probably not appreciate it.

48	[[folder:Film-- Live-Action]]
49	* ''Film/{{Assassination}}'': Kang In-guk, an evil member of LesCollaborateurs in league with the Japanese, kills his long-lost daughter Ok-yun, because she is a member of LaResistance fighting against the Japanese. Except, he actually killed his ''other'' daughter, Machiko, the one who wasn't separated at birth and wasn't fighting for Korea or plotting against him. Ok-yun proceeds to assume her dead sister's identity and infiltrate her father's household so she can get another shot at murdering him.
50	* In ''Film/DoubleImpact'' Jean Claude van Damme plays twins. They are at first mistaken for each other, but they have very different personalities and are soon told apart.
51	* The twins from the ''Series/{{Firefly}}'' movie ''Film/{{Serenity}}'' try to invoke this by pulling the TwinSwitch on people for fun. They're frustrated that [[TheCaptain Mal]] can always tell which is which.
52	-->'''Mal:''' Mingo. ''[Nods to Mingo]'' Fanty. ''[Nods to Fanty]''\
53	'''Mingo:''' He's Ming-\
54	'''Mal:''' He's Fanty, you're Mingo.\
55	'''Mingo:''' ''[Stares at Mal for a moment before reluctantly smiling]'' How is it you always know?
56	-->'''Mal:''' Fanty's prettier.
57	-->'''Fanty:''' ''(smirks at Mingo)''
58	* ''Film/TwinDragons'' stars Creator/JackieChan as twins, SeparatedAtBirth. One is raised in a wealthy family and grows up as a music conductor, the other is adopted by a homeless woman and becomes an asskicking badass, typical Jackie Chan style. For the climax, guess ''which'' Jackie gets captured by baddies and ''which'' gets mistaken as a musician and forced to perform onstage, in front of a thousand audiences.
59	* ''Film/TwinSistersOfKyoto'': Hideo meets Naeko when he accidentally gives her the obi (a kimono's sash) that he weaved for Chieko. (Hideo does not know about Naeko because Naeko and Chieko were SeparatedAtBirth.)
60	[[/folder]]
61
62	[[folder:Literature]]
63	* ''Literature/FoxDemonCultivationManual'': The real [[spoiler: Feng Zhuojun]] died years ago. The man Jiang Liang thought was [[spoiler: Feng Zhuojun]], the one who got married and apparently betrayed Jiang Liang, was actually his twin brother.
64	* In ''Literature/TheChroniclesOfNarnia'' novel ''Literature/TheHorseAndHisBoy,'' protagonist Shasta is suddenly grabbed off the street by the Narnian royalty, who think that he's Prince Corin of Archenland. Shasta stays with them and hears some plot-significant information before being left alone...at which point the identical Prince Corin climbs in through the window, having sneaked out to explore the city. By this point we've established that Shasta knows nothing about his birth family, so you can probably figure out [[LongLostRelative the twist]].
65	* This sometimes happens with [[TricksterTwins Fred and George Weasley]] from ''Literature/HarryPotter'', even by their own mother. Often it's because the twins themselves pretend to be each other just to {{troll}} others.
66	* In ''Literature/{{Flawed}}'', this is downplayed, occurring between sisters that look alike, but are months apart in age. Celestine, who was branded as "flawed", still has to go to her high school while marked, forced to always wear a red arm band. Her similar-looking older sister Juniper is one day photographed from behind, mistaken for Celestine, and since Juniper doesn't have a band, everyone thinks Celestine broke the rules. This causes Celestine to be expelled from school.
67	* In ''Literature/TheFolkOfTheAir'' faeries repeatedly have issues telling Jude and Taryn apart. Locke, having wooed both of them, is so bad at differentiating the two that when Jude attempt to threaten him and tell him to treat Taryn well, he initially assumes Taryn has randomly become violent with him. Cardan even goes so far as to suggest that Locke couldn't tell which was which when he first tried to court Taryn, and it was chance that Taryn ended up being the first twin he approached. Taryn also takes advantage of how few people can tell them apart (as well as the fae rarely taking into consideration that humans [[CannotTellALie are capable of lying]]) to claim to be Jude in order to take advantage of her status.
68	* The TwinSwitch in ''Literature/LottieAndLisa'' is so successful that the girls are only found out by complete coincidence. They look exactly alike except for their hairstyles which are easily disguised. However, they are also PolarOppositeTwins and have to work hard to maintain their charade, which causes especially Lotte a lot of stress and anxiety. They would probably have been found out due to their different personalities and lack of knowledge about each others' lives had it not been for the fact of the parents being distracted by their own problems. Their looks, however, are so identical that they themselves cannot distinguish between each other in a photo.
69	* In ''Literature/TheRollingStones1952'' Castor and Pollux, 'the Unheavenly Twins', use this to trick their teachers, with one twin taking two identical classes.
70	* In the ''Sophie'' books, not only do the twins Matthew and Mark pretend to be each other sometimes, but they often get mistaken for each other.
71	* In the first book of ''Literature/SweetValleyHigh'', bad girl Jess goes to a dive bar and gets involved in a fight. The cops mistake her for her more innocent twin sister, Liz, causing Liz to be the butt of rumors at school. This actually happens repeatedly throughout the series, to dangerous levels--Jessica's stalker kidnaps Elizabeth by mistake, while a guy stalking Elizabeth because [[HeKnowsTooMuch she witnessed him committing a crime]] abducts Jessica.
72	* In a ''Sweet Dreams'' book, a girl runs into the guy she met a few days ago and happily chats with him, not understanding why he seems weirded out by her behavior. When she runs into him again and blasts him for his rudeness, he realizes that it's his twin she was talking to and that his attitude was because he thought she was coming on too strong (oddly, at no time did it occur to him that she'd simply mistaken him for his brother).
73	* Gareth and Gaheris in ''Literature/SwordOfTheRightfulKing'' are physically identical and can only be differentiated by behavioural quirks. Their older brother Gawaine is one of the few people who can reliably tell who's who.

76	[[folder:Live-Action TV]]
77	* ''Series/AllMyChildren'''s Adam Chandler would often deliberately invoke this, pretending to be his good twin Stuart, usually to pull off some nefarious act, occasionally dragging Stuart into it against his will.
78	* ''Series/ArrestedDevelopment'':
79	** Happens repeatedly in the episode "The One Where Michael Leaves" with the police mistaking Oscar for his fugitive twin brother George. [[spoiler: Except the last time when George deliberately disguises himself as Oscar to invoke this.]]
80	** Invoked again in "Righteous Brothers" when George [[spoiler: gets Oscar sent to jail in his place.]] The following episode reveals that "You've got the wrong twin" is a very common retort to the police.
81	* ''Series/TheBarrier'': Hugo is recently widowed from Sara, a woman who had an identical twin sister named Julia. At some point in the series, Hugo and Julia walk by a closed-down night club style bar that they both recognize. Hugo tells Julia the bar is the place where he first saw Sara and fell in love with her, but didn't manage to approach her or get noticed by her, resulting in him first asking Sara out after running into her again somewhere else. In Hugo's flash-back to when he first saw Sara, a pendant necklace of which the twins owned identical versions that differed only in color is hidden under Sara's top and Sara is wearing braids, which are favored by Julia. Julia is also surprised that Sara would ever go to that bar, as they were TomboyAndGirlyGirl twins to an extent and Sara was the girly girl. Guess who Hugo actually saw in the bar that evening.
82	* The title character of ''Series/{{Columbo}}'' once used this to trick a murderer into incriminating himself. The murderer had almost run over a blind man while fleeing from the scene of the crime. Later, Columbo brought in what appeared to be the same blind man to identify the murderer. The killer protested that the man was blind. Then Columbo asked why the killer would think that, since when the man he had brought in wasn't wearing dark glasses or carrying a white cane. The killer claimed that as a trained physician he could spot subtle clues. Then Columbo had the "witness" read from a newspaper. The "witness" was the blind man's identical twin brother, and by claiming the witness was blind the killer showed that he had mistaken the man for the blind man who was almost run over.
83	* The final moment of one episode of ''Series/CriminalMinds'' reveals that they arrested the wrong person, with the closing quote being "There are only two things in life that are ever unexpected. Twins." The next episode clarifies that the unsub and his brother were [[SeparatedAtBirth separated as toddlers]] and even the unsub himself didn't know he had a twin brother. The arrested twin, Jesse, had insinuated himself into the investigation as part of a plan to make contact with the guilty twin, Wallace (and eventually KillAndReplace him). After the brothers have met, a coworker of Jesse sees Wallace leaving Jesse's house and assumes it's Jesse. He's too freaked out to correct her, so he just runs away.
84	* One episode of ''Series/{{CSI}}'' deals with the VictimOfTheWeek being a soccer mom that was shot in a parking lot, and the investigation eventually leading to a house where the woman's identical twin has apparently hanged herself. Turns out that the women were long-lost twins and the one who apparently committed suicide had become a newspaper editor and was about to rat out a photographer that had photoshopped pictures of the Second Gulf War to "make them more representative of WarIsHell", winning a prize for that. He had seduced her, drugged her and hung her, and seeing her twin made him believe that she had ''somehow'' survived that and shot the twin just to make sure.
85	* On ''Series/Deception2018'' identical twins Cameron and Johnny Black have been using the TwinSwitch as part of a magical act for most of their lives. Very few people know that Johnny exists which allows them to do spectacular teleportation tricks eg. Cameron disappears in an explosion on stage in Las Vegas and Johnny then appears on a similar stage in Times Square in New York City. In the series premiere Cameron is arrested for a crime committed in New York City and realizes that the police have mistaken him for Johnny. Once the twins' secret is revealed to the world, Johnny is sent to prison and Cameron tries to prove that he was framed. Once Cameron confronts the Mystery Woman behind the frameup ,she realizes that she framed the wrong brother. She once met Johnny but mistook him for Cameron and when she wanted to recruit him for her scheme, she framed the other twin to get him out of the way. She is quite annoyed when she realizes that she got the wrong brother sent to jail.
86	* ''Series/{{Friends}}'': As part of the shared universe with ''Series/MadAboutYou'', Lisa Kudrow plays both Phoebe and her twin sister, Ursula, who happens to be a character in the other show. This is joked about when the cast of ''Mad About You'' show up at Central Perk, and thinking Phoebe is actually Ursula, assume she's a waitress at the cafe (just as Ursula is a waitress at their local restaurant) and tell her their orders. Phoebe, naturally, is confused by this.
87	* ''Series/HouseOfAnubis'': When Patricia's [[PolarOppositeTwins polar opposite twin]] Piper arrives at the house, this trope is in full force. Apart from their TwinSwitch, Piper is mistaken for Patricia multiple times. This leads to Eddie kissing her, Alfie thinking his crush on Piper is a crush on Patricia, and the Sibunas thanking "Patricia" for getting rid of the stolen oxbow before the teachers checked her bag. Strangely, they did have an IdenticalTwinIDTag with their necklaces. After Piper gives Patricia hers before leaving, Eddie then mistakes Patricia for Piper.
88	* ''Series/{{iCarly}}'': In the episode where Sam's [[PolarOppositeTwins polar opposite twin]] Melanie is introduced, Freddie spends the entire episode thinking that Melanie doesn't exist, and is just Sam screwing with him. As the two are never seen together until the very end, the episode is set up so that the viewers are just as uncertain as Freddie.
89	* A particularly heartbreaking version forms the basis of an episode of ''Series/LawAndOrderSpecialVictimsUnit''. A woman who had an identical twin threatened to report a crime syndicate to the cops because they were holding another sister hostage. A member of the syndicate went to her apartment to kill her, on the same night that it just so happened the other twin had come by looking for her sister. When the assassin found her there, he mistook her for his target and killed her.
90	* An episode of ''Series/NashBridges'' involves a pair of twin brothers, one of whom is a city official while the other is a criminal. At one point, Bettina arrests the criminal, but lets him go when he claims to be the city official. Soon after, Bettina encounters the official and arrests him despite his protests. Being an idiot, Bettina doesn't ask for proof of identity either time.
91	* In ''Series/MurdochMysteries'', this is a long-running subplot in Season 14: Having been kidnapped by the AxeCrazy StalkerWithACrush Amelia, Crabtree is horrified when he thinks he sees the same woman working as his girlfriend's secretary under an assumed name. She explains that she's Amelia's twin sister Dorothy, but given how good Amelia was at creating false narratives that she would believe herself, Crabtree is unconvinced. It eventualy turns out [[spoiler: that she's telling the truth ... but she and Amelia are working together.]]
92	* ''Series/SesameStreet'': Played with. Chip and Dip are brothers, and are probably from the same litter since they once mentioned learning to talk around the same time, though it's unknown if they are twins or if there were more of them. Nevertheless, when Oscar firsts meets them, he thinks they're both the same cat popping up.
93	* Happens several times over the course of ''Series/SisterSister'', especially in the earlier seasons. For example, in the first episode, SeparatedAtBirth twins Tia and Tamara coincidentally meet at the same store. One is looking for a sweater and the other is looking for a sweatshirt. They take turns asking the same sales clerk, who doesn't realize there are two of them and slowly goes crazy with them for constantly "changing their minds." Considering ''they'' didn't even know they were twins yet, a complete stranger couldn't be expected to know either.
94	* ''Series/TheSootyShow'': When Sweep's twin brother Swoop visits in one episode, Soo and Matthew initially mistake him for Sweep.
95	* ''Series/TheSuiteLifeOfZackAndCody'': Downplayed. For the most part, the twins manage to avoid this trope, but one episode has them doubt their identities when they see a video of their mother getting them confused when they were newborn babies.
96	[[/folder]]
97
98	[[folder:Radio]]
99	* In the Chilean radio program ''El Chacotero Sentimental''[[note]]A LongRunner program in which people confess anonymously their love/sex stories for the audience and the presenter gives them advices[[/note]], there was a case of a guy who had a girlfriend and she has a twin sister. He tells about his relationship with his girlfriend but then sometimes he noticed his girl acted very different, to noticed time later she made TwinSwitch with her sister, so he basically was dating both sisters without noticing it.

101
102	[[folder:Video Games]]
103	* A meta-example occured with ''VideoGame/AnimalCrossingNewHorizons'' with the dodo twins Wilbur and Orville, the only physical difference between them being that Wilbur wears CoolShades. While they aren't mistaken for each other in-game, Creator/{{Nintendo}} themselves made this mistake in the initial release of the 2.0 update. Inviting characters to the photo studio unlocks a poster of them, but in the dodos' case, [[GoodBadBugs inviting one twin would unlock the poster of the other]]. This was confirmed to have been an actual mistake and not a tongue-in-cheek joke when it was fixed in the 2.02 patch.
104	* In the second ''VideoGame/{{Boktai}}'' game, during the mission in the Remains, Django gets mistaken by Kid for his twin brother Sabata, who saved Kid earlier in the story. (How this could happen is confusing, considering that both twins have distinguishable hairstyles and hair and eye color).
105	* ''VideoGame/FinalFantasyXIV'' has the HalfIdenticalTwins Alphinaud and Alisaie Leveilleur who do look very alike despite being the opposite gender and people often confuse them.
106	** Whilst they go through a TwinDesynch over the course of the second expansion (''Stormblood'') which prevents this for most people - this doesn't stop Estinen, who met Alphinaud alone in the first expansion (''Heavensward'') from mistaking them when he meets Alisaie for the first time between the fourth (''Shadowbringers'') and fifth (''Endwalker'') expansions. He was trying to complement Alphinaud [[DudeLooksLikeALady looking more manly than he used too]], so the tomboyish but still proudly female Alisaie does ''not'' [[BerserkButton take this well]].
107	---> '''Alisaie Leveilleur''': I... am ''not''... '''ALPHINAUD!'''
108	* Before the events of ''VideoGame/FireEmblemTheBindingBlade'', Raigh stole one of Hugh's spellbooks. Before the beginning of Hugh and Lugh's support, Hugh mistook Lugh for Raigh and grabbed him by the collar: to his credit, Hugh realizes his mistake and starts said conversation by apologizing to Lugh. When Lugh apologizes for Raigh's general bad behavior, Hugh waves it away and insists that he was the one at fault for being so violent towards a kid.
109	* ''VideoGame/HerStory'' suggests that the trigger for the murder was [[spoiler:Hannah posing as Eve and Simon falling for the deception, giving her another "unique" mirror to show his love]]. At least that's [[TitleDrop her story]].
110	[[/folder]]
111
112	[[folder:Web Animation]]
113	* ''WebAnimation/MangaSoprano'': [[https://youtu.be/Rlcff4gSZNI Mai]] called her sister Ai to gloat about stealing her husband Yuki, only to find out via videocall [[spoiler:that Yuki is dead; the man she bedded turned out to be his delinquent twin brother Koki, who robbed her of her wallet, passbook, and seal after sleeping with her.]]
114	[[/folder]]
115
116	[[folder:Webcomics]]
117	* ''Webcomic/CirqueRoyale'': While Fred and Will aren't identical twins -- they were born as [[spoiler:conjoined]] HalfIdenticalTwins and Will transitioned -- [[https://www.tumblr.com/cirqueduroyale/735989092681138176/episode-10-the-kings-monster-pt-19-rip-king Kingston makes this mistake]] in "The King's Monster," calling them by each other's names and pushing their BerserkButton. They both angrily yell at him for it, in part because the two of them are already fighting about the performance script and Kingston gave them both the same target for a short moment before they turned on each other again.
118	* In ''Webcomic/TheInexplicableAdventuresOfBob,'' when Fructose Riboflavin first encounters Galatea, he assumes she's her identical sister Molly, and takes great offense that she doesn't recognize him. In turn, Galatea is irritated when she realizes he's mistaken her for Molly.
119	-->'''Galatea''': "But you should know there's a significant difference twixt my sister and I. [[CuteMonsterGirl I understand how my claws work."]]
120	* A fraternal twin example occurs in ''Webcomic/WelcomeToRoom305''. Rumors spread about the campus that Yoongsung is a {{crossdresser}}. It turns out people were seeing his {{Half Identical Twin\|s}} sister Yoona.
121	[[/folder]]
122
123	[[folder:Western Animation]]
124	* ''WesternAnimation/HarryAndHisBucketFullOfDinosaurs'': In one episode, Harry mistakes a [[{{Snowlems}} sentient snowman]] named Mr. Snow for his twin brother, since naturally both brothers have the same last name.
125	* ''WesternAnimation/GravityFalls'': After his brother's disappearance, [[spoiler:Stan]] went shopping in town and was mistaken for him (the brothers are noticeably different-looking, but the townsfolk weren't very familiar with either). He [[SureLetsGoWithThat went along with it]], inspiring him to [[TwinSwitch assume his brother's life entirely]].
126	* ''WesternAnimation/TheGarfieldShow'': A running gag has people not being able to tell Jon Arbuckle's twin nieces/cousins once removed Drusilla and Minerva apart. Heck, sometimes the twins get ''themselves'' mixed up.
127	* ''WesternAnimation/TheLoudHouse'':
128	** Played with in "Training Day", when Lana initially thinks Snazzy the rabbit is Stella's rabbit Jazzy. They turn out to be brothers from the same litter, though it's unknown if there were any others in the litter.
129	** In "Fam Scam", when Cricket sees her classmate Lola's twin sister Lana for the first time, she believes that Lola changed her clothes.
130	** In "Double Trouble", when the Loud twins meet Scoots's twin sister Mopes (so-called because she rides a moped), they think she is Scoots in disguise.
131	* ''WesternAnimation/RazzberryJazzberryJam'': At the beginning of “A Bonnie Tale”, Buddy mistakes Bonita for her twin brother Woody (who the Jazzberries had been expecting, but who had to send Bonita in his stead due to being sick).
