Jockey Club (United States)

The Jockey Club is the breed registry for Thoroughbred horses in the United States and Canada. It is dedicated to the improvement of Thoroughbred breeding and racing and fulfills that mandate by serving many segments of the industry through its subsidiary companies and by supporting numerous industry initiatives.

The Jockey Club, formed on February 9, 1894, 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.
