Bad Santa is a 2003 American screwball black comedy film directed and co-written by Terry Zwigoff, produced by the Coen brothers, and starring Billy Bob Thornton as the title character and Tony Cox as his partner in crime. Actors Bernie Mac and John Ritter (in his final live-action film) co-star. Lauren Graham, Lauren Tom, Ethan Phillips, Brett Kelly, and Cloris Leachman are also featured.

The unrated version of the film was released on DVD on March 5, 2004 and on high-definition Blu-ray Disc (November 20, 2007) as Badder Santa. A director's cut DVD was released in November 2006. It features Zwigoff's cut of the film (including an audio commentary with him and the film's editor), but is three minutes shorter than the theatrical cut and ten minutes shorter than the unrated version. The film was screened out of competition at the 2004 Cannes Film Festival.
