James Robert Forrest Jr. (January 24, 1920 – August 26, 1980) was an American jazz musician, who played tenor saxophone throughout his career.

Forrest is known for his first solo recording of "Night Train". It reached No. 1 on the Billboard R&B chart in March 1952, and stayed at the top for seven weeks. "Hey Mrs. Jones" (No. 3 R&B) and "Bolo Blues" were his other hits. All were made for United Records, which recorded Forrest between 1951 and 1953. He recorded frequently as both a sideman and a bandleader.
