Carroll Hugh "Cal" Shilling (1885–1950) was an American Thoroughbred horse racing Hall of Fame jockey. In his 1926 autobiography, The Spell of the Turf, Hall of Fame trainer Sam Hildreth wrote that Shilling was the greatest rider he ever saw.
A native of Texas, Carroll Shilling was frequently referred to as "Cal". He began riding at an early age on bush tracks in the Southwestern United States and embarked on a professional riding career in 1904. The following year he moved to compete at racetracks in the New York and New Jersey areas. In 1910, he was the United States Champion Jockey by earnings. Shilling also would ride in Canada for the prominent stable owned by liquor magnate Joseph E. Seagram, winning a number of important races including what became one of the Canadian Classic Races, the Breeders' Stakes.
