54 is a 1998 American drama film written and directed by Mark Christopher. Its plot focuses on the rise and fall of Studio 54, a famous nightclub in New York City during the late 1970s and early 1980s. The film stars Ryan Phillippe, Salma Hayek, Neve Campbell, and Mike Myers.

54 was released in the United States on August 28, 1998, by Miramax. Prior to its release, the film was extensively reshot and recut, and then released to poor critical reaction but a somewhat respectable box office. In 2008, a bootleg version of the director's cut was screened at Outfest, leading to interest for its release. In 2015, Christopher and Miramax premiered a new edit of the film at the Berlin International Film Festival, with 45 minutes of original material restored and 30 minutes of studio re-shoots removed.
