Man of the West is a 1958 American Western film noir film starring Gary Cooper and directed by Anthony Mann, produced by Walter Mirisch and distributed by United Artists. The screenplay, written by Reginald Rose, is based on the 1955 novel The Border Jumpers, by Will C. Brown. Julie London, Lee J. Cobb, Jack Lord, and Arthur O'Connell co-star with John Dehner, Robert J. Wilke, and Royal Dano in supporting roles. The film is one of Cooper's final Westerns.

The film premiered on October 1, 1958. At the time of release, the film was largely panned by American critics, but it was praised by Jean-Luc Godard, who, before he became a director, was a film critic. Godard claimed that Man of the West was the best film of the year. Decades after the film's release, it has gained a cult following and greater acclaim, with film historian Philip French claiming the film to be Anthony Mann's masterpiece, containing Cooper's finest performance.
