Juarez is a 1939 American historical drama film directed by William Dieterle. The screenplay by Aeneas MacKenzie, John Huston, and Wolfgang Reinhardt is based on the 1934 biography The Phantom Crown by Bertita Harding and the 1925 play Juarez and Maximilian by Franz Werfel.

William Dieterle was a German-born actor and film director who emigrated to the United States in 1930 to leave a worsening political situation. He worked in Hollywood primarily as a director for much of his career, becoming a United States citizen in 1937. He moved back to Germany in the late 1950s.
