The Locarno Film Festival is a major international film festival, held annually in Locarno, Switzerland. Founded in 1946, the festival screens films in various competitive and non-competitive sections, including feature-length narrative, documentary, short, avant-garde, and retrospective programs. The Piazza Grande section is held in an open-air venue that seats 8,000 spectators.

A film festival is an organized, extended presentation of films in one or more cinemas or screening venues, usually in a single city or region. Increasingly, film festivals show some films outdoors. Films may be of recent date and depending upon the festival's focus, can include International and Domestic releases. Some film festivals focus on a specific filmmaker, genre of film, or subject matter. Several film festivals focus solely on presenting short films of a defined maximum length. Film festivals are typically annual events. Some film historians, including Jerry Beck, do not consider film festivals as official releases of the film.
