Bilitis is a 1977 French romantic and erotic 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.^[1]

Bilitis, a teenage schoolgirl, spends the summer with her aunt Melissa and her unfaithful husband Pierre, a couple whose marriage is strained, and develops a lesbian crush on Melissa. Meanwhile, she pursues Lucas, a local teenage boy, and tries to find a "suitable male lover" for Melissa.^[2]

Bilitis' sexual adventure eventually lead to an unhappy result, and she decides to return to school alone.
