Reform (1964–1983) was an Irish-bred British-trained Thoroughbred racehorse and sire. In a racing career which lasted from April 1966 until October 1967 he won eleven of his fourteen races. As a two-year-old he was beaten on his debut but won his remaining six races and was rated among the best colts of his generation in Britain. Reform was never entered in the British Classic Races, but proved himself to be an outstanding three-year-old in 1967, winning five of his seven starts. After winning the St James's Stakes, St James's Palace Stakes, Sussex Stakes and Queen Elizabeth II Stakes he ended his career by beating The Derby winner Royal Palace in the Champion Stakes.
