* ''Series/{{UFO}}''. The SHADO organization captures people who see real [=UFO=]s and has its medical department use a drug to erase their recent memories, thus preventing the public from learning about UFO attacks.

* The ''Wiki/SCPFoundation'': "Class A Amnestic administered to all survivors."

* A typically dark example from ''TabletopGame/Warhammer40000''. Since admitting the existence of an elite army of {{demon slay|ing}}ers would be admitting that there are such things as demons, the Imperium treats the Grey Knights as a state secret enforced by specially-trained psykers. Other {{space marine}}s who fight alongside them go through a lengthy memory-scrubbing afterwards, while Imperial Guardsmen who distinguish themselves are subjected to a hasty process that is both painful and often fatal. [[HeKnowsTooMuch Everyone else is just executed]]. An especially notable example was after the first war for Armageddon; after the invasion was driven off, the entire population of the planet was sterilized and worked to death in concentration camps.

* In ''Film/MenInBlackII'' they even use a gigantic neuralizer hidden in the Statue of Liberty, capable of wiping the memories of all New York City.

* In the ''Literature/HarryPotter'' stories, if a wizard lost control and accidentally used his powers (or some other event that would endanger the safety of the wizarding world), the Ministry of Magic would dispatch a special group called [[SelectiveObliviousness Obliviators]] to see to it that people's memories of the event were altered.

* In the Literature/ArtemisFowl series, the fairies can wipe the memories of any humans who learn about them, as they do to Artemis and his friends at the end of the third book (they all get better). There are even two different techniques they use. One is a block wipe, which just takes out a huge chunk of memory, but the longer the interval of time taken out, the greater chance there is for permanent mental damage. The other is a fine-tuned wipe which removes specific events, people, etc., but takes a lot longer than a block wipe.

* [[{{WesternAnimation/GravityFalls}} Gravity Falls]] has [[spoiler: The Society of the Blind Eye, a cult dedicated to erasing traumatic memories the townsfolk have of the various bizarre creatures that live in the town.]]

Compare TheMenInBlack, CleanupCrew. Contrast the more brutal KilledToUpholdTheMasquerade.

* ''Anime/DigimonSavers'' has DATS, an organization responsible for keeping Digimon a secret from normal people. Memory-wiping via a neutralizer-type device is how they deal with any potential witnesses.

* In ''Fanfic/TheRivalPrefectsTrilogy'', Malcolm and Basil had to use memory charms to make the rest of Hogwarts forget that Thomas ever existed.

* ''Fanfic/ThisBites'' has the "Cleaners", a subdivision within the New World Masons at the behest of Cross, who prefers those who find out about their group get memories erased rather than killing them. Said Cleaners are composed of [[spoiler: Vice-Admiral Tsuru, Miss Goldenweek, Jango, Kalifa and CanonForeigner Popora]].

* ''ComicBook/MarvelAdventures: Super Heroes'': ComicBook/DoctorStrange rapid-fires a memory wiping spell on museum visitors who'd just seen him battle a fire-breathing squirrel [[spoiler: who was secretly [[DimensionLord Dormammu]] in squirrel form)]].

--> '''Strange''' (to three {{Muggle}}s): Leave and forget. Leave and forget. Leave and forget.

* In ''[[Literature/NightWatch Sixth Watch]]'', the characters wonder how extremely important information about the origins and true nature of the [[DifferentlyPoweredIndividual Others]] could have been hidden or forgotten. [[spoiler:It was the Great Others themselves, who have wiped their own and others' memories in order to keep that knowledge from interfering with their plans for a perfect world. One, a witch, has managed to retain the memories by imparting them onto an artifact. Her memories were restored as soon as she touched it]].

* Lacuna Inc, from ''Film/EternalSunshineOfTheSpotlessMind'' are a non-MIB version, removing memories of bad relationships. They would even set up in the client's home so they would wake up without any idea that something had happened.

* In a lesser form, in ''Manga/TheWorldGodOnlyKnows'' the demons of new hell [[LaserGuidedAmnesia "restart"]] (later, they simply changed them) the memories of the girls who's holes got closed.

* In the ''Disney/LiloAndStitch''[=/=]''Franchise/StarTrek'' crossover ''[[FanFic/StarlightSeries Starlight]]'', this task is performed by [[spoiler:Dulmer and Lucsly from Temporal Investigations, although in this case it's to rectify the timeline.]]

* A typically dark example from ''TabletopGame/{{Warhammer 40000}}''. Since admitting the existence of an elite army of {{demon slayer}}s would be admitting that there are such things as demons, the Imperium treats the Literature/GreyKnights as a state secret enforced by specially-trained psykers. Other {{space marine}}s who fight alongside them go through a lengthy memory-scrubbing afterwards, while Imperial Guardsmen who distinguish themselves are subjected to a hasty process that is both painful and often fatal.

* In ''SamAndMax'' season 2, Agent Superball will emphatically deny time travel, even though the machine is parked right in the room. Any continued discussion of it will provoke him to employ his hypnotic, memory wiping powers. This is used for a puzzle later.

* The [[http://en.wikipedia.org/wiki/List_of_magical_beings_in_Charmed#Cleaners Cleaners]] in ''Series/{{Charmed}}''. In order to keep magic a secret from humanity they remove the memories of anyone who sees a supernatural event. They're capable of {{Retcon}}ning reality to the extent of undoing a person's birth, and yet only appeared in one episode relatively late in the show. [[FridgeLogic So where were they all those other times the masquerade was threatened?]]
