Ormonde (1883–1904) was an undefeated English Thoroughbred racehorse who won the 1886 English Triple Crown and was labelled the 'horse of the century' at the time. He also won the St. James's Palace Stakes, Champion Stakes and the Hardwicke Stakes twice. Ormonde was trained at Kingsclere by John Porter for the 1st Duke of Westminster. His regular jockeys were Fred Archer and Tom Cannon. After retiring from racing he suffered fertility problems, but still sired Orme, who won the Eclipse Stakes twice.

The Triple Crown of Thoroughbred Racing, often shortened to Triple Crown, is a series of horse races for Thoroughbreds, often restricted to three-year-olds. Winning all three of these Thoroughbred horse races is considered the greatest accomplishment in Thoroughbred racing. The term originated in mid-19th-century England and nations where Thoroughbred racing is popular each have their own Triple Crown series.
