Shadayid (10 April 1988 – April 2002) was an American-bred, British-trained Thoroughbred racehorse and broodmare. In a racing career which lasted from June 1990 to November 1991 she ran eleven times winning five races and being placed five times. Shadayid was one of the leading two-year-old fillies in Europe in 1990, winning all three of her races including the Group One Prix Marcel Boussac at the Longchamp. After winning the Fred Darling Stakes on her three-year-old debut, Shadayid took her unbeaten run to five by winning the Classic 1000 Guineas at Newmarket. Although she never won again, she finished second in the Coronation Stakes and the Sussex Stakes and third in the Haydock Sprint Cup and the Queen Elizabeth II Stakes. Shadayid was retired from racing to become a broodmare at the end of her three-year-old season after finishing seventh in the Breeders' Cup Mile.
