Maîtresse (English: "mistress" or "teacher") is a 1975 French sex comedy film co-written and directed by Barbet Schroeder, starring Bulle Ogier and, in one of his earliest leading roles, Gérard Depardieu.

Ariane, an attractive young woman in her dressing gown asks them in to help, as the bath she was running has overflowed.

Olivier becomes her live-in lover, thinking he will be the strong man for a vulnerable woman, but she is older, tougher, and a lot wiser.

Examiners' reports agreed that the film was well made and not exploitative, but under their censorship standards of the time it had to be refused a certificate: "the actual scenes of fetishism are miles in excess of anything we have ever passed in this field".

However, in 1980, the film was subsequently re-examined for public release by the BBFC, and in February 1981 was granted an 'X' certificate in a cut version.
