Carroll House (foaled 5 March 1985) was an Irish-bred, British-trained Thoroughbred racehorse and sire. In a racing career which lasted from September 1987 until July 1990 he raced twenty times in six countries and won seven races. His most important win came in October 1989 when he won the Prix de l'Arc de Triomphe in Paris. His other wins included the Phoenix Champion Stakes, Grosser Preis von Baden, Princess of Wales's Stakes, Furstenberg Rennen and Welsh Derby. At the end of his racing career he was retired to become a breeding stallion in Japan and Ireland but had little success as a sire of winners.
