Man on Fire is a 2004 American vigilante action thriller film directed and produced by Tony Scott, with a screenplay by Brian Helgeland and co-produced by Arnon Milchan. It is based on the 1980 novel of the same name by A. J. Quinnell. The film stars Denzel Washington and Dakota Fanning in lead roles, alongside Christopher Walken, Radha Mitchell, Giancarlo Giannini, Marc Anthony, Rachel Ticotin and Mickey Rourke in supporting roles. This adaptation shifts the setting from Naples, Italy, to Mexico City, diverging from the earlier 1987 film version of Quinnell's novel, which was also produced by Milchan.

The film follows a despondent, alcoholic former CIA officer-turned-bodyguard, who embarks on a violent revenge spree after a nine-year-old under his charge is kidnapped in Mexico City.

Man on Fire was released in the United States by 20th Century Fox on April 23, 2004. The film received mixed reviews from critics, with praise for Washington's performance and the film's intense action sequences; however, it was criticized for its graphic violence and pacing. It emerged as a commercial success at the box-office, grossing $130 million worldwide against a production budget of $60–70 million. Fanning's performances earned her nominations for the Critics' Choice Movie Award for Best Young Performer and the Young Artist Award for Best Leading Young Actress in a Feature Film. Additionally, the film received 2 nominations at the 36th NAACP Image Awards – Outstanding Motion Picture and Outstanding Actor in a Motion Picture (Washington).
