"Jim" Ryan (August 30, 1900 - July 26, 1976) was an American Thoroughbred horse racing trainer in both steeplechase and flat racing. A native of Ireland, his father, Owen J. Ryan, was the master of Cleaboy Stud in Mullingar, County Westmeath, Ireland. While working in a factory in England in his early teens, Jim Ryan began riding steeplechase horses on weekends. He eventually made it a career and after moving to the United States in the 1930s, became a trainer and breeder.
