El Gran Senor (21 April 1981 – October 2006) was an American-bred Thoroughbred race horse, foaled at Windfields Farm in Maryland. He was the best horse of his generation in Europe at both two and three years of age, ahead of an outstanding group of contemporaries which included Chief Singer, Darshaan, Rainbow Quest, Sadler's Wells, Lashkari, Pebbles, Commanche Run and Northern Trick. His only defeat in eight races came when he was beaten a short head by Secreto in the 1984 Epsom Derby.
