Joseph A. Notter (June 21, 1890 - April 10, 1973) was an American Hall of Fame Champion jockey and winner of two of the American Classic Races. A native of Brooklyn, New York, Joe Notter rode prominently in the first decades of the 20th century. Statistics from his racing career as a jockey are limited but it is known that he was working as a stable boy at age ten and was riding and winning at age thirteen. He developed a reputation as a good handler of young horses and rode winners in several important stakes races for two-year-old horses including three wins in the important Hopeful Stakes.
