This is the character in {{Cop Show}}s, {{Detective Drama}}s, and Espionage Thrillers that everyone despises. Even the cops who make use of his services hate him. He is beneath the level of more dignified, "honest" crooks. He is a low level version of the KnowledgeBroker; perhaps even the minion of one. But where a KnowledgeBroker is high status and has an arbitrarily greater reputation, this character is just a stoolie. (This difference is sort of like the difference between a courtesan and a street-walker... they are both prostitutes, but one is considered "high class".)

The Informant lives in a miserable fashion selling information. But he is needed, so he is tolerated. Sometimes a sort of patronizing affection is granted him. In such a case, he is likely to be a LovableCoward as well as a LovableTraitor. Probably there are those who will not find him lovable...

A subtrope of KnowledgeBroker and IndispensableScoundrel. MysteriousInformant is a SisterTrope to, and TheStoolPigeon is a SubTrope of, The Informant. This trope may be averted entirely if a particular crime boss or criminal empire is [[TheMobBossIsScarier considered too scary to inform on]].

Not to be confused with 2009 Matt Damon film ''Film/TheInformant2009'', which is actually about a [[TheStoolPigeon Stool Pigeon]], kind of.

Informants fear prison, since they probably become a PariahPrisoner, fearing PrisonRape or lethal violence. Compare BakerStreetRegular for a more sympathetic version of the trope. If this character happens to be a prostitute, she's a ShadyLadyOfTheNight.

* Juan Martinez in ''Film/RunningScared1986''. He's a second generation stoolie.
* The informant in ''Film/TheFrenchConnection'' is portrayed more seemingly realistically than the norm described in the trope description at the top of this page, perhaps because the film is based somewhat closely on a true story.
* Clarence Darlington in ''Film/LakeviewTerrace'' is a small time drug dealer and DirtyCop Abel Turner's informant.
* In the Creator/GuyRitchie movie ''Film/RockNRolla'', the London underworld is puzzled by he identity of an informant whose testimony has been putting away multiple well connected gangsters. At the very end of the film [[spoiler:it's revealed to be TheDon himself, [[LondonGangster Lenny]]. Lenny's men quickly and ruthlessly turn on him, especially since some of them, including TheDragon have gone to prison based on that testimony]].
* In ''Film/TheFriendsOfEddieCoyle'', Eddie (Creator/RobertMitchum) is what can only be termed an aspiring informant. [[spoiler:Ironically he's assassinated by a man who turns out to be an informant himself.]]
* In ''Film/HellraiserInferno'', Detective Joseph has an ex-con snitch named Bernie running an icecream truck, whom he abuses for information on the Engineer. Then again, Bernie is implied to have been sent to prison for being a pedophile. [[spoiler:The Engineer tortures and murders the informant on camera to spite Joseph.]]
* In ''Film/BlackMass'' Whitey Bulger pretends to be one, but in reality he's mostly feeding the FBI things they already knew, and in any case he's informing on the Italian mafia so he and the rest of TheIrishMob can replace them as head of organized crime in Boston. Later, a real informant rats Whitey out for smuggling guns to the IRA, and Whitey kills him with the contempt usually associated with a rat.
* ''Film/LeDoulos'': Maurice thinks that his partner-in-crime Silien has become a police informant. He's wrong; someone did rat him out and nearly get him killed during the failed robbery, but Silien isn't the one.
* ''Film/MysteryRoad'':
** Jay gets a lot of information about Julie his uncle, and gives him some money to play Bingo with afterwards.
** Later, Jay gives a boy who found Julie's phone some money and permission to god his (unloaded) gun while asking a few questions.
** Johnno claims that local drug dealer Wayne is his informant after Jay arrested him and later events (Wayne seen being dragged into a car roughly by several other gang members) imply this is true.
* [[ObfuscatingDisability Fake blind man]] Sightless in ''Film/DickTracysDilemma'' sells information to Dick Tracy.

[[folder:Literature]]
* Subverted by Nick the Nose from Donald Sobel's ''Literature/TwoMinuteMysteries'' series. He ''wants'' to be this, but his leads are always phony - he just wants the rewards from the police for case leads, and Dr. Haledijan always spots the discrepancies in his stories.
* [[spoiler:David]] in Creator/ChinaMieville's ''Literature/PerdidoStreetStation'' sells out Isaac to the militia as part of his work as a paid informant.
* ''Literature/{{Discworld}}'':
** Lord Vetinari gets intel from the city's beggars, mostly by way of unfounded rumors that he pays for information. And the City Watch under Commander Vimes gets information from similar sources, as well as some of the pettier of petty criminals, who have an almost jocular relationship with the lawmen. It's mentioned that the Watch House break room is populated by a collection of "petty crooks, informants and ex-watchmen, some of whom were the same people." Vimes signs off on the doughnuts, since the information they bring in is well worth the price.
** In ''Literature/NightWatchDiscworld'', Nobby Nobbs started out as one of these, and eventually became a real member of the Watch. Though not a particularly good one.
* ''Literature/ForestKingdom'': In the ''Hawk & Fisher'' spinoff series, the City Guard has them, though Hawk and Fisher don't much approve of such types.
* ''Literature/HoshiAndTheRedCityCircuit'' has Hoshi's tinker friend Kelvin, who went into [[TheCityNarrows Shirring Point]] four years ago after almost getting beaten to death by riot cops and never came out.

* ''Literature/TheFourthLawOfRobotics''. Literature/TheStainlessSteelRat goes to the WrongSideOfTheTracks looking for a man willing to sell him information on the renegade robot. He takes a hundred bucks off Slippery Jim, then pretends to know nothing and refuses to return the money, so Jim forcibly injects him with a TruthSerum to get the information he wants.

[[folder:Live-Action TV]]
* ''Series/BreakingBad'': The cartel member Tortuga, who appears in the episode ""Negro y Azul", lives a luxurious double-life as both drug runner and DEA snitch. He only appears in one episode because... well, let's just say it's a dangerous life ratting out the cartel to the police...
* Willy the Snitch from ''Series/BuffyTheVampireSlayer'' runs a dive patronised by demons, and lives up to his name.
* In ''Series/MiamiVice'', Crockett and Tubbs regularly called upon Izzy "The Snitch" Moreno and Neville "Noogie" Lamont to get information on whatever big plot was going down. The two cops treated the latter like some unpleasant form of fungus, while the former was treated like a favored pet.
%%* In ''Series/{{Informer}}'', the whole series is this, and it's naturally PlayedForDrama.
* ''Series/InPlainSight'', by its very nature, often deals with Informants who are now on the run from their former employers.
* While very few of the Informants were ever actually ''shown'', the detectives on ''Franchise/LawAndOrder'' often had regular informants they relied on. Detective Rey Curtis often referred to an entire network of confidential informants he had from his days as a vice cop.
** Fin from ''Series/LawAndOrderSpecialVictimsUnit'' had a number of these as well, most of whom he'd acquired from his time in Narcotics.
** One or two episodes make it clear the NYPD expects cops to register their CI's with the department, and frowns on officers who keep informants "off the books".
* In the episode of ''Series/FantasyIsland'' with the two old actors who used to star in a cop show together, their characters had an informant they used to rough up when they wanted information. When they get stuck in a real-life version of the show, the informant shows up with a massive grudge against them for the way they used to treat him.
%%* Alexei, a Russian taxi driver in Moscow, in ''Series/{{JAG}}'' a LovableRogue that works for "the highest bidder", but develops a crush on Mac.
%%* Merl from ''Series/{{Angel}}''.
* ''Series/TheWire''
** Bubbles is a frequent informant to the police, and on very friendly terms with the officer he worked for. Kima in particular even helps him when he tries to quit heroin. On the other hand, some cops such as [[DumbMuscle Herc]] just use him as a tool and allowed Bubbles to get beaten within an inch of his life, so Bubbles very deservedly sets up Herc to arrest somebody with connections, resulting in his firing.
** In the fourth season, Randy's story is used to show the darker side of this trope and illustrate how becoming a police informant can completely ruin your life, even if you're in middle school.
* Several one-off characters in ''Series/TheSweeney'', whose portrayals ranged from "contemptible but necessary" to actually fairly sympathetic. Of course, one of the show's central themes was that the cops and the cons weren't that different.
* ''{{Series/Guerrilla}}'': One of the black radicals turns out to be a police informant. He points out the leader of the protest for the police, who beat him to death. Pence also has a female one, whom he's involved with and fathered a son by.
* ''Series/StarTrekEnterprise''. While battling time agents in [=WW2=] New York, Captain Archer is put in contact with a man who sells information to them. However the informer frankly admits that [[SurprisinglyRealisticOutcome he makes most of the stuff up]].
* ''Series/KolchakTheNightStalker''. IntrepidReporter Carl Kolchak uses them from time to time.
** Kolchak goes to talk to morgue attendant Gordon Spangler, AKA "Gordy the Ghoul", whenever he needs information about dead bodies and crimes related to them. Mr. Spangler requires Kolchak to bribe him for the information, sometimes by buying numbers in a lottery and sometimes by direct payments.
** In the episode "The Zombie", Kolchak twice gets information about the local underworld from a tipster named "The Monk".
* Parodied in ''Series/PoliceSquad''. Detective Drebin visits Johnny the shoeshine boy when he needs information. He asks him "What's the word on the street about (whatever he's investigating)?" and Johnny will always say something like "How should I know?" Then Drebin will hand over some cash, and Johnny will immediately supply him with just the information he is looking for, no matter how unlikely it is that a shoeshine boy would know about it. They later expanded the joke by having celebrity guest stars go to Johnny after Drebin leaves and ask him questions about esoteric knowledge in their specialties, which Johnny can always answer, for a fee, of course. For instance, a surgeon asks him how to do a rare surgical procedure, Dr. Joyce Brothers asks him about the Peter Pan Effect, and Dick Clark asks him to explain ska music, and then purchases a magical youth preserving face cream from him.
* ''Series/CrazyLikeAFox'': "The Man Who Cried Fox" features a former mobster who's written a tell-all book.
* ''Series/{{Hightown}}'': Ray has a few of these, and encourages his team to make use of theirs. His boss also makes him get another one when the first dies.
* ''Series/HomicideLifeOnTheStreet'': In Kellerman's introductory two-parter episode, he has an informant named Zithead Mazursky who provides him with tips on Baltimore's arson scene. [[PutOnABus He disappears afterwards, presumably since Kellerman transferred to Homicide and thus wouldn't need an arson-based informant anymore.]]
* ''Series/YoungSheldon'': While the details aren't made clear, it's implied that the school where George Sr. previously worked was involved in a recruiting scandal. When he went to the authorities, he ended up being fired and had to move his family to find a new job.
* ''Series/{{CSINY}}'':
** Recurring character Terrence Davis makes his first appearance in "[[Recap/CSINYS05E03 Turbulence]]." He's an ex-con who agrees to become Flack's confidential informant in exchange for a plea deal on a parole violation for keeping a firearm in the office of the nightclub he now owns. In "[[Recap/CSINYS05E25 Pay Up]]," he gives Flack the name and address of one of the suspects in the killing of Flack's partner.
** In "[[Recap/CSINYS09E09 Blood Out]]," Narcotics officer Robert Hicks has a confidential informant named Raymond Cruz who, at first, impresses Mac by putting them on the trail of a murder suspect they're after, but [[spoiler:who eventually turns out to be the culprit.]]
* ''Series/{{Daredevil|2015}}'': The plot of season 3 kicks off when Wilson Fisk ostensibly agrees to become an FBI informant for Special Agent Ray Nadeem to protect his fiancée Vanessa Marianna from criminal prosecution. In actuality, this is a deal where Fisk calls all the shots, as after manipulating the FBI into letting him out of prison, he proceeds to use them as enforcers to eliminate his rivals and turn himself into a one-stop shop for bribery and protection for whatever criminals are left.
* ''Series/{{Deputy}}'':
** Daisy, a kind transgender inmate in the LA County Jail, gives information to the cops about her ex-boyfriend Villalobos, a gangster. After he learns about it and ends up in the same jail, Villalobos nearly kills her for doing this.
** A suspect in a deputy's murder turns out to have really been his informant, only behaving hostile to him as cover.
** In "10-8 Firestone" Hollister runs into Valeria, a woman who once had been informant when he worked narcotics. They were also involved, as he admits to his wife while assuring her it's long over. Valeria's now a money courier for criminals and gives him information about human trafficking that she knows of. She gets a new life in WitnessProtection because of this, and they have a bittersweet farewell.
** "10-8 Agency" sees confidential informants being killed all over LA, which the Sheriff's Department starts investigating. It turns out that the names were given by a former DirtyCop to the DA's Office as a part of his PleaBargain, then leaked as a plant is working there.
* ''Series/TheSopranos'': As a CriminalProcedural focusing on the New Jersey mob, this comes up periodically, and rarely by choice, as it's extremely risky business ratting on the TheMafia, especially when the FBI [[PoliceAreUseless has little to no way to actually protect the informants]] and [[DirtyCop is riddled with corruption]]. The success ''and'' survival rate of informants over the course of the show was basically zero.
** Early in the series is [[spoiler:Jimmy Altieri, who returns after being apparently bailed out from an FBI bust. [[TooDumbToLive He immediately starts asking incriminating questions about the Columbian drug money Tony hijacked]], making Tony immediately suspicious. Tony's suspicions seem to be confirmed when Jimmy calls in a meeting of the capos just to discuss stuff they already know, as even the usually adversarial Junior immediately agrees with Tony after the meeting. For his punishment, Jimmy is lured by Christopher to a hotel room, where he's shot in the back of the head by Silvio Dante and his corpse has a dead rat stuffed into its mouth for added poetic measure.]]
** More significantly is [[spoiler:Salvatore "Big Pussy" Bonpensiero, one of Tony's closest friends. A dirty cop on Tony's payroll actually correctly pegs Big Pussy as the informant, but Tony comes to the assumption that he mistook Pussy for Jimmy due to their similar appearances and being caught in the same FBI bust. He gradually comes to the realization that Pussy is ''also'' an informant, although it's seen from Pussy's perspective that he was forced to be a rat, as he was otherwise facing a life sentence for heroin deal, giving the FBI as little useable evidence as possible and lies about meetups with Tony, basically providing them nothing worthwhile. Nonetheless, Tony eventually realizes the evidence is undeniable and considers it a deep betrayal. Tony, Paulie, and Silvio trick Pussy out onto a boat, get him to confess, simultaneously shoot him dead, and then dump his body in the ocean.]]
** Christopher's [[spoiler:fiancee Adriana la Cereva is coerced into being an FBI informant by a friend who turns out to be an undercover agent. When the FBI pressures her [[SadisticChoice to find more info on Tony or get sent to jail for 25 years for cocaine smuggling]], she actually ''confesses'' becoming an informant to Christopher, in the hopes that he'll abandon his criminal life and go into witness protection with her. Unfortunately, given the difficult choice, Christopher ends up reluctantly siding with the family, and Silvio is tasked with taking out Adriana.]]
** [[spoiler:Black Jack Massarone is a construction company owner who gets manipulated by Tony into a protection racket. He eventually gets fed up and becomes an informant, although Tony quickly becomes suspicious when one of his soldiers informs him an FBI car was staking out one of his meeting with Jack. [[SpottingTheThread His suspicions turn to apparent confirmation]] when Jack asks if Tony lost weight in their next meeting, something he never would have dared to ask before. Jack is last seen as a corpse in the trunk of a car with a golf club cover stuffed in his mouth as a message to the FBI.]]
** [[spoiler:Ray Curto is the most successful informant in the show, [[DamnedByFaintPraise which isn't saying much]]. Unlike the other informants, he was fully willing and cooperative, but dies of a stroke in the midst of a meeting with his handler, [[HisNameIs right as he's about to impart some damning evidence about Tony]], so he ends up giving FBI diddly-squat worthwhile.]] [[DramaticIrony None of the other mobsters find out he was ever a rat and honour him with great respect at his funeral]].
** [[spoiler:Eugene Pontecorvo is a minor character, who gets some focus after receiving a huge inheritance from a deceased relative. Seeing no more reason to keep up his criminal life, his wife pressures him to quit so they can move to Florida. He asks Tony if he can retire, but [[ResignationsNotAccepted Tony refuses his request because he took an oath]], and this is compounded by the revelation that he was a government informant, and the FBI also denies his request to retire, because they require more evidence on Tony in the wake of Curto's passing. [[TrappedInVillainy Feeling there's no other way to escape]], [[DrivenToSuicide Eugene kills himself by hanging]].]]
** It's indicated in the last episode that [[spoiler:Carlo Gervasi seems to have turned state witness against Tony, although this isn't outright confirmed. The implication here is that, [[UncertainDoom even if Tony wasn't actually shot dead at the end]], his future is grim either way now that one of his closest capos was going to testify.]]

* Josh Stone from ''WesternAnimation/{{Recess}}'' was closer to this trope than TheStoolPigeon, as not only was he undercover for the Superintendent Skinner, he was also not even a kid. He did such a good job at covering his tracks that TJ and his friends initially thought Randall was behind their being snitched on, [[NotMeThisTime despite Randall's insistence that he did not]], until they literally chased him into a bathroom.
