Hyperion (18 April 1930 – 9 December 1960) was a British-bred Thoroughbred, a dual classic winner and an outstanding sire. 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 St Leger Stakes. He was the most successful British-bred sire of the 20th century and champion sire in Great Britain six times between 1940 and 1954.
