Jockey Club (United States)
The Jockey Club is an American organization that oversees the breed registry for Thoroughbred horses in the United States and Canada. It is dedicated to the improvement of Thoroughbred breeding and racing, and it fulfills that mandate by serving many segments of the industry through its subsidiary companies and by supporting numerous industry initiatives.
The Jockey Club was formed on February 9, 1894, and it is the keeper of the American Stud Book. It came into existence after James R. Keene spearheaded a drive for support of racehorse trainers who had complained about the Board of Control that governed racing in New York State.
