John Joseph Bejshak (September 19, 1909 – December 26, 1969) was a Canadian-born jockey who competed in American Thoroughbred horse racing best known as the rider of 1935 American Horse of the Year, Discovery. Plagued by weight gain, Bejshak's career was cut short. He retired from riding in 1936 and in the 1940s went to work for Laurel Park as custodian of the jockey quarters, patrol judge, clerk of scales, and placing judge. He died of a heart attack in 1969 at age sixty.
