Walton (1799 – December 1825) was a British Thoroughbred racehorse. He raced until he was eight years old, winning sixteen of his twenty five races. His first race was in 1802, with his first big win, the Third Class of the Oatlands Stakes, coming in 1803. He went on to win eight King's Plates and recorded wins over several leading racehorses of the time. He was owned by Sir Hedworth Williamson throughout his racing career. Walton later became a successful stallion and was champion sire of Great Britain twice. He sired the Derby winner Phantom, 2000 Guineas winner and St. Leger winner St Patrick.
