Glenstal (6 April 1980 – 6 October 2007) was an American-bred, Irish-trained Thoroughbred racehorse and sire. In a brief racing career which lasted from July 1982 until July 1983 he won three of his five races. After winning on his first appearance he won the National Stakes on his second and final start of the year. In 1983 he finished second on his seasonal debut and rebounded from a poor run at Royal Ascot to win the Prix Daphnis. He stood as a breeding stallion in Ireland, Hungary and the Czech Republic and had some success as a sire of winners before dying in 2007 at the age of twenty-seven.
