Clarence Leon Brown (May 10, 1890 – August 17, 1987) was an American film director.

After serving as a fighter pilot and flight instructor in the United States Army Air Service during World War I, Brown was given his first co-directing credit (with Tourneur) for The Great Redeemer (1920). Later that year, he directed a major portion of The Last of the Mohicans after Tourneur was injured in a fall.
