Cujo is a 1983 American horror film based on Stephen King's 1981 novel of the same name, directed by Lewis Teague. It was written by Don Carlos Dunaway and Barbara Turner (using the pen name Lauren Currier) and stars Dee Wallace, Daniel Hugh Kelly and Danny Pintauro.

It was released in August, four months before Christine, another Stephen King story released theatrically the same year.

The film follows a mother and her son who are trapped inside their car while protecting themselves from a rabid St. Bernard.

Despite mixed reviews and modest box office receipts during its theatrical release, the film has gathered a cult following in the years since its release.
