Les Biches (English: The Does) is a 1968 drama film directed by Claude Chabrol. It depicts a tortured love triangle between characters portrayed by Stéphane Audran and Jacqueline Sassard; Jean-Louis Trintignant also stars. Audran won the Silver Bear for Best Actress at the 18th Berlin International Film Festival. The film had a total of 627,164 admissions in France.

While the film does not acknowledge any literary sources, Les Biches is loosely based on Patricia Highsmith's 1955 novel The Talented Mr. Ripley, with the main characters' genders being switched. Chabrol's screenwriter Paul Gégauff had previously adapted the novel into Purple Noon in 1960.
