Christopher John McCarron (born March 27, 1955, Boston, Massachusetts) is a retired American thoroughbred horse racing Hall of Fame jockey. He mounted his first horse ever at 16.5 years old and was racing professionally by 18. At only 19 years old (his first year as a jockey) Chris McCarron wove a spell that brought his mounts to the winner's circle 547 times in 1974, breaking all records for most races won in a year. The previous record was set by Sandy Hawley in 1973 with 515 wins in a year.
