Dernier Empereur (5 February 1990 – ca. 2004) was an American-bred Thoroughbred racehorse and sire. He was originally sent to race in France where he had considerable success, winning the Prix Guillaume d'Ornano and La Coupe de Maisons-Laffitte as well as finishing second in the Prix du Jockey Club as a three-year-old in 1993. In the following year he recorded his biggest success when he won the Champion Stakes in England. As a six-year-old he was transferred to the United States where he won the Del Mar Handicap and the Carleton F. Burke Handicap before his racing career was ended by injury. He made very little impact as a breeding stallion.
