Coffy is a 1973 American blaxploitation action film written and directed by Jack Hill. The story is about a black female vigilante played by Pam Grier who seeks violent revenge against a heroin dealer responsible for her sister's addiction.

Produced and distributed by American International Pictures (AIP), Coffy was the third Jack Hill film to star Grier, after The Big Doll House and The Big Bird Cage. Grier would go on to boost her career as the leading "femme fatale" of blaxploitation for the rest of the 1970s.

An emergency room nurse named Flower Child Coffin—usually referred to as "Coffy"—seeks revenge against the people responsible for her younger sister Lubelle's heroin addiction and the widespread violence in her city. Under the guise of a prostitute willing to do anything for a drug fix, she lures a drug pusher and a mob boss to their residences, killing them. After she exacts her revenge, Coffy returns to her job at a local Los Angeles hospital.

After her shift, Coffy's police friend Carter offers to drive her home. Carter is a straight-shooting officer who is not willing to bend the law for the mob or the thugs who have been bribing officers at his precinct. Coffy doesn't believe his strong moral resolve until two hooded men break into Carter's house while she's visiting him and beat Carter, crippling him. This enrages Coffy, giving her further provocation to continue her work as a vigilante, killing those responsible for harming Carter and her sister.

Coffy's boyfriend, Howard Brunswick, is a city councilman. Coffy admires Brunswick for his contributions to the community. Brunswick announces his plan to run for Congress and his purchase of a night club. Coffy's next targets are a pimp named King George, one of the largest suppliers of prostitutes and illegal drugs in the city, and Mafia don Arturo Vitroni, a criminal associate of George's.

Coffy questions a former patient, a known drug user, to gain insight into the type of woman King George likes and where he keeps his stash of drugs. Coffy shows no sympathy for the drug-addled woman and abuses her as she looks for answers. With the information she gets from the woman, Coffy tracks down George and poses as a Jamaican woman looking to trick for him.

George, immediately interested in her exotic nature, hires her. One of the prostitutes becomes jealous. Later that day, Coffy and the other prostitutes get into a massive brawl. Coffy wins, which attracts mob boss Vitroni, who demands to have her that night. Coffy plans to kill Vitroni, but before she can shoot him, his men overtake her. She lies and tells Vitroni that King George ordered her to kill him, which makes Vitroni order George to be killed. Vitroni's men kill George by lynching him by the neck from his car, which they drive through an open field.

Coffy then discovers Brunswick, her clean-cut boyfriend, is corrupt when she's shown to him at a meeting of the mob and several police officials. He denies knowing her other than as a prostitute, and Coffy is sent to her death. Coffy seduces her would-be killers. They try injecting her with drugs to sedate her, but she had replaced the illicit drugs with a sugar solution earlier. Faking a high, she kills her unsuspecting hitman with a pointed metal wire she fashioned herself and hid in her hair, by stabbing him in the jugular vein.
