Prince Leopold (horse)
 Prince Leopold (1813–1817) was a British Thoroughbred racehorse and winner of the 1816 Epsom Derby. Prince Leopold was bred by the Duke of York and raced as a three and four-year-old. The bay colt had an unruly temperament and was castrated at the end of the 1817 racing season in an attempt to improve his behavior but he died shortly after the procedure.
