Freaky Friday is a 1976 American comedy film starring Jodie Foster as Annabel Andrews and Barbara Harris as her mother.

The film is based on the novel of the same name by Mary Rodgers, in which mother and daughter switch bodies and get a taste of each others' lives. The cause of the switch is left unexplained in this film, but occurs one Friday the 13th, when Mrs. Andrews and Annabel, in different places, say about each other at the same time "I wish I could switch places with her for just one day." Rodgers adds a waterskiing subplot to her screenplay. The cast also includes John Astin, Ruth Buzzi, Dick Van Patten, and Charlene Tilton.

Neither Barbara Harris nor Jodie Foster did any actual waterskiing in the film. In both cases, these scenes were achieved with the use of professional waterskiiers in long shot on location, and cutaway shots of the actresses in front of a green-screen projection. Foster did, however, play field hockey in the film.

The film was remade twice, the first being a 1995 television film starring Shelley Long and Gaby Hoffmann. The second was a 2003 feature length film directed by Mark Waters, with Lindsay Lohan as the daughter and Jamie Lee Curtis as the mother.
