A Man Called Peter is a 1955 American drama film directed by Henry Koster, and starring Richard Todd. The film is based on the life of preacher Peter Marshall, who served as Chaplain of the United States Senate and pastor of the New York Avenue Presbyterian Church in Washington, D. C., before his early death. It is adapted from the 1951 biography of the same name, written by his widow, Catherine Marshall.

The film was a box-office hit in 1955, and it was nominated for an Oscar in 1956 for its color cinematography.

This was the final feature film of the actress Jean Peters, who played Catherine Marshall. Alfred Newman reused much of his score from his 1948 film The Walls of Jericho.
