Casamento was an Irish-bred Thoroughbred racehorse and sire. As a two-year-old in 2010 he was one of the best colts of his generation in Ireland, finishing second in the National Stakes before winning the Beresford Stakes and the Racing Post Trophy. In the following year his only win in four starts came in the Prix du Prince d'Orange. He was retired to stud at the end of the year having won four races in three countries from eight starts.
