Trilogy of Terror is a 1975 American made-for-television anthology horror film directed by Dan Curtis and starring Karen Black. It features three segments, each based on unrelated short stories by Richard Matheson. The first follows a college professor who seeks excitement with her students; the second is about twin sisters who have a bizarre relationship. These two segments were adapted by William F. Nolan. The third, adapted by Matheson himself, focuses on a woman terrorized by a Zuni fetish doll in her apartment. Black stars in all three segments, and plays dual roles in the second.

The film was first aired as an ABC Movie of the Week on March 4, 1975. Black initially turned down the project, but reconsidered when her then-husband, Robert Burton, was cast in the first segment "Julie". A television film sequel titled Trilogy of Terror II, written and also directed by Dan Curtis, was released in 1996.
