Red Sonja is a 1985 American epic sword-and-sorcery film directed by Richard Fleischer, and written by Clive Exton and George MacDonald Fraser. It is based on the character created by Robert E. Howard, Red Sonya of Rogatino, who also inspired the comic book character of the same name.

The film introduces Brigitte Nielsen as the title character, with Arnold Schwarzenegger, Sandahl Bergman, Paul Smith and Ronald Lacey in supporting roles. As in Howard's Conan, Red Sonja takes place in the Hyborian Age, a fictional prehistoric time previously depicted in the films Conan the Barbarian (1982) and Conan the Destroyer (1984).

It was theatrically released in the United States on July 3, 1985, by MGM/UA Entertainment Co. Upon release, the film was a critical and commercial failure, grossing $6.9 million under a budget of $17.9 million.
