Horace A. "Jimmy" Jones (November 24, 1906 – September 2, 2001) was an American thoroughbred horse trainer. The son of Hall of Fame horse trainer Ben A. Jones, Jimmy Jones was born in Parnell, Missouri. Raised around horses from infancy, he learned how to train them from his father while working with him at Woolford Farm in Prairie Village, Kansas from 1931 to 1939, after which his father signed on as the head trainer at Calumet Farm in Lexington, Kentucky. There, Jimmy worked as his father's assistant but his career was interrupted when he joined the United States military during World War II. After the war ended he returned to training horses, and in 1948 took over as head trainer from his father, who was appointed Calumet Farm's general manager.
