Vow of Chastity (Italian: Voto di castità) is a 1976 Italian erotic comedy. It was directed by Joe D'Amato, who also acted as cinematographer. The story and screenplay were by George Eastman.

The film's tonal switches between light comedy and eroticism, along with serious themes such as the protagonist's Oedipus complex and a horrific dream-sequence with a splatter element, were both criticised and praised.

Voto di castità is considered noteworthy for bringing Joe D'Amato and Laura Gemser together for the first time. They soon developed a friendship and professional partnership. Gemser starred in many D'Amato films and worked for his productions as costume designer.

In an interview with the Italian film magazine Nocturno, Gemser stated that although this was a comedy, her role was more erotic than funny since she was nude most of the time, even though the situations were comedic - or at least were supposed to be.

The film was theatrically released in Italy. The French title was Voeu de chasteté, and according to Marco Giusti, the international title was Girl in a Seminary.

Voto di castità was also released on DVD in Italy by CG Entertainment in their "Cinekult" series, featuring the film in its Italian language version as an anamorphic widescreen transfer, with Italian subtitles. The DVD also included an interview with Eastman and the film in its super 8 version.

The film had previously been released on VHS by Universal-Video, Magnum 3B, and Shendene (in its series "I maestri dell'erotismo - Il cinema di Joe D'Amato").

The film is now distributed worldwide by Variety Distribution.
