The Postman is a 1997 American epic post-apocalyptic adventure film produced and directed by Kevin Costner, who plays the lead role. The screenplay was written by Eric Roth and Brian Helgeland, based on David Brin's 1985 book of the same name. The film also features Will Patton, Larenz Tate, Olivia Williams, James Russo, and Tom Petty.

It is set in a post-apocalyptic and neo-Western version of the disestablished United States in the then near-future year of 2013, 16-plus years after unspecified apocalyptic events, followed by plagues, left a huge impact on human civilization and erased most technology. Like the book, the film follows the story of a nomadic drifter (Costner) who stumbles across the uniform of a United States Postal Service mail carrier, and unwittingly inspires hope through an empty promise of a "Restored United States of America" and starts his path to become a national hero.

Released on Christmas 1997 by Warner Bros., The Postman was panned by critics, who criticized the performances, screenplay, direction, and long runtime. Costner's decision to cast himself in the film was criticized. The film was a box-office bomb, grossing a total of $20.8 million worldwide against a budget of $80 million. It was nominated for three Saturn Awards and won all five of its Golden Raspberry Award nominations, including Worst Picture.
