Le Moss (3 April 1975 – 17 August 2000) was a British Thoroughbred racehorse and sire. A specialist stayer, he excelled at distances of two miles and beyond, winning eleven times from fifteen races between 1977 and 1980. He showed good form as a three-year-old, winning the Queen's Vase and finishing second in the classic St Leger Stakes, but reached his peak as an older horse. In 1979 he completed the "Stayers' Triple Crown" by winning the Ascot Gold Cup, Goodwood Cup and Doncaster Cup.
