Rule Supreme (foaled 28 February 1996) is a retired, Irish Thoroughbred racehorse who competed in National Hunt racing. During a racing career which lasted from May 2001 until December 2009 he won eleven of his forty-six races (including Grade I victories in three countries) and was placed on nineteen occasions. He showed some promise in his early career but emerged as a top-class performer in 2004 when he won the Royal & SunAlliance Chase at Cheltenham Racecourse in England and the Grande Course de Haies d'Auteuil at Auteuil Hippodrome in France. In the following year he won the Hennessy Gold Cup at Leopardstown Racecourse in Ireland. After his career in National Hunt races was ended by injury he had some success on the amateur Point-to-point circuit.
