A Place in the Sun is a 1951 American tragedy film based on the 1925 novel An American Tragedy by Theodore Dreiser and the 1926 play, also titled An American Tragedy. It tells the story of a working-class young man who is entangled with two women: one who works in his wealthy uncle's factory, and the other a beautiful socialite. Another adaptation of the novel had been filmed once before, as An American Tragedy, in 1931. All these works were inspired by the real-life murder of Grace Brown by Chester Gillette in 1906, which resulted in Gillette's conviction and execution by electric chair in 1908.

A Place in the Sun was directed by George Stevens from a screenplay by Harry Brown and Michael Wilson, and stars Montgomery Clift, Elizabeth Taylor, and Shelley Winters; its supporting actors included Anne Revere and Raymond Burr. Burr's performance impressed TV producer Gail Patrick, and would later lead to her casting him as Perry Mason.

The film was a critical and commercial success, winning six Academy Awards and the first-ever Golden Globe Award for Best Motion Picture – Drama. The film is sometimes considered one of the greatest American films ever made. In 1991, A Place in the Sun was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
