Xaar (foaled 1995) was a British-bred Thoroughbred racehorse and sire, best known for his performances as a two-year-old in 1997. In his juvenile season Xaar won four of his five races including the Prix de Cabourg and Prix de la Salamandre in France and the Dewhurst Stakes in England. In 1998 he won the Craven Stakes on his debut, but was beaten in his remaining three races. After two further defeats in 1999 he was retired to stud where he had limited success as a sire of winners.
