Dick Tracy (1937) is a 15-Chapter Republic movie serial starring Ralph Byrd based on the Dick Tracy comic strip by Chester Gould. It was directed by Alan James and Ray Taylor.

In this serial, Dick Tracy is a G-Man (FBI) in San Francisco rather than a Midwestern city police detective as in the comic strip. Most of the Dick Tracy supporting cast and rogues gallery were also dropped and new, original characters used instead. Dick Tracy creator Chester Gould approved the script despite these changes.
