Payback is a 1999 American neo-noir action thriller film written and directed by Brian Helgeland in his directorial debut, and starring Mel Gibson, Gregg Henry, Maria Bello, Lucy Liu, Deborah Kara Unger, David Paymer and James Coburn. It is based on the novel The Hunter by Donald E. Westlake using the pseudonym Richard Stark, which had earlier been adapted into the 1967 film Point Blank.

During post-production, Helgeland was removed by Gibson and the producers, who rewrote and reshot substantial portions of the film, including a different third act and a new villain played by Kris Kristofferson. This version of the film was released by Paramount Pictures on February 5, 1999, and received mixed reviews from critics.

In 2006, Helgeland issued a director's cut, entitled Payback: Straight Up, that differs substantially from the version released by the studio. This new version received a more positive reception, and is generally considered superior to the theatrical cut.
