Hyperion (18 April 1930 – 9 December 1960) was a British-bred Thoroughbred racehorse, a dual classic winner, an outstanding sire, and considered to be one of the most important Thoroughbreds of the 20th century.
Owned by Edward Stanley, 17th Earl of Derby, Hyperion won GBP £29,509 during his racing career—a considerable sum at the time. His victories included the Epsom Derby and the St. Leger Stakes. He was the most successful British-bred sire of the 20th century and the champion sire in the UK six times between 1940 and 1954.

History
Hyperion was born on 18 April 1930. His thoroughbred sire was Gainsborough, who was one of three wartime Triple Crown winners in the United Kingdom. His dam was Selene, her sire was Chaucer, the son of St. Simon. Selene was the dam of sires such as Sickle (GB) (sireline ancestor of Native Dancer and Sea Bird), Pharamond (US), and Hunter's Moon (GB). Hyperion was linebred 3x4 to St. Simon.
The colt was bred and owned by Edward Stanley, 17th Earl of Derby, who hired George Lambton to train him.
According to writer Avalyn Hunter on Hyperion's conformation: "[Hyperion was a] muscular, powerfully built chestnut horse...he was short-legged and long-bodied for his height [15.1 hands (61 inches, 155 cm)], and somewhat ewe-necked and straight-shouldered, but had excellent action. He was light-boned below the knee. Although he had a distinct personality, and could have a mind of his own, he had a calm disposition. He was a thoroughly lazy horse at work, which was unfortunate as he needed a good deal of training to get into top condition, but was a determined performer on the race course."
