Sorority House Massacre is a 1986 American slasher film written and directed by Carol Frank, and starring Angela O'Neill, Wendy Martel, Pamela Ross, and Nicole Rio. It follows a sorority pledge who experiences déjà vu in the sorority house when a murderer begins killing the residents over Memorial Day weekend. It is the first film in the Sorority House Massacre trilogy, a spin-off of The Slumber Party Massacre trilogy and second film trilogy in Massacre franchise; like its predecessor, it was entirely written and directed by a woman.

The film was developed by Roger Corman's New Concorde Studios based on the prior commercial success of The Slumber Party Massacre (1982), and Frank, who had worked as a personal assistant to that film's director, was hired to write and direct the project. Shot in Los Angeles, Sorority House Massacre had its world premiere in Pittsburgh, Pennsylvania on October 10, 1986. It received a largely negative reception on release, often criticized for being "too similar" to Halloween (1978), while it has been retrospectively praised for its characters and feminist themes and went on to acquire a cult following.

It was followed by two sequels, Sorority House Massacre II and Sorority House Massacre III: Hard to Die (both 1990), directed by Jim Wynorski.
