Hellraiser is a 1987 British supernatural horror film written and directed by Clive Barker in his directorial debut. Based on Barker's 1986 novella The Hellbound Heart, the film's plot concerns a mystical puzzle box that summons the Cenobites, a group of extra-dimensional, sadomasochistic beings who cannot differentiate between pain and pleasure. It stars Andrew Robinson, Clare Higgins, Ashley Laurence, and Doug Bradley as the leader of the Cenobites.

Development of the film began before Barker's novella was published. Disappointed by previous adaptations of his work, Barker elected to direct himself, appropriating several actors and crew from his earlier career as a playwright. With the backing of independent producer Christopher Figg and financing from New World Pictures, filming took place in London in autumn 1986.

Hellraiser had its first public showing at the Prince Charles Cinema on 10 September 1987. It was widely released in the United Kingdom by Entertainment Film Distributors, and was a considerable commercial success, grossing $30 million from its $1 million production budget. Critical reception was initially divided, but the film has since been evaluated as a classic of the horror genre.

The film was followed by nine sequels, the first seven of which featured Bradley reprising his role as Pinhead. A reboot, also titled Hellraiser and executive produced by Barker, was released in 2022.
