Gato Del Sol (February 23, 1979 – August 7, 2007) was an American Thoroughbred racehorse. He was foaled at Stone Farm in Paris, Kentucky, the son of U.S. Racing Hall of Fame inductee Cougar II and the mare Peacefully, whose grandsire was Bold Ruler, another Hall of Fame champion and an eight-time Leading sire in North America. Gato Del Sol was owned and bred by Stone Farm proprietor Arthur B. Hancock III in partnership with one of his longtime clients, Manhattan real estate broker Leone J. Peters. The two men also bred Risen Star, winner of the 1988 Preakness and Belmont Stakes.
