Mademoiselle is a 1966 psychological thriller film directed by Tony Richardson. Jeanne Moreau plays the title character, a seemingly-respectable schoolteacher in a small French village, who is actually an undetected sociopath.

A British and French co-production, the film was nominated for the Palme d’Or at the 1966 Cannes Film Festival, and was released theatrically in France on 3 June 1966. It won a BAFTA Award for Best Costume Design (for Jocelyn Rickards).
