Antonio (1816–1828) was a British Thoroughbred racehorse and sire best known for winning a controversial race for the classic St Leger Stakes in 1819. The classic was run twice after claims of an irregular start but Antonio’s victory in the original running was eventually allowed to stand. The rest of his racing career which lasted from April 1819 until May 1822 was relatively undistinguished although he won five other races.
