Harry Thomson Jones (1925 – 5 December 2007), often known as "Tom Jones", was a British racehorse trainer whose career lasted from 1951 to 1996. He was successful in National Hunt racing, training the winners of 12 Cheltenham Festival races before switching to flat racing and going on to train the winners of British Classic Races. His last winner came when Agdistis won at Worcester Racecourse on 12 October 1996 and he retired later that year.
