Ruler of the World (foaled 17 March 2010) is an Irish Thoroughbred racehorse who won the Epsom Derby in 2013. He was unraced as a two-year-old. In 2013, he won a maiden race at the Curragh and the Group Three Chester Vase before winning the Derby on his third appearance. Later that year, he finished second in the Prix Niel and third in the Champion Stakes. He remained in training as a four-year-old and won the Prix Foy before being retired to stud.

Ruler of the World is a chestnut colt with a narrow white blaze bred in Ireland by Southern Bloodstock, a company associated with the Coolmore Stud. He was sired by Galileo, the winner of the 2001 Derby who went on to become an outstanding breeding stallion, winning the title of champion sire on four occasions. Galileo's other progeny include Rip Van Winkle, Nathaniel, Cape Blanco, New Approach, and Frankel.

Ruler of the World's dam, Love Me True, is a half-sister to Shuailaan (Winter Hill Stakes), Madison's Charm (Comely Stakes), and Bite The Bullet (Sanford Stakes), and, as a granddaughter of Lassie Dear, is closely related to Summer Squall, A. P. Indy, and Lemon Drop Kid. Love Me True has also produced the Cartier Champion Older Horse Duke of Marmalade.
