James Theodore Combest (June 24, 1926 – January 8, 2013) was a jockey and trainer in American Thoroughbred racing.
Triple Crown series, Combest and Roman Line finished third to winner Greek Money and runner-up Ridan.
The first of Combest's two mounts in the Preakness Stakes had come in 1958 when he rode Noureddin to a fifth-place finish behind runner-up Lincoln Road and Calumet Farm's winner and future Hall of Fame inductee Tim Tam.
Later in June, Jimmy Combest made his only appearance in the Belmont Stakes, riding Royal Bay Gem to third place behind Tim Tam and the Irish horse Cavan.
As a trainer, Combest met with modest success and would retire from racing to manage a Florida horse farm.
