St. Gatien (1881–after 1906) was a British Thoroughbred racehorse and sire. In 1884 he was involved in the second and final dead heat in the history of The Derby, part of an unbeaten sequence of twelve races. St. Gatien went on to become a dominant performer in long-distance races, winning the Gold Cup and the Alexandra Plate at Royal Ascot, the Cesarewitch Handicap carrying a record weight, and three successive running of the Jockey Club Cup.
In a racing career which lasted from 1883 until October 1886 he ran nineteen times, won sixteen races and was never beaten at level weights. He was regarded by contemporary experts as one of the greatest horses of the 19th century. At the end of the 1886 season he was retired to stud where he had success in England, Germany and the United States.
