Goodbye Lover is a 1998 neo-noir comedy film about a murder plot surrounding an alcoholic advertising agency worker and his adulterous wife. The film was directed by Roland Joffé, and stars Patricia Arquette, Dermot Mulroney, Don Johnson, Ellen DeGeneres and Mary-Louise Parker. The original script was written by Ron Peer; subsequent drafts were written by Robert Pucci, then Buck Henry.

The film premiered at the 1998 Cannes Film Festival, before being released theatrically in April 1999. Following its premiere, reshoots were done in Beverly Hills, and the climax was changed. This would be the last Regency Enterprises film to be released by Warner Bros. Pictures (before the former signed a distribution deal with 20th Century Fox) until the 2006 film The Fountain.
