Mango (foaled 1834) was a British Thoroughbred racehorse and sire best known for winning the classic St Leger Stakes in 1837. He won nine of his thirteen races in a racing career which lasted from October 1836 until October 1838. Mango was well-beaten in his only race as a two-year-old and finished unplaced in the Epsom Derby but won three races at Royal Ascot in June.
