Bilitis is a 1977 French erotic romantic drama film directed by photographer David Hamilton, with a music score by Francis Lai. It stars Patti D'Arbanville and Mona Kristensen as the title character Bilitis and Melissa, respectively.

The film is loosely based on a poem cycle by Pierre Louÿs entitled The Songs of Bilitis set in ancient Greece, although the film is set in modern Europe. The poems were meant to be autobiographical works by the title character.
