Frenchman's Creek is a 1944 adventure film adaptation of Daphne du Maurier's 1941 novel of the same name, about an aristocratic English woman who falls in love with a French pirate. The film was released by Paramount Pictures and starred Joan Fontaine, Arturo de Córdova, Basil Rathbone, Cecil Kellaway, and Nigel Bruce. Filmed in Technicolor, it was directed by Mitchell Leisen. The musical score was by Victor Young, who incorporated the main theme of French composer Claude Debussy's Clair de Lune as the love theme for the film.

The film is a mostly faithful adaptation of the novel, taking place during the reign of Charles II in the mid-17th century, mostly in the Cornish region of England.

Fontaine was under contract to independent producer to David O. Selznick, who loaned out his contract players to other studios. In this case, Fontaine was loaned to Paramount for this lavish production. She later complained about her work with director Leisen and some of her costars. The film's budget of $3.6 million made it Paramount's most expensive production up to that time.

Cast members Rathbone and Bruce were known for appearing together as Holmes and Watson, respectively, in the Sherlock Holmes films by Universal Studios. Frenchman's Creek was their only on-screen collaboration besides the Holmes films.

The film was released as an on demand DVD August 28, 2014 (Amazon); and has been shown on American Movie Classics and Turner Classic Movies.
