James Homer "Casey" Hayes (June 16, 1906 - June 25, 1980) was an American Thoroughbred racehorse trainer whose horses won eight national Championship titles of which two were inducted in the National Museum of Racing and Hall of Fame.
A native of Brevard, North Carolina, after working with show hunters and polo ponies, Hayes greatest success came during the twenty-six years between 1943 and 1969 when he trained Thoroughbreds for flat racing for Christopher Chenery.
