A poltergeist (from the German ''polter'', meaning "to rumble", "to make a noise" and ''geist'', meaning "ghost" or "spirit") is a type of ghost or other supernatural entity that manifests by creating noise or moving objects.

While the term itself comes from German, poltergeist activity has been reported in nearly every culture, becoming part of the folklore in India, the United States, Japan, Brazil, and other countries. Several scientific theories regarding poltergeist activity have been proposed, including tremors, air currents, ultra-infra sound waves or unexplained losses of gravity, though true believers maintain that there is no stable scientific explanation for poltergeists. The, uh, ''not so scientific'' theories vary between ghosts and [[PowerIncontinence nonconscious, uncontrolled]] [[MindOverMatter telekinesis]].

!! Examples of poltergeists in fiction:


[[folder:Anime and Manga]]
* In ''Manga/GhostHunt'', one character's desire to be noticed ends up manifesting a poltergeist that injures several characters.

* The ''Film/{{Poltergeist}}'' movies feature (naturally) a manifestation of poltergeists that seem fixated on Carol Anne Freeling. The first movie posited that the haunting was caused by an improperly relocated cemetery, while the second suggested that a dark ritual opened a gateway between the afterlife and the living world.
* In ''Film/TheSixthSense'', Cole Sear is often the target of poltergeist-like activity from the ghosts who are trying to get his attention.
* The title character of ''Film/{{Beetlejuice}}'', most likely.
* The initial premise of ''Film/ParanormalActivity'' centers around a haunting by one of these. This theory turns out to be slightly inaccurate.
* ''Film/{{Ghostwatch}}'' follows a fictional reality program documenting poltergeist activity surrounding a woman's two daughters while the hosts debate the actual cause. At one point it appears that one of the girls is actually causing the banging and crashing because that's what people expect, but then the spirit gets mad...
%%* ''Film/ATaleOfTwoSisters''.
* "The Bell Witch" from ''Film/AnAmericanHaunting'' at first appears to be a poltergeist, though one violently obsessed with the teenage daughter of the house it's haunting.
* In ''Film/{{Ghost}}'', most dead spirits can't touch things by default, but with enough practice, a sufficiently determined (or angry) spectre can beat the crap out of you with ordinary household objects.
* In ''Film/{{Ghostbusters 1984}}'', naturally the team's first cases are basically catching ghosts that act in a typical poltergeist manner.
* ''Film/{{Nightwish}}'': A professor and some graduate students go looking for poltergeists in a deserted mansion. During several sessions looking for paranormal activity, the ghosts knock on the doors, walls, or mess with the machinery.
* The title creature in ''Film/TheBabadook'' likes to make its presence known with ominous rumbles and knocking sounds.

* In ''Literature/DragonBones'' castle Hurog is haunted by one of those ... or so it seems. When Ward encounters said entity he finds out that Oreg can take the form of a human being, but is the soul of all the castle. This is the result of dark magic that was done to him, and he is not too happy with the situation. It is hinted that, if he doesn't like someone, he can act like a regular poltergeist. However, if he does like someone, he's more the opposite, protecting Ward's younger sister from bullies and her abusive father by showing her secret doors and the like.
* In the ''Literature/HarryPotter'' series, a poltergeist named Peeves inhabits Hogwarts Castle. Unlike the other ghosts, he's a spirit of chaos rather than the echo of a person -- it's AllThereInTheManual that he "came with the building". The CrustyCaretaker considers him a mortal enemy, while everyone else just thinks he's a bit of a nuisance. The only people who can control him to any extent are Dumbledore and the Bloody Baron (Slytherin House's ghost). Peeves is fairly unique among poltergeists in that he has a physical form. Rowling [[AllThereInTheManual states]] that Peeves is an extremely powerful and ancient poltergeist, since a poltergeist is born from adolescent angst and uncontrolled magic and Hogwarts is a thousand-year-old school containing young wizards.
* In the ''Literature/OddThomas'' series, a very few particularly strong ghosts have been observed to cause poltergeist activity when they get riled up enough. One notable example is Music/FrankSinatra.
* ''Literature/{{Discworld}}'':
** In ''Discworld/WyrdSisters'', the ghost of King Verence the First discovers that he can, with immense effort, interact with physical objects. He starts out with a few grains of dust, and spends some time amusing himself by oversalting [[TheUsurper his cousin Duke Felmet]]'s porridge a pinch at a time to mess with his head, but after a while he reaches the point where he can pick up a dagger. Granny Weatherwax stops him from using it to settle the score, on the quite reasonable grounds that the dead attacking the living with intent to kill is rather unsporting.
** In ''Discworld/ReaperMan'' Death is forced into retirement, causing a whole lot of spirit activity to start manifesting through out Ankh-Morpork (and probably elsewhere as well) as the excess of life energy caused by no-one ending lives properly starts grounding itself by randomly animating objects.
** ''Discworld/AHatFullOfSky'' features Oswald, Miss Level's resident ghost. Rather than make a ruckus, however, Oswald makes sure that everything is [[SuperOCD tidy]] (an easy way to keep him occupied for a day is to spill a bowl of sugar; he'll carefully put it back grain by grain), leading Miss Level to declare him an [[InvertedTrope ondageist]].
* Poltergeists are classified under Type Two (aka the more violent, dangerous type) ghosts in ''Literature/LockwoodAndCo''. And they're bad news because unlike a conventional ghost, they can't be fought the normal way by slicing them with a sword or chucking salt or iron at them because they have no physical manifestation other than the chaos they cause. They are said to be literally everywhere and nowhere and about the only bright side of them compared to other Type Two ghosts is that their having no ectoplasm means that they can't ghost-touch you, causing you to swell up and die.

[[folder:Live Action Television]]
* Many "ghost hunting" programs request such behavior in their living-impaired quarry, in an effort to record proof of their presence.
* Cordelia's place is haunted by a friendly poltergeist in ''Series/{{Angel}}''.
* In one episode of ''Series/TheWaltons'', a poltergeist invades the family home, [[BizarroEpisode for no damn reason whatsoever]].
* In episode "Los espíritus chocarreros" of ''Series/ElChavoDelOcho'': Doña Clotilde blames the strange appearance and disappearance of objects in Vecindad to "Espíritus Chocarreros" (roughly translated as "mischievous spirits" i.e. Poltergeists). It was actually Don Ramon's during sleep walking, but no one knew that. The spiritualist session that follows in order to communicate with the spirits made this one of the funniest and fan-favorite episodes of the show.
* ''Series/BuffytheVampireSlayer'' had these in episodes like "Where the Wild Things Are". It had the Scooby gang playing spin the bottle at a place haunted by ghosts and poltergeists.
* ''Series/{{Supernatural}}'': in episodes like "Home" and "Swap Meat".
* ''Series/{{Charmed}}'' had a episode about a poltergeist haunting a place.

* During [[SpookySeance the Seance]] in ''Pinball/TheAddamsFamily,'' The Power disrupts the movement of the ball.

[[folder:Tabletop Games]]
* ''TabletopGame/WraithTheOblivion'' gives us poltergeist powers in the form of the Outrage Arcanos, which allows a wraith to affect physical objects, often through brute force, and the Pandemonium Arcanos, which produces creepy reality-warping effects ranging from cold spots to blood on the walls to altered perception of time. The semi-sequel, ''TabletopGame/{{Orpheus}}'', gives us the Poltergeist, a Shade (or class of ghost/projector) with a talent for throwing about objects with telekinetic force and boosting the physical capacities of their ectoplasmic bodies.
* ''TabletopGame/DungeonsAndDragons'' has had several versions of poltergeists as monsters, including in the [=AD&D=] ''Fiend Folio'' and the Basic D&D Companion rules.
* ''TabletopGame/{{GURPS}}'''s Horror supplement features a Poltergeist template that can be applied to the Haunt meta-trait.
* In ''TabletopGame/Warhammer40000'', the Crimson Slaughter are a warband of Chaos Space Marines who are haunted by disembodied voices. During battle these voices manifest as malevolent poltergeist activity amongst the enemy ranks, filling vox-channels with ominous whispers and causing inanimate objects to ooze blood or float around as if manipulated by invisible hands.

[[folder:Video Games]]
* In ''VideoGame/BeyondTwoSouls'', protagonist Jodie has been connected her entire life to an "entity" called Aiden. Aiden can [[MindOverMatter move objects]], [[WalkingTechBane short out electronics]], protect Jodie with a [[BarrierWarrior magical shield]], [[GrandTheftMe possess people]] and more. Jodie can [[KidWithTheLeash exercise some degree of control over him]] - thankfully - though doing this for too long will give her a PsychicNosebleed.
* In the first ''VideoGame/{{Splatterhouse}}'' game, a poltergeist boss attempts to drop a chandelier on your head.
* In ''VideoGame/MegamanBattleNetwork'', you can get a chip called "Poltergeist" that replicates a poltergeist's common traits by picking every item on the battlefield and flinging them at enemies. It's very deadly if you have enough items on field at once.
* The Prismriver sisters of ''VideoGame/{{Touhou}}'' are poltergeists. Something of a cross between the 'ghost' and 'uncontrolled psychokinesis' theories; they're artificial ghosts created by an unstable girl.
* ''VideoGame/CastlevaniaSymphonyOfTheNight'' has the Spectral Sword causing this, as well as the Ouija board. Once you get the perk that lets you see the enemy's name, you'll occasionally find an actual Poltergeist in the game.
* In ''VideoGame/{{Geist}}'', ''you'' play as a poltergeist. You can cause objects to bang around and break in order to scare guards and animals, and once they're scared enough you can [[DemonicPossession possess]] them and use them to accomplish physical tasks.
* Many of the early manifestations in ''VideoGame/{{Paranormal}}'' consist of poltergeist activity.
* The Dark Presence in VideoGame/{{Alan Wake}} sometimes uses possessed items against you that you must defend against with your flashlight. This can range from barrels or wheel to entire vehicles, the latter serving as a boss battle.
* ''[[{{VideoGame/Shiver}} Shiver: Poltergeist]]'' features a female poltergeist who uses pyrokinesis in addition to throwing stuff around.
* ''VideoGame/HauntingStarringPolterguy'' is a comedy-horror game where you play as a poltergeist named Polterguy. You're actually the ghost of a punk teen killed by a defective skateboard and your objective is to terrify the negligent CEO (and his family) until he learns his lesson, mostly by possessing objects in the house and making them do grotesque things, or sometimes simply making them fly around.
* ''[[http://armorgames.com/play/7195/haunt-the-house Haunt The House]]'' is an indie computer/mobile title which has the players take on the role of a cute little ghost, whose objective is to scare noisy partygoers out of his house so he can get some rest, which he does by possessing objects and making them move or perform a 'scary' action such as belching black ichor or popping skeletons out of drawers.
* In ''VideoGame/EarthboundBeginnings'', one of these attacks Ninten's house at the very start of the game. [[spoiler:Except that it's actually Giegue's psychic influence that makes inanimate objects come to life, and making people and animals hostile.]]

* ''Webcomic/ChampionsOfFaraus'' has Poltergimes. A [[OurSpiritsAreDifferent type of trickster spirit]] which is the [[FusionDance combined form]] of a ghost, a Mischevie (another trickster spirit) and a slime. Like the component mischevie, they [[ItAmusedMe like to mess with people,]] (although unlike mischivies who mainly cause mischief, Poltergimes might also feel like causing someone to die if the mood hits them right) and are able to possess and haunt objects, as well as being able to create blue fire. The Poltergime [[spoiler:that haunts the house in Yorken that Daryl buys]] is seen doing things like making chandeliers fall, making objects bleed, and fliping furniture around.

* In one episode of ''WesternAnimation/{{Beetlejuice}}'', BJ meets his match in a ''poultrygeist'' (manifesting as a spectral chicken) who is preventing him from sleeping. The Neitherworld medium ([[MST3KMantra just roll with it]]) he and Lydia recruit to get rid of it gets really excited, because poultrygeists can answer any question. [[spoiler: They ultimately get rid of it by asking questions that have no answer... and then 400 more show up.]].
* Most of the ghost and spirits hunted in ''WesternAnimation/TheRealGhostbusters'' are the typical poltergeist.
* What's seems to be a Poltergeist (and mentioned as such by name) affects the MIB headquarters in the HalloweenEpisode of ''WesternAnimation/MenInBlack''. As the show is sci-fi it turns out the Poltergeist was caused by an interdimensional alien life form.
