Jacola (1935–1959) was an American Champion Thoroughbred racehorse. Bred by Arthur B. Hancock, she was sired by the British import Jacopo, a son of the 1924 Epsom Derby winner, Sansovino. Jacola was out of the mare La France, a daughter of Sir Gallahad, who was the leading sire in North America in 1930, 1933, 1934, and 1940 and who sired 1930 U.S. Triple Crown winner Gallant Fox. A year following Jacola's birth, La France foaled U.S. Racing Hall of Fame inductee Johnstown, winner of the 1939 Kentucky Derby and Belmont Stakes.
