->''"In the mid 1980s, I was asked to compile a comic book detailing the murky history of the CIA. What I learned during the frankly horrifying research was that, yes: there is a conspiracy. In fact, there are a great number of conspiracies, all tripping each other up."''
-->-- '''Creator/AlanMoore'''

Everything you've heard is true: TheIlluminati rule the world, the moon landings were faked, [[UsefulNotes/JohnFKennedy JFK]] was assassinated by a bunch of gray aliens, and you surely don't think the Cuban Missile Crisis was about Cuban Missiles, do you?

Yes, that's right: In this setting, every conspiracy theory you've ever heard of is true. And some you haven't. A closely related subtrope to FantasyKitchenSink, but conspiracy-minded, rather than fantastic; like its parent, there is a certain tendency towards self-contradiction, but given the source of the trope (paranoid conspiracy theories), not that surprising, and sometimes not even that damaging.

Following things are a must-have for any Conspiracy Kitchen Sink worth its salt (for required ''tropes'', see TheIndexIsWatchingYou):

* A SecretWar between TheIlluminati, UsefulNotes/TheKnightsTemplar, UsefulNotes/TheHashshashin, the [[CouncilOfVampires Vampire Courts]], TheFairFolk, Freemasons, [[ThoseWackyNazis Nazi]] holdouts (the [[{{Ghostapo}} Thule Society]], [[ArgentinaIsNaziland Argentinian Nazis]]), the {{Girl Scouts|AreEvil}}, Opus Dei, TheMafia, [[SinisterSpyAgency CIA]] and [[UsefulNotes/MoscowCentre KGB]], [[AIIsACrapshoot Rogue AIs]], [[CosmicHorrorStory Lovecraftian]] and [[HollywoodSatanism Satanic]] {{cult}}s, UsefulNotes/ThePentagon, TheMenInBlack, Bilderberg Group, Majestic-12, TheGreys, and [[ReptilianConspiracy the Reptilians]]. Yes, all at once in one merry free-for-all that no {{Gullible Lemming|s}} ever notices.
* {{Precursors}} of any origin ([[AncientAstronauts extraterrestrial]] or {{ultraterrestrial|s}}) and disposition ({{benevolent|Precursors}}, {{abusive|Precursors}}, and/or simply {{neglectful|Precursors}}).
* Prominent involvement of {{Area 51}}, TheBermudaTriangle, MysteriousAntarctica, HollowEarth, and {{Atlantis}}, as well as the respective headquarters of the factions listed above. And [[BigApplesauce New York]].
* Nonchalant [[TheReveal revelations]] of the ''real'' allegiances and agendas of UsefulNotes/JesusChrist, Creator/LeonardoDaVinci, UsefulNotes/JackTheRipper, UsefulNotes/NikolaTesla, UsefulNotes/{{Rasputin|TheMadMonk}}, UsefulNotes/AdolfHitler, [[ArsonMurderAndJaywalking and]] Music/ElvisPresley.
* The sinister purpose of {{Ley Line}}s, ThePyramids, the HolyGrail, the PhilosophersStone, NumbersStations, [[WhatTheHeckIsAnAglet aglets]], and any number of other {{Public Domain Artifact}}s.
* The Truth behind the [[PhlebotinumKilledTheDinosaurs K–T extinction]], TheTunguskaEvent, RoswellIncident, SpontaneousHumanCombustion, Operation Paperclip, Project MKULTRA, Monarch MindControl program, [[WhoShotJFK Kennedy]] and Palme assassinations, CropCircles, the {{moon landing|Hoax}}s, the disappearance of the Roanoke Colony, the {{Lost Roman Legion}}s, the [[SubliminalSeduction 25th frame]], the [[ScandalGate Watergate scandal]], the first UsefulNotes/GulfWar (well, the ''real'' truth, anyway), TheEndOfTheWorldAsWeKnowIt as predicted by the {{Mayan|Doomsday}}s / UsefulNotes/{{Nostradamus}} / [[Literature/BookOfRevelation John of Patmos]], the EyeOfProvidence on [[CurrencyConspiracy the dollar bill]] and any number of other StockUnsolvedMysteries you can think of.

Compare CrossoverCosmology, the mythological version of this trope. Very often overlaps with WorldOfMysteries.

Occasionally leads to a GambitPileup, but not nearly as often as it should. Naturally, in all of these conspiracies, there are NoDelaysForTheWicked.

This trope covers {{settings}} and entire series/works. For the characters who ''believe'' they live in a Conspiracy Kitchen Sink, see ConspiracyTheorist.

----
!!Examples:
[[foldercontrol]]

[[folder:Anime and Manga]]
* ''Manga/BillyBat'': The manga is a historical fiction series in which a cartoon bat and the artists that become obsessed with it become entangled in several strange historical events and conspiracy theories. Among the events that happen in the series, [[spoiler:the moon landing was faked in 1961 and Lee Harvey Oswald was the fall guy, not the actual killer of JFK]].
* ''Manga/{{Dandadan}}'': All urban legends are true, whether they be ghost stories or alien conspiracy theories. Ironically, the two main characters start out with one believing in ghosts and the other in aliens, but refusing to believe the other one was true. They quickly find out how wrong they were.
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/BlackDynamite'': Discussed. [[TheIlluminati Illuminati]] leader The Man confirms that ''all'' the different rumors about shadowy cabals controlling world events are true, to which Black Dynamite simply replies, "I knew it."
* A lot of Creator/GrantMorrison's other work, features loads and loads of conspiracies. ''Comicbook/TheInvisibles'' deserves special mention though, since it takes place in a world where pretty much every single piece of conspiracy literature scrawled out in the last 60 years was all true. Simultaneously.
* The main protagonist of ''Hunter-killer'' (written by Creator/MarkWaid) has been home-schooled, and what he's been taught (as far as recent history is concerned) is all conspiracy theories. [[spoiler:And not surprisingly, all he's been taught is true, except the part about the week having six days.]] One major turning point, as it turns out, was indeed the Cuban missile crisis.
* In Comicbook/TheQuestion's [[ADayInTheLimelight spotlight issue]] of the ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'' tie-in comic, he spends a week solving every major conspiracy in western civilization's history. Stuff like "Jack the Ripper was cloned from the Chupacabras that landed in Area 51". It turns out a lot of it was faked, but that's the kind of stuff he makes a living investigating.
* ComicBook/{{SHIELD}} dips its toes into this. For starters, both it and HYDRA are a lot older than the governments they currently serve [[spoiler: as in, back to Egypt. And SHIELD has had Tesla and da Vinci amongst its ranks]]. There's also a throwaway line about how the Skrulls (shapeshifing reptilians, by the way) were involved with JFK's death.
* DC Comics did release two books, ''The Big Book of Conspiracies'' and ''The Big Book of the Unexplained'', and yes, not only did all of the conspiracies get inextricably jumbled together through references, but the two ''books'' managed to get intertwined as well.
* A particularly hilarious one appears in ''{{ComicBook/Hellblazer}}'': John explains to an increasingly terrified journalist that the British royal family are in fact reptiles born of matings between humans and snake-gods, in service to TheGreys, Princess Diana was killed so the public wouldn't find out about the BodyHorror needed to make her a breeder for reptile babies, and JFK arranged to commit suicide because he woke up to see his wife having sex with one of the snake-men and showing every sign of enjoyment. As John goes to the bathroom before beginning part 2, a gunshot is heard, and blood flows from a stall, scaring the journalist witless. [[spoiler:John was asked to get the journalist away from the palace before he could uncover a much more mundane drugs and prostitution ring, which he did by baiting the guy with high-grade BS and faking his execution.]]
* The ComicBook/{{Hellboy}} and especially ComicBook/{{BPRD}} comics are a combination of this and FantasyKitchenSink / AllMythsAreTrue, with [[OurVampiresAreDifferent vampires]], [[OurGhostsAreDifferent ghosts]], HumanoidAliens, {{Ghostapo}} and StupidJetpackHitler in [[ArgentinaIsNaziland South America]], TheFairFolk, AdvancedAncientHumans, the HollowWorld, SovietSuperscience, {{EldritchAbomination}}s, AngelsDevilsAndSquid all being real and covered up by the [[TheMenInBlack BPRD]].
* In a world where [[ClapYourHandsIfYouBelieve collective belief warps reality]], conspiracy theories in ''ComicBook/TheDepartmentOfTruth'' manifest as real-life monsters, selective memories, and other anomalous activity, things that only grown more and more dangerous the more sense they make to people. One of the Department of Truth's jobs is to decentralize conspiracies so that not too many people can latch onto the same idea. Oswald gives an example of various inane theories -- citing theories like Obama being from Kenya, that 9/11 was an inside job, and everything [=QAnon=] ever says -- and asks Cole to put them all together. Cole is able to weave a linear, ongoing narrative based around these facts where the world is being controlled by a globalist Shadow Government, Obama is the Antichrist and the War on Terror was all a plot to destroy America, a "big picture" that the Department is trying to prevent.
[[/folder]]

[[folder:Film -- Live-Action]]
* ''Film/AngryVideoGameNerdTheMovie'': Cooper believes in, among other things, the existence of the ''[[VideoGame/ETTheExtraTerrestrial Eee Tee]]'' dumping site, Area 51, that a UFO crashed in Roswell, and an omnipotent being named "Death Mwauthzyx" that can destroy reality if ever released from Mount Fuji. [[spoiler:Turns out, not only are these things true, but Music/TupacShakur, Music/ElvisPresley, and Music/MichaelJackson are all still alive and kicking in Area 51. Also, the moon landing was filmed.]]
* ''Film/CaptainAmerica1990'': The [[BigBad Red Skull]], who went underground after UsefulNotes/WorldWarII, is revealed to now be the head of a NebulousEvilOrganization which basically secretly runs the world, and was responsible for the assassinations of both the Kennedys and Martin Luther King, among other dastardly acts.
* ''Franchise/IndianaJones'': Most {{Public Domain Artifact}}s exist and do indeed have magic powers. Some of them even have {{Ancient Tradition}}s protecting them throughout the ages. And Indy's friends in the government take the things he finds to a military base out in the American Southwest. A very... ''crowded'' military base...
* ''Franchise/MarvelCinematicUniverse'': ComicBook/{{SHIELD}} are the TheMenInBlack hiding weird phenomena and creatures from the general public (particularly in [[Series/AgentsOfShield the television]] [[Series/AgentCarter spinoffs]]), even once the events of the movies (particularly [[Film/TheAvengers2012 an alien horde attacking New York City]]) turn it into TheUnmasquedWorld. And ''Film/CaptainAmericaTheWinterSoldier'' reveals [[spoiler:hidden within the agency is HYDRA, [[ANaziByAnyOtherName an offshoot of the Nazi army]] which managed to stay in the shadows for 70 years while orchestrating every war, evil government, and such.]]
* ''Film/Hellboy2004'' and [[Film/HellboyIITheGoldenArmy its sequel]]. The BPRD are clearly TheMenInBlack, and started out as a military attaché to a squad handling Hitler's occult plans.
* ''Film/IronSkyTheComingRace'' features a race of Precursors who created humanity and are also reptilian shapeshifting aliens who live in the HollowEarth in the mythical city of Agartha, where the HolyGrail is the main source of power. Dinosaurs also still live inside the Hollow Earth. Also, many historical figures (including Caligula, Margaret Thatcher, Osama bin Laden and... Mark Zuckerberg) are members of said reptilian race.
* ''Film/TheMatrixReloaded''. The Oracle tells Neo that the Matrix is full of programs controlling its individual elements, which are the source of myths and conspiracy theories about ghosts, angels, vampires, werewolves, aliens, and the like.
-->'''Oracle:''' The ones doing their job, doing what they were meant to do, are invisible. You'd never even know they were here. But the other ones, well, we hear about them all the time.\\
'''Neo:''' I've never heard of them.\\
'''Oracle:''' Oh, of course you have. Every time you've heard someone say they saw a ghost, or an angel. Every story you've ever heard about [[OurVampiresAreDifferent vampires]], [[OurWerewolvesAreDifferent werewolves]], or aliens, is the system assimilating some program that's doing something they're not supposed to be doing.
* ''Film/MenInBlack'' is a peculiar version of this -- every conspiracy theory you've ever heard is on to something big, but the truth behind all of them is the same, in this case aliens.
** One example is a small ball that seems to be similar to rubber except that it gains energy with each bounce, making it incredibly destructive. Apparently it caused a massive New York blackout. The alien diplomat who did it [[ItAmusedMe thought it was funny as hell]].
** Elvis' death? [[ElvisHasLeftThePlanet He was an alien who just went home]].
** J's theory about that one grade school teacher of his being an alien, though? Spot on, except that he got the wrong planet.
* Parodied in ''Film/UndercoverBrother'', as this spy comedy centers on a mysterious Caucasian BigBad who plans on subliminally ruining the image of the black community, and once the protagonist joins the organization that fights against The Man's efforts, he learns that all the anti-black conspiracies are true, but it's for funny/mundane matters such as "The [[UsefulNotes/NationalBasketballAssociation NBA]] really did institute the three-point shot to give white boys a chance" and "The entertainment industry really is out to get Creator/SpikeLee" because even Music/{{Cher}} won an Oscar, but when it gets to a more serious topic:
-->'''Undercover Brother:''' And [[Creator/OJSimpson O.J.]] ''really didn't do it.''\\
''[[[{{Beat}} awkward silence]]]''\\
'''Chief:''' We... we ain't got time for this!
* {{Parodied|Trope}} in ''Film/{{Zoolander}}''. [[HistoricalRapSheet Thousands of historical events]] can be traced back to [[MilkmanConspiracy elements within the fashion industry]].
[[/folder]]

[[folder:Literature]]
* James Ellroy's ''American Tabloid'' answers the question "Who killed JFK?", with a pretty resounding "Everybody". (If you want more specificity: [[spoiler:the assassination was bankrolled half by reactionary billionaire Howard Hughes and half by various Mafia bosses, the shooters were CIA contractors borrowed from one of the Company's many anti-Castro black ops, and J. Edgar Hoover personally directed the cover-up in the hours after the shooting]].)
* The world of ''Literature/ConstanceVerity'' has so many secret societies -- both [[NebulousEvilOrganisation evil]] and [[BenevolentConspiracy benign]] -- that it's a wonder that they aren't all busy going to war with each other instead of Constance. And that's not even going into Area51, mind-controlling fungus, androids, the Loch Ness Monster (which Connie had to save four times), The Great Engine that regulates the universe, supervillains, etc.
* The ''Literature/{{Illuminatus}}'' trilogy of novels by Robert Shea and Robert Anton Wilson is arguably the UrExample.
** [[spoiler:FNORD]]
** Why did someone put in a spoiler block with nothing in it?
** That's what they WANT you to think.
* ''1963'' had [[WhoShotJFK several conflicting theories on the JFK murder]], involving everything from aliens to the Illuminati to mind-controlling government officials.
* Umberto Eco's ''Literature/FoucaultsPendulum'' has the main characters invent their own synarchic plot (for fun) to explain all of the various conspiracy theories in the world. You can guess what happens next.
* Pretty much everything written by Creator/ThomasPynchon ''runs'' on this trope, ''especially'' ''Literature/GravitysRainbow''.
* In ''Conspiracies'', Literature/RepairmanJack attends a ConspiracyTheorist '''convention'''. Subverted in that [[spoiler: there really is a conspiracy happening behind the scenes... but it's against Jack himself, not anything the convention's attendees dreamed up.]]
* ''Literature/IClaudius'' is a hodgepodge of pretty much every half-baked conspiracy theory about the time of the Julio-Claudian Emperors, both then and since.
* The world of ''Literature/GoodOmens'' ends up turning into something like this. Thanks to Adam Young's growing RealityWarper powers, all the crackpot theories he reads about in Anathema's New Age magazines (like Tibetan tunnels, alien visitations, Atlantis, and the hollow Earth) [[RealityBleed start becoming true]]. [[PlayedForLaughs And it's absolutely hilarious.]]
* Anything written by Creator/DanBrown. The Robert Langdon books have had a habit of subverting this trope, however. While conspiracy theories are often thrown around by the characters, there usually ends up being a logical, or at least somewhat realistic explanation for everything. [[spoiler: In fact, {{Conspiracy Theorist}}s have ended up being the villain more often than not because they believe that nothing is true and everything in permitted.]]
* Website/TheOnion published an article about the JFK assassination that made use of this trope. "Kennedy Slain By CIA, Mafia, Castro, LBJ, Teamsters, Freemasons: President Shot 129 Times From 43 Different Angles". [[spoiler:And then every single shooter is gunned down by Jack Ruby.]]
* This is the entire purpose of ''Literature/MrBlank'' and its sequel ''Literature/GetBlank'', a detective story in which the hero works for literally every conspiracy there is, so when someone tries to murder him, there's no shortage of suspects. One of his most reliable tactics is playing off one conspiracy against another, such as pitting the Little Green Men against the Assassins and the Russian Mob in order to rescue his girlfriend.
* ''Literature/ReynardTheFox'': The notorious KarmicTrickster Reynard thinks up a conspiracy against the royal court and accuses everybody who tried to arrest him of being accomplices in the crime. Nobody questions his tale that rather conveniently gets rid of everybody who stood in his way.
* In ''Literature/StielaugeDerUrkrebs'', at least the Welteislehre and Atlantis are real. The author even provides a list of books about both topics at the end of the book, but none about paleontology, the main inspiration for the book.
* ''Literature/Area51'': The series manages to involve ''tons'' of popular conspiracy theories within its mythos (the author claims most are true), starting of course with Area 51. Yes, there is a secret base on the site, and the US government (or part of it anyway) is hiding alien craft they've been flying since the late '40s there. Also, they're behind alien abductions and crop circles (as disinformation confusing people). We later also learn most of what's believed about human history was wrong. The craft are from an alien species who colonized Earth millennia ago, and ruled ancient humans on {{Atlantis}}. Since it was destroyed, two different factions have been fighting each other behind the scenes, and numerous mythical figures were aliens in disguise or just influenced by them. Also, lots of mythical artifacts were real, but alien technology. There have also been many human (or part-human) stooges serving these aliens secretly, with them having infiltrated many world governments. Oh, and one faction was the force behind the Nazis. Plus, biggest of all: [[spoiler:they created humans to begin with.]]
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/AgentsOfSHIELD'': [[spoiler:HYDRA is revealed to be descended from a long, ''long'' line of one single conspiracy centered around an ancient Inhuman named Hive.]]
* ''Series/BabylonFive'' had a lot of government conspiracies. And not only [=EarthGov=] either. Especially the Centauri and to a lesser extent the Minbari, too. And then there is that whole Shadow/Vorlon-thing...
* ''Series/TheChronicle'': Everything they write about in tabloids is true.
* ''Series/StarTrekEnterprise:'' The Vulcan arc of season 4 had the Vulcan High Command justify their actions by claiming the Syrannites were terrorists who bombed Earth's embassy and then that Andoria was planning a strike against them using Xindi technology (with V'Las, the leader, hiding the fact that Archer ''destroyed'' the equipment Shran tried to steal). But then it turns out [[spoiler:V'Las was the one with the conspiracy, planting false evidence after arranging the bombing himself so he had an excuse to fight Andoria and also wipe out the Syrannites so he could keep Surak's true teachings hidden... all so he could bring about the reunification of Vulcan and Romulus]].
%%* ''Series/TheXFiles'' and its SpinOff, ''Series/TheLoneGunmen''.
[[/folder]]

[[folder:Music]]
* "Everything You Know Is Wrong" by Music/{{Chumbawamba}}, where the narrator claims responsibility of e.g. "taking scissors on the black vote down in Florida", "I was there when they landed on the moon, in a studio in Kentucky in June", "at the canteen down in Columbine, with the bags they never found", "and I hid those missing WMD's"...
* [[Music/TheRollingStonesBand "Sympathy for the Devil"]]. Seriously. [[FridgeLogic Think about it]].
* ''The Crucial Conspiracy'', Music/TheDingees' third album, had references to chemtrails, government mind-control experiments, and Majestic Twelve; and even has lyrics that could be interpreted to mean that {{Satan}} himself is involved in UFO activity.
* Music/TomSmith's "[[https://www.youtube.com/watch?v=Pm5go6mVqwU Illuminati Polka]]" plays it for laughs.
* As does {{Psychostick}}'s "[[https://www.youtube.com/watch?v=DNZj2RrrkfI Political Bum]]".
* Music/NanowarOfSteel: {{Parodied}} by "Protocols (of the Elders of Zion) of Love", a love song which tells how the singer immediately felt a connection to his LoveInterest... through the computer chips implanted in them both by Bill Gates, which along with StockFootage from ''[=InfoWars=]'' pretty much sets the tone for the rest of the song, which namedrops conspiracy theories from chemtrails to reptilians and is named after a rather infamous anti-Semitic hoax.
[[/folder]]

[[folder:Radio]]
* The "Conspiracy Theories" episode of ''Radio/TheInfiniteMonkeyCage'' says that most conspiracy theorists end up like this; after all, if the government/media/scientists are lying about ''this'', it makes sense they'd be prepared to lie about ''that'' as well, doesn't it? Apparently, research also shows that people who are prone to believing conspiracy theories don't even care if they contradict each other, and are quite happy to believe (in the example given) that the Royal Family assassinated Princess Diana, and that Diana faked her own death at the same time.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/ConspiracyX'' is an RPG (by Eden Studios) based around the concept of some or all of the conspiracy theorists being onto something.
* ''TabletopGame/DeltaGreen'' is a modern-time setting for the ''TabletopGame/CallOfCthulhu'' RPG. Not only is every possible conspiracy staged by either Nyarlatotep, Mi-Go, or some other EldritchAbomination, but the playable organization, Delta Green, is an illegal conspiracy. Why? Because official paranormal investigators are working hand-in-hand with the aliens, of course. What's even funnier is that, in the official setting, Delta Green doesn't believe in aliens, only monsters, magic, and ghosts. Of course, anyone who's up on the source material knows that all the monsters, aliens, and magic reside at the same address. (It's also worth mentioning that the aliens who are manipulating the official MIB aren't actually aliens, but artificial constructs created by the real aliens who wanted a weird but still recognizably human appearance.)
* Steve Jackson Games has at least three products set here:
** The various ''Illuminati'' card games (inspired by the above ''Literature/{{Illuminatus}}'' trilogy).
** ''TabletopGame/{{GURPS}} Illuminati'' (inspired by the success of the card games).
** ''GURPS Warehouse 23'' (inspired by [[http://www.bahneman.com/liem/x-files/warehouse.html playful Internet speculation]] on what else might be found in the government storage facility seen at the end of ''Film/RaidersOfTheLostArk'').
** Depending on how you look at it, ''TabletopGame/InNomine'' (and its offshoot, ''GURPS In Nomine'') also qualifies. ''In Nomine Anime'', a small and obscure supplement, definitely has one foot in this territory.
** Also ''TabletopGame/GURPSIlluminatiUniversity''. The "I" does stand for "Illuminati" after all. (The "U" stands for "University", and [[TheUnreveal the "O" stands for]] [[spoiler:YOU'RE NOT CLEARED FOR THAT INFORMATION! ...seriously speaking, it's never explained.]])
* ''TabletopGame/{{Paranoia}}'', though it's set in a futuristic dystopia and not the present day, definitely falls under this trope: the setting mandates that ''everyone'' is a member of some conspiracy group and probably multiple.
* The TabletopGame/OldWorldOfDarkness. Everything is being manipulated by and has always been manipulated by the [[TabletopGame/VampireTheMasquerade Vampire Elders]], the [[TabletopGame/MageTheAscension Technocracy]], [[TabletopGame/WerewolfTheApocalypse Pentex]], and [[TabletopGame/WraithTheOblivion various]] [[TabletopGame/ChangelingTheDreaming evil]] [[TabletopGame/DemonTheFallen spirits]]. At the same time. With the organizations never interacting, conflicting, or sometimes even being aware of each other. The Technocracy, in particular, seemed to have a handle on vampires and werewolves better than anyone else... then it turned out the Technocracy contained several competing conspiracies.
* The TabletopGame/NewWorldOfDarkness is getting there, except none of the conspiracies control ''everything'', just a specialized area. The Seers of the Throne make sure that magic stays out of the Fallen World so they get it all to themselves. They have their own phony Men in Black, Division Six... and we say "phony" because the ''real'' Men in Black, Task Force: VALKYRIE, operate out of the US Treasury. Then you have the medical corporation that performs experiments on supernatural creatures to find out how useful their parts are, the Catholic Church's crack monster-hunting squad, and the FBI bureau staffed with psychics who hunt down [[SlasherMovie supernatural serial killers]] and stick them in a Midwestern Guantanamo. And so on. (It's worth noting that all of the listed examples, excluding the Seers of the Throne but including Division Six, come from ''TabletopGame/HunterTheVigil''.)
* In the Fanmade Gameline ''TabletopGame/GeniusTheTransgression'', Lemuria used to be in charge of this, but now only ''thinks'' they're in charge of it. (Bizarrely, the Lemurians and the Seers of the Throne are ''unable to detect'' each other, and no one knows why.)
* This is one of the founding premises of ''TabletopGame/OverTheEdge''. Seriously, there are ''hundreds'' of them, [[GambitPileup all interfering with each other's plans...]]
* ''TabletopGame/Warhammer40000'': The following example has been deemed classification level Viridian Gamma by the Holy Inquisition of the Imperium of Man: [[spoiler:You know too much. *BLAM*]]
* ''TabletopGame/DarkMatter1999'' includes dimension-traveling lizard people, Atlantis, the Illuminati, PostModernMagik, alien bigfoot, and of course government conspiracies.
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/DeusEx'' is essentially a Conspiracy Kitchen Sink in a {{Cyberpunk}} setting.
** Let's see... [[spoiler:Area51, [[GovernmentConspiracy Majestic-12]], TheIlluminati, a [[SyntheticPlague lab-designed plague]] to [[KillThePoor cull the lower classes]], TheGreys, {{Black Helicopter}}s, TheMenInBlack (much closer to the original concept than the ones in the above movie), {{Chupacabra}}s (called "greasels" in the game), [[AliensStealCattle cattle mutilations]], FEMA as a black organization, [[UnitedNationsIsASuperpower United Nations as a black organization]], [[OneWorldOrder New World Order]], UsefulNotes/TheKnightsTemplar, corporate takeover of the government, ArtificialIntelligence secretly ruling the world, engineered gang wars, [[FalseFlagOperation fake terrorist attacks]], and even secret bases hidden under well-known American landmarks]].
** [[spoiler:To elaborate on the above: Majestic-12, an offshoot of the Illuminati that overthrew their parent organization (themselves a cabal of elite high-minded thinkers and wealthy investors ideologically descended from the Knights Templar and seeking to govern the world), is spreading a man-made virus via black helicopters both to kill off the surplus population and to control the government via their puppet-organization FEMA. They have engineered the Greasels and the Greys (using genes from animals, including bovines) as [[FictionAsCoverUp a distraction for the public]] and have created augmented Men in Black to act as their enforcers. Their ultimate plan is to reroute global communications through Area 51 and [[TakeOverTheWorld usher in a New World Order]] with themselves as the all-seeing "gods" of this world.]]
** One character claims that the maintenance men at his workplace are plotting against him when he gets a lemon-lime soda from a vending machine when he is almost certain that he pressed the orange button. His partner is skeptical, to say the least.
--->'''Anna:''' Are you ''sure'' you pressed the right button?\\
'''Gunther:''' I do not make mistakes of that kind!\\
'''Anna:''' Your hand might have slipped.\\
'''Gunther:''' No, I wanted orange. It gave me lemon-lime.\\
'''Anna:''' The machine would not make a mistake.\\
'''Gunther:''' It's the maintenance man. He ''knows'' I like orange!\\
'''Anna:''' So you think the ''staff'' has some kind of ''plot''?\\
'''Gunther:''' Yes! They do it on purpose!
** Entertainingly, [[TheCuckoolanderWasRight this is confirmed]] in ''VideoGame/DeusExInvisibleWar'' by a NPC.
---->'''Bum:''' Someone here must have really liked lemon-lime soda.
* ''VideoGame/MetalGear'' has sentient AI, top-secret government black projects, the FBI and CIA, clones, zombie cyborgs, [=UMAs=], psychics, ghosts, Communists, coverups around every corner, and also references sillier content like aliens building the pyramids and the fate of a man who went into a cave and emerged a decade later not having aged. ''[[VideoGame/MetalGearSolid2SonsOfLiberty Metal Gear Solid 2]]'' parodied itself at one point by having one of the on-disc [[AllThereInTheManual supplementary story recaps]] being a book written by the [[UnreliableNarrator most hilariously deranged conspiracy theorist]] you could possibly imagine. (To give you an idea; we don't get to read it, but the title of his previous book was ''Rays From The Loch Ness Monster -- The True Power Source Of [=UFOs=]''.) To his credit, he was extremely good at ''identifying'' conspiracies -- unfortunately, he never blamed the events on the ''right'' conspiracies, attributing TheOmniscientCouncilOfVagueness-caused disaster of the previous game to the island it was on being "an Ellis Island for the Greys". The whole farce ends with him being rescued by an invisible man whom he proudly, loudly declares is a noble SufficientlyAdvancedAlien who had taken pity on him, when it's clear to the reader that it's Solid Snake in [[InvisibilityCloak active camo]].
* ''Franchise/AssassinsCreed'' rapidly became an amalgamation of all sorts of conspiracy theories, incorporating everything from the Tunguska Event to JFK's assassination to ''the entirety of World War II'' and tracing them all back to the Templars, the Assassins, or both trying to cover up or seize something or other. It's not exactly necessary to understand how it all fits together to make any sense of the plot, fortunately, because any attempt to do so is doomed to failure, particularly when [[SufficientlyAdvancedAlien time-travelling god aliens]] get involved. Generally it's best to simply accept that the Assassins and Templars have been at each other's throats for a really long time and move on. Gets especially crazy and paranoia-inducing in ''VideoGame/AssassinsCreedBrotherhood''. Alan Turing? Murdered to prevent him from inventing too powerful computers. Cable TV? A method for transmitting brainwave-altering signals and monitoring citizens. Cell tower surveillance? Tracking all communication. These conspiracy tropes are largely used as metaphor and window dressing, and the crux of the games are mostly a skewed retelling of historical facts. Indeed the point of these games is to show how difficult and damn near impossible behind-the-scenes control over history actually is. At times the Assassins and the Templars don't have a lot to do with why certain things happened (in ''Brotherhood''. the two fight a proxy war that gets out of both of their control and tears Italy apart; in ''III'', they both back the same side in the American Revolution and mostly just fight each other as the war rages in the background so their influence over the new nation pretty much cancels out).
* Though it's not essential to play the game, the hidden messages in ''VideoGame/TheConduit'' mesh together just about every conspiracy theory under the sun. Especially [[VideoGame/{{Conduit 2}} the sequel.]]
* ''VideoGame/TheSecretWorld'' positions its setting as a world where "[[ArcWords Everything is true]]"... which includes both every conspiracy theory ''and'' [[FantasyKitchenSink every fairy tale]]. [[SuspiciouslySpecificDenial Except aliens.]]
* ''VideoGame/PerfectDark'' presents a variety of alien conspiracies as being true as the basis for its plot, including TheGreys, LizardFolk, Area 51, aliens replacing the president of the United States, ETGaveUsWiFi, and a flying saucer at the bottom of the ocean.

* The eponymous town in ''Podcast/WelcomeToNightVale'' has this trope as a basic premise, except there is no {{masquerade}}; all of it is just accepted as the normal state of things. It's implied that the world outside the town isn't ''quite'' as weird: [[OnlySaneMan Carlos the scientist]] was originally sent to investigate all the bizarre things that seem to go on there.
* Website/CollegeHumor does a marvelous [[ParodiedTrope parody of the trope]] in '[[https://www.youtube.com/watch?v=Zbl-vMN2gzo Deceptive Deceptions]]'. Among the things "uncovered" as part of a massive conspiracy embracing all of humanity in this "truthumentary" are events that ''include'': the shooting of Music/TupacShakur being arranged by the government, Dan Akroyd's role in ''Film/{{Caddyshack}} 2'' and ''Film/NothingButTrouble'' being the obvious link, the late John Candy also being in on it, Music/PaulMcCartney's replacement by a doppelgänger so he could compose "Helter Skelter" and possess UsefulNotes/CharlesManson with the spirit of the Anti-Christ: UsefulNotes/AdolfHitler, who is actually a cyberganic demon created by Nazi scientists, who then created a faux-space agency called UsefulNotes/{{NASA}} to fake the moon landings on a special stage, the UsefulNotes/JohnFKennedy assassination (which is described as "Tupac-esque") was because he boasted about putting a man on the moon in 10 years, which is actually a prehistoric hologram hiding a gigantic spaceship, ''Film/CloseEncountersOfTheThirdKind'' being made to cover this up by Dick Cheney and a pentagram of corporations that control our world (comprised of Nabisco, AOL, CITGO, Atkins, Adidas, [[ArsonMurderAndJaywalking and the New York Knicks]]), who are in turn controlled by the dual monopoly of Hooters and Website/{{Google}}. And the identity of the secret cabal that is more powerful than [[TheGovernment the American government]], the Freemasons, and TheIlluminati: [[spoiler:The College Humor staff]].
* The "artwork" of David Dees, hilariously surreal composites of edited stock photos which often feature more than one conspiracy at a time. The farther you go, the more contradictions you notice, and then it becomes clear that he probably [[AgentMulder believes them all]].
* The Website/SCPFoundation features articles based on a wide range of conspiracies, as well as an abundance of hidden conspiracies, secret societies, and mysterious cults, with the titular Foundation trying to keep it all covered up. For just one example, according to letters associated with [[https://scp-wiki.wikidot.com/scp-281-fr SCP-281-FR]], all societies that have been accused of ruling in the shadows [[labelnote:Including]] Majestic 12, TheIlluminati and the Freemasons [[/labelnote]] are members of the Global Occult Coalition (the paranormal counterpart to the United Nations, one of the Foundation's many rivals).

* ''WesternAnimation/CodenameKidsNextDoor'' has no end of conspiracies, many of them orchestrated by the KND themselves to keep their organization secret from the average adult. "Operation: M.O.O.N." revolves around the fact that one of these is the moon landing (in order to keep their moonbase from being discovered) and that they now have to fake it again after learning the American government is sending a family there to begin colonizing it.
* ''WesternAnimation/{{Dilbert}}'' has quite a few conspiracies shown over its run, many of which have Dogbert involved in some way.
* ''WesternAnimation/InsideJob2021'':
** The main characters are part of a [[EvilInc company that helps run and keep track of all of them through morally questionable means]]. This includes everything from chemtrails to cryptids to cloning celebrities to assassinations to subliminal messaging to the reptilians to Atlantis.
** One of the few conspiracies that ''isn't'' true is [[FlatWorld Flat Earth]] theory, although the HollowEarth is; Reagan's retired father Rand created it when he was still employed by the company, as part of a bet that there was no idea too dumb that he couldn't make people believe. Turns out it worked too well, but Rand continues to perpetuate it to annoy his former boss.
** Other conspiracies are true, but in different ways than you'd expect. For instance, [[MoonLandingHoax the moon landing was indeed filmed on a soundstage by Stanley Kubrick]], but this was a coverup for the fact that humanity did indeed land on the moon--and far more successfully than they should have, as the astronauts were somehow able to found a self-sustaining colony (initially a free-love commune) and secede from Earth.
