James Joseph “Buster“ Bennett (March 19, 1914 – July 3, 1980) was an American blues saxophonist and blues shouter. His nickname was “Leap Frog”. At various times in his career, he played the soprano saxophone, the alto, and the tenor. He was known for his gutbucket style on the saxophone. He also played the piano and the string bass professionally.

Bennett was born in Pensacola, Florida. By 1930 or so, he was working in Texas, but he spent most of his active career (1938 to 1954) in Chicago. He was employed as a session musician by Lester Melrose from 1938 to 1942; he played on recordings with Big Bill Broonzy, the Yas Yas Girl, Monkey Joe, and Washboard Sam. Concomitantly he played on sessions with Jimmie Gordon under the direction of Sammy Price.
