Powerscourt (1 April 2000 – 17 July 2021) was a British-bred Irish-trained Thoroughbred racehorse and sire, best known for his two runs in the Arlington Million: he was disqualified after finishing first in 2004 but returned to win the race in the following year.
He raced in Ireland, Britain, Germany, the United States, Japan, Hong Kong and the United Arab Emirates in four seasons of racing, winning five of his twenty-one starts. His other major wins came in the Great Voltigeur Stakes at three and the Tattersalls Gold Cup at four. In addition to his wins he was placed in several major races including the Racing Post Trophy, Irish St. Leger, Prince of Wales's Stakes, Bayerisches Zuchtrennen, Irish Champion Stakes and Breeders' Cup Turf.
After his retirement from racing he stood as a breeding stallion in the United States and Turkey.
