Moontide is a 1942 American romantic drama with elements of a thriller. It was produced by Mark Hellinger and directed by Archie Mayo, who took over direction after the initial director Fritz Lang left the project early in the shooting schedule. The screenplay was written by John O'Hara and Nunnally Johnson (uncredited), based on the 1940 novel Moon Tide by Willard Robertson. The film features French star Jean Gabin, Ida Lupino, Thomas Mitchell and Claude Rains.

Charles G. Clarke was nominated for an Academy Award for Best Cinematography for black-and-white. Despite charismatic performances by its leads, the film was not well received on release.
