Gender Misdirection happens when an unseen character is referred to by gender-neutral nouns and honorifics (Doctor, President, Judge), or also nouns generally associated with one specific gender, causing the viewers to assume the character is male when they are actually female or vice versa. TheReveal that they are the opposite sex is generally treated as a surprise by the other characters, and if the twist is done correctly by the writer the reader/viewer should have the same reaction.

This trope loses its subtlety in languages that have gendered definite and indefinite articles. The use of the character's name instead of pronouns is a major giveaway that this is the case. [[GenderBlenderName This is, however, also possible to subvert by using diminutives usually associated with one particular gender (Alex is usually a male short form, but it can also be for Alexandra. Sam can be a short form for Samantha).]]

See also SamusIsAGirl, which is the same but with a character who has appeared on screen prior to the reveal, and SheIsTheKing, where the character has a title associated with a specific gender, but is the opposite gender the title implies. Contrast with GenderNeutralWriting. CastAsAMask may also be used to obscure a character's real gender, especially if the character is not actually seen on screen.

[[folder:Anime & Manga]]
* In ''LightNovel/ScrappedPrincess'', Mauser is referenced throughout the series either by name only or as "Lord God Mauser". Mauser's name even sounds like it would belong to a male. In the end, however, not only is Mauser revealed to be a woman, [[spoiler: she looks like a twenty-something version of Pacifica!]]
* In ''Manga/{{Bleach}}'', the heroes talk about the rumored Kuukaku Shiba as a guy (not helped by the fact that the name sounds very masculine in Japanese) until they discover proof of the contrary and see that ''she'' is in fact a very busty woman.
* In ''Manga/HappyYarouWedding'', Todou refers to Chiharu, Kazuki's tutor, as being a "substitute mother" to Kazuki. Yuuhi assumes he's a woman because of this ambiguity, but he ends up being a man.
* In the ''Manga/OnePiece'' fandom, Dadan was speculated to be a man, but eventually proved to be a woman. [[BrawnHilda An ugly woman]] but still a woman.
* Alluka from ''Manga/HunterXHunter''. Turns out that the second youngest "brother" in the Zoldyck family is a girl (or possibly a male to female {{transsexual}}). Not important to the story, but it had fans in an uproar. Made more confusing by the fact that one of the actual brothers, Kalluto, is a case of DudeLooksLikeALady, so fans were already used to expecting a feminine looking figure to actually belong to a boy.
* In ''LightNovel/MaoyuuMaouYuusha'', Hero comes to the Demon world to search for the Maou (translated as "demonic ruler"), and is extremely surprised to discover that ''she'' is in fact a very polite, buxom redheaded woman. Though her title in Japanese is technically gender neutral she's assumed in story to be male until the reveal, and some translations refer to her as the Demon ''King'' to keep the ambiguity.
* In ''VisualNovel/SteinsGate'', alleged time traveler John Titor is given a male voice when his online chats are read aloud in the narration, which along with the name disguises that he's actually a female character, [[spoiler:Amane Suzuha]].
** Also used in regards to the true identity of FB, Moeka's contact and LivingEmotionalCrutch, since the distinctly feminine tone of FB's texts to her disguises that they're actually being sent by [[spoiler:Tennouji Yuugo/Mr. Braun]].
* ''LightNovel/ACertainMagicalIndex'' the leader of GREMLIN is only ever referred to as either One Eyed Odin or One Eyed Othinus, named after a male god from NorseMythology, which makes it quite surprising when she's revealed to actually be a 14 year old girl.
* With a name like [[Manga/GetBackers Clayman]], it's no surprise that the main characters are quite shocked to see that she's a woman instead.

[[folder:Film]]
* In ''Film/{{Ghostbusters}}'' Gozer is assumed to be a man but appears in the form of a woman.
-->"I thought Gozer was a man."
-->"It's an ancient Sumerian deity, it's whatever it wants to be."
* In ''Film/TheAvengers1998'', the head of the Ministry is a man codenamed "Mother", as in the series. To continue the joke, his deputy is a woman called "Father".
* ''Film/{{Hitch}}'' has characters repeatedly referring to Allegra Cole's "best friend," Maggie, who is a designer. Everyone assumes Maggie to be a female, but when Albert finally meets "her," Maggie's a man.
* ''Film/Cube2Hypercube'' has many people looking for "Alex Trusk," who is only known by name, as a hacker. [[spoiler: It turns out that "Alex" is Sasha, who has been in the hypercube with them the whole time. Also doubles as a BilingualBonus since "Sasha" is a common diminutive for people named Alexander/Alexandra in Slavic countries]]
* Neville's dog in ''Film/IAmLegend'' is referred to as "Sam" throughout until Neville yells out "Samantha" when she is injured and infected trying to protect him. The reveal makes the scene extra sad.
* ''Film/{{Them}}'' features Dr. Pat Medford, who the characters expect to be a male entomologist, presumably named Patrick, instead of the female entomologist named Patricia. ''Them!'' was [[FollowTheLeader such an influential film]] that a great many science fiction films of the era also had female scientist characters with male or androgynous names... sometimes even when there wasn't any actual misdirection!
* In ''Film/IndianaJonesAndTheLastCrusade'', Indy and Marcus know that "Dr. Schneider" will meet them in Venice, and expect a man, not the beautiful Dr. Elsa Schneider.

[[folder:Literature]]
* In ''[[Literature/TheBelgariad The Malloreon]]'', everyone just assumes Zandramas is male until Salmissra spills the beans.
* The Quarters series by TanyaHuff often refers to minor or background characters by their occupation "two guards," "a secretary" a few lines before the gendered pronoun is used. The reader then realizes that the guard or secretary to which s/he had unthinkingly assigned the "conventional" gender is, in fact, just the opposite.
* In ''Literature/TheLostSymbol'', Langstron assumes that the head of the CIA's Office of Security, Inoue Sato, is a man before meeting her.
* In ''Literature/{{Otherland}}'' by Tad Williams, Orlando Gardiner and Sam Fredericks only know each other through their online role-playing personas, which are both male. Later it is revealed that "Sam" is in fact a girl.

[[folder:Live-Action TV]]
* During the first episodes of ''Series/PrisonBreak'', we learn that Lincoln was framed for killing the Vice-President's brother. Behind this conspiracy, there's a mysterious unseen and unidentified woman, only heard and usually seen doing seemingly household chores, who seems resolute to expedite Lincoln's execution. Later it runs out that ''she'' is the Vice-President. %% The reference to her as the Vice-President is this trope, as the viewers would expect a man. %%
* During most of the first season of ''Series/{{Alias}}'', Sydney and SD-6 run up against an organization led by a mysterious character referred to as simply "The Man." In the season finale it is revealed that The Man was a woman... [[spoiler:Irina.]]
* In ''Series/{{Lost}}'', Danielle Rousseau abducts Sayid thinking he was one of those who had kidnapped her daughter. She questions him about her whereabout, but only refers to her as "Alex" and "child." The [[GenderNeutralWriting ambiguity of such nouns]] were conveyed onto the DVD set foreign subtitles that translate "child" as "son." In season two, we meet a girl who only later is revealed to be Alexandra, her long lost child.
* In ''Series/TheXFiles'' this was [[WhatCouldHaveBeen planned]] for Mulder's new MysteriousInformant Mr. X (after [[spoiler: Deep Throat is killed]]), an actress is even the one providing the silhouettes initially, but this was changed at the last minute.
* Done InUniverse on ''TheCommish'', where Tony's new NumberTwo is a female but his wife doesn't realize that until she meets her, because Tony always refers to her as "Syd."
* In the first ''Series/StargateSG1'' episode Captain Samantha Carter is intentionally referred to as Captain Sam Carter so that O'Neill can shoot his mouth off about having 'some new guy' added to his team as she walks in behind him.
* Similarly on ''Series/LasVegas'', famed Casino Host Samantha Marquez is referred to as "Sam," and thus assumed to be a man by Danny.
* In an early episode of ''Series/ThirtyRock'' Jack sets up Liz with a friend of his named Thomas, who turns out to be a female named Gretchen Thomas. Jack thought Liz was a lesbian.
* {{Averted}}: On the episode "All Mixed Up" of ''CougarTown'' they do a similar thing with Jennifer Aniston's character who repeatedly brings up "Gabriel" while discussing Jules' son. Then it turns out Gabriel was her dog.
* In one episode of ''Series/HowIMetYourMother'' Marshall and Barney keep on telling Ted stories about a wild coworker named Jenkins. Jenkins is purported to have done many things, like telling bawdy stories, drinking heavily, and participating in eating contests. Since the show is narrated from Ted's point of view, the scenes involving Jenkins show an enthusiastic, overweight, and middle-aged man (presumably what Ted imagines Jenkins to look like). Of course, later on, Jenkins is revealed to be a young woman, and when Ted replays the scenes in his head with the real Jenkins, they take on an entirely different tone.
* In the TV series ''Series/TheAvengers'', Steed's boss, codenamed "Mother" (or some variations on "grandma" in translations), is a man in a wheelchair.
* ''Series/MarriedWithChildren'': Al works at Gary's Shoes & Accessories For Today's Women. Al worked there for 20 years before finally meeting Gary and learning Gary is a woman.
* The mysterious BigBad of ''Series/{{Utopia}}'' is [[OnlyKnownByTheirNickname only known as Mr. Rabbit]]. [[spoiler: This is one of her many, ''many'' misdirections.]]
* ''Series/{{Alias}}'': "The Man," who is in charge of yet another private terrorist group/espionage agency, turns out to be Sidney's (heretofore presumed dead) mother.

[[folder:Videogames]]
* In ''VideoGame/MetalGearSolid'' we hear about Dr. Clark, who turned Gray Fox into the Cyborg Ninja. In ''VideoGame/MetalGearSolid4'' we discover that Dr. Clark is a woman, Para-Medic from ''VideoGame/MetalGearSolid3''. In this case it's one-half this trope (in universe, since the character who referred to her as man had never actually met her) one part RetCon since they decided to combine two different characters.
* Harold Berselius, the [[HotScientist Hot]]/MadScientist in ''VideoGame/TalesOfDestiny2'', is in fact a woman and chose "Harold" on purpose to surprise people.
* In ''Franchise/MassEffect'', you don't see "Jack", the deadly Subject Zero, until the end of the mission. You've heard a number of people in the nightmarish prison Purgatory refer to Jack in terror up until this point. When you release Subject Zero from the cryogenic cell the notorious criminal's been sealed in as a safety measure, most players were probably a little surprised to find that ''she's'' a small young woman in her twenties. Unless, of course, you [[TrailersAlwaysSpoil followed the trailers diligently]].
* In ''VideoGame/{{Tekken}} 6'', the character Leo seems to deliberately invoke this trope. (It's short for Eleonore/Eleonora)
* The true identity of the Imperator Librarius in ''Videogame/BlazBlue'' turns out to be a female, [[spoiler:Jun and Ragna's long-lost sister Saya]] a fact disguised by the masculine sounding title. Less so in the original Japanese where the title is the gender-neutral "Mikado."

* In the ''WesternAnimation/PhineasAndFerb'' episode "Oil On Candace", Dr. Doofenshmirtz is awaiting a visit from his old [[CardCarryingVillain evil science professor]], "the mighty [[NamesToRunAwayFromReallyFast Dr. Gevaarlijk]]!" No pronouns are used to refer to Gevaarlijk before she appears, and she turns out to be a diminutive older lady.
** Brazilians don't have a gender-neutral equivalent for "Professor". When the episode where Professor Poofenplotz was first mentioned was translated for Brazilian audiences, they used the masculine equivalent. Then the episode "Isabella and the Temple of Sap" reveals Professor Poofenplotz is a woman.
* ''WesternAnimation/BatmanTheAnimatedSeries'': Batman believed the terrorist known as "Red Claw" to be a man until they met.
* ''WesternAnimation/PolePosition'': The heroes once had to meet a T. D. Russel and were never told if Russel was a man or a woman. After getting rid of two men claiming to be Russel, they learn the real one is a woman.
* ''WesternAnimation/WhatsNewScoobyDoo'': The gang once went to an amusement park without knowing anything about its owners than their names (Chris and Terry) and their fame obtained by building the park's rides. The gang (mostly Shaggy) expected Chris and Terry to be men but it turns out they're girls.
