The Calgary Underground Film Festival (CUFF) is a film festival held annually in Calgary, Alberta, Canada, for eleven days at the downtown Globe Cinema.[1] Founded in 2003, Calgary Underground Film Festival is a not-for-profit organization screening films that defy convention.

CUFF currently has two annual festivals. The main Calgary Underground Film Festival runs for seven days in mid-April, while the CUFF.Docs International Documentary Festival is in November. They also showcase special event screenings throughout the year.

CUFF introduces audiences to the people behind the lens by showcasing local and international indie filmmakers. It showcases a roster of films rarely seen in North American theatres, screening contemporary works in various categories (feature, documentary, animation, and shorts), and all genres (horror, sci-fi, fantasy, comedies, thrillers, and music-related films).

This years festival runs from April 17-27, 2025 and features genre films from across the globe as well as festival fan favourite The 48 Hour Film Making Challenge.

All registered teams were provided randomly selected elements – genre, prop and line of dialogue – to include in their film. The teams were given just 48 hours to complete a 2 to 5 minute short film, which will be screened for the first time before an audience on the big screen! The in-competition shorts, which meet all the rules of the challenge, will be juried live at the screening, followed by an awards ceremony. The films will receive jury and audience awards based on how well teams integrated the given elements and the overall quality of film produced, including story, structure, and entertainment factor. One of the most celebrated, fun and must-attend events at CUFF!

The 22nd Calgary Underground Film Festival is an in-cinema only festival, with all films playing at Globe Cinema from April 17-27, 2025.
