Hell Night is a 1981 American supernatural slasher film directed by Tom DeSimone, and starring Linda Blair, Vincent Van Patten, Kevin Brophy, and Peter Barton. The film depicts a night of fraternity hazing set in an old manor—the site of a familial mass murder—during which a deformed killer terrorizes and murders many of the college students. The plot blends elements of slasher films and Gothic haunted house films. Filmmaker Chuck Russell served as an executive producer, while his long-time collaborator Frank Darabont served as a production assistant.

Hell Night was written by Randy Feldman, then a recent college graduate who shopped the spec script to several film studios, among them Irwin Yablans's Compass International Pictures. Producer Bruce Cohn Curtis subsequently became involved with the project and secured the lead role for Blair, with whom he had collaborated on several films, among them Roller Boogie (1979), another Compass International release. It marked the first horror film role for Blair in several years, following her performances in The Exorcist (1973) and Exorcist II: The Heretic (1977). Principal location photography of Hell Night took place in Redlands, California at the Kimberly Crest Mansion in late 1980, with interior photography subsequently occurring in Los Angeles. The film was shot by Swedish cinematographer Mac Ahlberg. The production's shooting schedule was considerably tight, and required the cast and crew to shoot throughout the holiday season.

The film opened theatrically in August 1981, and was the final film released by Compass International Pictures. It was a minor box office success, grossing $2.3 million against a $1.4 million budget. Critical reception was generally mixed, with some critiquing it for its similarity to other slasher films as well as for Blair's performance, while others praised it for its art direction and found the film frightening. In the years since its release, the film has gone on to develop a cult following. Some critics and film scholars have noted the film for its subtext regarding social class, as well as for its depiction of Blair's character as a resourceful and intelligent final girl.
