Teddington (1848–1866) was a British Thoroughbred racehorse and sire. In a career that lasted from April 1850 to October 1853 he ran eighteen times and won ten races. Teddington won important races in each of his four seasons, most notably the Derby in 1851. In the next two years he proved himself to be a formidable stayer who excelled at distances in excess of two miles, winning the Doncaster Cup in 1852 and the Emperor of Russia's Plate in 1853. He was regarded by British experts as one of the best racehorses of his era. Teddington was retired to stud at the end of the 1853 season where he had limited success before being exported to Hungary in 1862.
