Lee Orville Erwin (July 15, 1908 – September 21, 2000) was an American theatre organist who played an important part in a revival of interest in the silent film era. His career began as an organist accompanying first-run silent films in the 1920s. He received classical training in Cincinnati and France, and then began a career as organist and arranger for radio, significantly at WLW and CBS Radio, the latter in association with Arthur Godfrey, that lasted through the mid-1960s. When his radio career ended he was commissioned to provide complete new scores for silent films exceeding seventy in number, and in this capacity and as an organist for silent film tours and exhibitions he received widespread critical acclaim. Erwin was active into his early 90s.
