[[ExactlyWhatItSaysOnTheTin The post-mortem examination of an extra-terrestrial being]], oftentimes winding up on video tape.

Whenever any aliens find their way to Earth, you can be pretty sure that human governments and scientists will want to study their [[BizarreAlienBiology Bizarre Alien Biologies]]. Naturally, if the alien creature is still alive, X-Ray and CT Scanning technology can, at least, allow for a sizable chunk of that information to be gained "humanely." However, if the alien subject is deceased, then doctors are going to be setting up E.T. for an up close and personal look of his insides on the nearest operating table.

This trope is one of TheNewestOnesInTheBook, with its origins dating back to [[TheNineties the mid-1990's]] when UFO [[ConspiracyTheorist Conspiracy Theorists]] began speculating that one such autopsy was performed in the wake of [[RoswellThatEndsWell The Roswell Incident]]. The fact that the fifty-year anniversary of that event was approaching at the time, which led to increased coverage of the story in the media, surely helped spread the rumor, as did a video recording purporting to be the alleged autopsy in question, which is now largely regarded as a hoax. Regardless, the concept (including, on occasion, the aforementioned part about it usually being a hoax) has gone on to become as much a staple in SpeculativeFiction and [[AlienTropes alien lore]] as AliensStealCattle and AnalProbing are.

Related to TheyWouldCutYouUp, which would be more focused on the fears an alien or unique character would have about being subjected to human study and vivisection.

!Examples

[[folder: Anime And Manga ]]

* In one episode of ''LightNovel/{{Durarara}}'', we see [[HeadlessHorseman Celty]] watching a documentary on one of these in the background while Shinra speaks on the phone. Celty, as it turns out, [[WhyDidItHaveToBeSnakes is terrified of aliens]]. This despite the fact that she's a Celtic fairy (who might also be a {{Valkyrie}}) and may be [[CompleteImmortality completely unkillable]].
* In an early episode of ''DaaDaaDaa'', Miyu tries to call her mother (working overseas for UsefulNotes/{{NASA}}) for advice on what to do with the suddenly-arrived alien baby, but is discouraged when her mother starts enthusiastically (and [[{{Squick}} graphically)]] describing the alien autopsy video she's watching.

[[/folder]]

[[folder: Comics ]]

* Referenced in the ''Bec & Kawl'' story arc "Attack Of The Cones" from ''ComicBook/TwoThousandAD''. TheGreys who have [[AlienAbduction abducted]] Pierre and suspect him of being a soldier of some sort contemplate killing him with the dialogue at the top of this page serving as their rationale.

[[/folder]]

[[folder: Film ]]

* Though not an actual autopsy, ''Film/IndependenceDay'' sees Dr. Okun and his colleagues at {{Area 51}} stripping off the [[OrganicTechnology bio-engineered suits]] of an unconscious alien pilot in preparation of one. [[spoiler: The alien wakes up halfway through and has both PsychicPowers and control of the armor's tentacles]]. Three others are said to have been studied in such a manner after the Roswell crash; their remains are kept on display.
* Professor Kessler performs one on a dead Martian in ''MarsAttacks!''
* In ''Film/MenInBlack'', the coroner, Laurel, ends up performing these inadvertently on two non-human corpses. It's suggested that she is one of the [=MIB=]'s most frequently [[LaserGuidedAmnesia neuralized]] individuals for this very reason.
* MNU's laboratories from ''Film/{{District 9}}'' sure have the remains of ''a lot'' of dead Prawns lying around, although unlike other examples of this trope, they were likely all killed by MNU. If they're not lying dead and mutilated on an operating table, they're probably ''suspended on a meathook''. [[spoiler:In Wikus's case, MNU scientists opt to try and perform [[TheyWouldCutYouUp a vivisection]].]]
* The 2006 British Comedy ''A'''lie'''n Autopsy'' centers around the creation of the original autopsy video that serves as the TropeMaker. The promotion of this film is what led the creator of the original autopsy video to come clean about the true authenticity of his video.
* In ''Film/{{Paul}}'', the BigBad wanting to do this to Paul is what sets off the plot.

[[/folder]]

[[folder: Literature ]]
* ''Passage of Earth'', a short story by Michael Swanwick. A coroner is given a large alien worm-like creature to dissect after a spaceship crashlands on Earth, killing its crew of hundreds of worms. [[spoiler:From his examination he speculates that the alien, which is blind, examines its surrounding mostly via taste. Halfway through the autopsy he has an irresistable compulsion to eat part of the worm whereupon it takes him over; he beats to death his ex-wife who brought him the corpse and drives out into the desert while reliving this and other unpleasant memories from his life. Belatedly he realises that he's the one being autopsied - out in the desert was another spaceship whose crew consumed him, but this all happened years before and a worm is sampling his memories as it digests him over the eons between star systems.]]

[[folder: Live Action TV ]]

* The TropeMaker, of course, is the footage of the alleged AlienAutopsy that occurred after the fateful event in [[RoswellThatEndsWell Roswell, New Mexico]] which eventually became the {{FOX}} Network's 1995 TV special ''Alien Autopsy: Fact Or Fiction''. The special gained a lot of media attention as well as a lot of criticism for not showing many of the autopsy's significant findings with a lot of the footage appearing extremely pixelated and/or with the examiner blocking the camera's view (or simply cutting away just as something interesting is happening). Over a decade later, the person who originally presented the footage admitted that video wasn't entirely authentic but a re-creation of ''another'' alien autopsy video that he claimed to have once seen with "a few frames" from that "original" video appearing in the one that was showcased in the TV special. As a result, most people tend take this admission as a sign that it was ''all'' a hoax.
* ''Series/TheXFiles''
** [[PlayingWithATrope Played With]] this one as well as made a ShoutOut to, and a TakeThat against, the TropeMaker in the episode "[[Recap/TheXFilesS03E20JoseChungsFromOuterSpace Jose Chung's 'From Outer Space'.]]" According to AgentScully's [[RashomonStyle interpretation of events]], an autopsy which she performed on an alien and allowed to be video taped became commercially released as "Dead Alien: Truth Or Humbug." Embarrassed by it, Scully complains that the video ignores several of her findings, chief among them being that the dead alien was revealed to be a ManInARubberSuit.
** Another episode saw Mulder buy pirated alien autopsy footage. Scully comments that [[BitingTheHandHumor it looks hokier than the FOX autopsy]]. Only this time the footage turns out to be real.
** The MythArc episode "[[Recap/TheXFilesS04E24Gethsemane Gethsemane]]" sees Mulder observe an autopsy on something which everyone involved believes to be an alien. [[spoiler: However, an employee of the Department of Defense, Michael Kritschgau, suggests to Mulder that it is not a real alien but only what [[PowersThatBe "they"]] want Mulder to see.]]
* On ''Series/NewsRadio'', Joe, Beth, and Matthew act out a fake alien autopsy (with Matthew as the alien) in front of a 24-hour webcam for the radio's website.
* In the [[Recap/StargateSG1S1E1ChildrenOfTheGods pilot]] of ''Series/StargateSG1'', the military has an autopsy performed on a Jaffa killed during the initial attack on the base.
* One sketch from TheWhitestKidsUKnow sees a team of doctors at {{Area 51}} beginning to perform one such autopsy on an alien corpse recovered from [[RoswellThatEndsWell Roswell]]. [[spoiler: Only it turns out to be a pinata shaped like a [[TheGreys Grey Alien]] and filled with Reeses Pieces candies.]]
* Subverted on ''{{Tracker}}'', where it appears that the government scientists are going to start dissecting Cole-but the light shining on him warms him enough to wake him up and allow him to hyperspeed out of there.
* In the ''Series/{{Farscape}}'' episode, "[[Recap/FarscapeS01E16AHumanReaction A Human Reaction]]", the crew of Moya lands on Earth [[spoiler: but not really]] and Rygel is dissected.
* Subverted in ''Series/{{CSI}}'', with the "alien" Doc Robbins examined was actually a human with a medical condition that made him look enough like a Grey to get him a job at a UFO-themed wedding chapel.

[[/folder]]

[[folder: Magazines ]]

* ''Magazine/NintendoPower'''s walkthrough guide for ''BodyHarvest'' for the N64 includes one level where the PlayerCharacter has to rescue a captured [[TheGreys Grey]] from Roswell. One picture caption for the level humorously tries to guilt trip readers into sympathizing with the alien and make them feel bad "for having laughed at that alien autopsy video".

[[folder: Pinball ]]

* This is the focus of the Martian Autopsy mode of ''Pinball/RevengeFromMars''.
--> "That's not a spleen, that's my wife!"

[[/folder]]

[[folder: Theater ]]

* One of the highlights of the play ''The Aliens are Coming! The Aliens are Coming!'' is an alien autopsy.

[[/folder]]

[[folder: Toys ]]

* Mattel's 1980s MadScientist toyline included the memorable [[http://www.retrojunk.com/content/article/8152/index/ Dissect An Alien]] kit, a sort of 3D puzzle complete with scalpel and green glow-in-the-dark blood.

[[folder: Video Games ]]

* In ''VideoGame/{{X-COM}}'', the player's scientists can perform these. Aside from giving you points when it's finished, it sometimes gives you information about what that particular alien is vulnerable to. However, expect lots of inaccuracies (for example, Reapers are said to have flammable hides but incendiary damage is really buggy in the game). In [[VideoGame/XCOMEnemyUnknown the 2012 reboot]] the autopsies instead give you things such as new technologies.
* In ''Videogame/XCOMEnemyUnknown'', you can also perform autopsies on aliens, which gives you not only information on enemy abilities, but also access to technology or upgrades that can be used by harvesting components of alien corpses. In the ''Enemy Within'' expansion, this also gives you access to gene mod upgrades for your soldiers as well.
* The ''UFOAfterblank'' series has this too. Notable in that unlike X-COM's aliens, transgenants are pure NauseaFuel even ''without'' being cut up. On the other hand, the autopsy reports are ''always'' correct about what the transgenant is vulnerable to.
* The Area 51 stage of ''VideoGame/PerfectDark'' has a level which involves rescuing an alien from vivisection, and another (bonus) level involves sabotaging the autopsy of an already dead alien.
* Touring around the Area 51 compound in the original ''VideoGame/TonyHawksProSkater'' will reveal a number of alien artifacts surrounding a skating bowl. Amongst the captured UFO and military paraphernalia is an Alien predictably undergoing an autopsy on an operating table.
* In ''VideoGame/DeadSpace3'', ''you'' get to do this. In Mission 12, the player needs to climb ''into'' a frozen Nexus Necromorph in order to get data from its nervous system.

[[/folder]]

[[folder: Web Original ]]

* One SomethingAwful front page column from an ongoing series from US Vice President Joe Biden writing about ''Series/TheXFiles'' mentions him meeting a fellow fan of the show who gives him a VHS copy of the hoax alien autopsy video, which Biden believes to be authentic.
--> '''Joe Biden:''' I asked Barack about the video and he says it was an old fake, but I'm not so sure. That was a dead alien being autopsied, and I saw the evidence with my own eyes.

[[/folder]]

[[folder: Western Animation ]]

* In the ''WesternAnimation/{{Futurama}}'' episode "[[Recap/FuturamaS3E19RoswellThatEndsWell Roswell That Ends Well]]", Dr. Zoidberg [[HistoricalInJoke turns out to be the Roswell alien that got cut open]]. However, he's still alive and conscious and does things, like re-eating the deviled egg they take out of his stomach and making remarks like, "Take, [[BizarreAlienBiology I've got four of them]]" when when his heart is removed.
--> "Don't touch that! I need that to speak!" ''(Surgeon saws even faster)''
* ''WesternAnimation/TheSimpsons'' episode "Worst Episode Ever" sees Bart and Milhouse uncover a secret room in Comic Book Guy's shop which houses a secret stash of bootleg videos and other illegal video clips. Among the video titles mentioned are "Alien Autopsy" and "Illegal Alien Autopsy".
* ''WesternAnimation/AmericanDad'' Roger is cut up by an Alien Hunter, but thanks to his [[BizarreAlienBiology species's ability to stay alive]] as long as their head is intact, Roger lives.
* One episode of ''WesternAnimation/AllGrownUp'' has Dil steal a tape of what is supposed to be an alien autopsy, planning to play at a viewing party he is hosting, but the tape gets destroyed before anything is shown and they have to film a fake one.
