Hellraiser: Bloodline (also known as Hellraiser IV: Bloodline) is a 1996 American science fiction horror film and the fourth installment in the Hellraiser series, which serves as both a prequel and a sequel. Directed by Kevin Yagher and Joe Chappelle, the film stars Doug Bradley as Pinhead, reprising his role and now the only remaining original character and cast member. It also features Bruce Ramsay, Valentina Vargas, Kim Myers and Adam Scott in his first major film role. It was the last Hellraiser film to be released theatrically, the last to have any major official involvement with series creator Clive Barker and also the final installment in chronology.

Hellraiser: Bloodline had a troubled history and, after completing the film, original director Yagher left the production after distributor Miramax demanded new scenes be shot. It was subsequently completed by Chappelle. The new scenes and re-shoots changed several characters’ relationships, gave the film a happy ending, introduced Pinhead earlier, and cut 25 minutes. Yagher felt the changes diverged too strongly from his vision and was granted the Alan Smithee pseudonym, an alias used by directors who want to go uncredited. Miramax released it in the United States on March 8, 1996, where it grossed $9 million. It was not screened for critics and received negative reviews.
