Ramón A. Domínguez (born November 24, 1976) is a retired Venezuelan jockey and Hall of Fame member in American thoroughbred horse racing.

He emigrated to the United States where he began riding at Florida's Hialeah Park Race Track in 1996.

He repeated the feat in 2003, and in 2004 he won the Isaac Murphy Award for having the highest winning percentage among all American-based jockeys.

In 2012 Dominguez topped the New York Racing Association (NYRA) riding circuit for the fourth straight year with 322 victories, and was also the winner of the George Woolf Memorial Jockey Award, bestowed by his peers for excellent conduct and given by Santa Anita Park.

On June 13, 2013, Dominguez announced his retirement following the advice of his doctors after a traumatic brain injury he sustained at Aqueduct Racetrack on January 18, 2013.
