A genre with characters who specialize in investigating reports of paranormal activity - in other words, {{Occult Detective}}s.

The paranormal occurences can be a hoax or the real thing.

When actual supernatural forces are in play, the characters can either be no physical match for them, or they can fight the supernatural on equal terms, either physically, or technologically.

According to [[http://web.archive.org/web/20061216160748/www.gwthomas.org/athenodorus.htm the Ghostbreakers website]] the genre is in fact OlderThanFeudalism starting with the letter ''[[http://www.bartleby.com/9/4/1083.html To Sura]]'' by Pliny the Younger.


[[folder: Anime & Manga]]
* ''Anime/{{Karas}}'': Kure and Sagisaka work as Shinjuku's sole paranormal police task force, making them a bit of a joke to the rest of the police.
* ''Manga/GhostHunt'': ExactlyWhatItSaysOnTheTin.
* ''Anime/PhantomQuestCorp'', a.k.a. ''Yuugen Kaisha'', is exactly what it sounds like: a privately run agency that investigates the paranormal and the supernatural. Many of their assignments are commissioned from U Division's [[OccultDetective Detective Karino]], as a personal favor to Phantom Quest's president, [[LoveInterest Ayaka]] [[ChristmasCake Kisaragi.]]
* ''Manga/GhostTalkersDaydream'': [[MysticalWhiteHair Misaki]] [[{{Dominatrix}} Saiki]] has had the ability to see spirits, since childhood, and eventually learned she was a medium[[note]]a spiritual conduit by which the deceased can communicate with the living[[/note]]. As such, spirits are naturally drawn to her. She doesn't have a firm of her own, so she accepts assignments from the Livelihood Preservation Group, as an exorcist. But she mainly does it so the spirit in question will move on [[ReluctantHero and leave her alone.]]
* ''Manga/YuYuHakusho'' started out this way in the beginning, but quickly dropped the paranormal mystery aspect of the series in favor of paranormal action.
* ''Manga/TasogareOtomeXAmnesia'': The [[ExactlyWhatItSaysOnTheTin Paranormal Investigation Club]] tends to function this way, more so in the manga.
* The Blue Clan, Scepter 4 in ''Anime/{{K}}'' is a supernatural police division, tasked with cases involving Strains, the series' rogue supers. Inverted in that the main character is an OrdinaryHighSchoolStudent who's been framed for a murder, on the run with both Scepter 4 and the Red Clan after him. A lot of the side materials have them clashing ([[FoeRomanceSubtext in more ways than one]]) with the Red Clan, who are essentially a superpowered street gang.

* Doctor Thirteen, the Ghost Breaker. A die-hard skeptic, originally every haunting he investigated turned out to be fake, but then Thirteen started teaming up with ComicBook/ThePhantomStranger and became part of the Franchise/DCUniverse, and his skepticism has been played for laughs ever since. DependingOnTheWriter he may or may not have some kind of unconscious AntiMagic power that turns actual supernatural monsters into mundane things.
* ''Hoax Hunters'' is about a group of paranormal experts who investigate supernatural activity -- and cover it up by using their TV show to present it all as a hoax or a tall tale that got out of hand. They have an obscure connection to the government, and have been operating in some form for decades.
* The Bureau for Paranormal Research and Defense (ComicBook/{{BPRD}}) of the Mignolaverse, former employer of ComicBook/{{Hellboy}}, is an entire government agency dedicated to paranormal investigation.

[[folder:Films -- Live-Action]]
* ''Franchise/{{Ghostbusters}}'' -- "Who you gonna call?" Although they're more like a decontamination crew than detectives or investigators.

* The standard plot of the ''Literature/CarnackiTheGhostFinder'' stories by Creator/WilliamHopeHodgson, a contemporary of Conan Doyle. Particularly notable for the fact that he regularly investigates both [[ScoobyDooHoax hoaxes]] ''and'' genuine supernatural menaces, in roughly equal proportion.
* In the ''Literature/KittyNorville'' series, Kitty is successful, a rising star in the radio culture. Her radio show, ''The Midnight Hour'', has become an overnight sensation, providing outre music, observations about the bizarre, and call-in radio advice for the loners, the odd, and the unusual. Initially she doesn't investigate the supernatural herself, merely research, discuss, and theorize about it, but as time goes on she ends up having to to some degree in order to protect herself and those she cares about from the various supernatural threats she encounters. She also meets an actual cable TV show in book six, ''Paradox PI'', that is very much modeled after ''Series/GhostHunters''.
* ''Literature/MorrisAndChastainInvestigations''.
* ''Literature/TheDresdenFiles''. The trope title is even part of Harry Dresden's yellow pages ad.

* ''Literature/{{Haunted 1988}}''
* ''Literature/LockwoodAndCo''
* ''Literature/{{Paranormalcy}}''

** ''Series/DestinationTruth'': A "reality" TV series. Usually half of the episode segments feature a haunting investigation while the rest deal with cryptids.

Conversely, other paranormal investigators regard the Institute as a joke.
