Noble Decree (foaled 6 March 1970) was an American-bred British-trained Thoroughbred racehorse and sire. As a two-year-old colt he won two of his first five races before ending his season with a win in the Observer Gold Cup. He was rated the best colt of his generation in the 1972 Free Handicap. In the following year he was narrowly beaten by Mon Fils in the 2000 Guineas before suffering a career-ending injury in the Epsom Derby. He had no success as a breeding stallion.
