Authaal (17 May 1983 – after 1999) was an American-bred Thoroughbred racehorse and sire. He was probably the best horse sired by the ill-fated Shergar,[2] winning at the highest level in both Ireland and Australia. He was unraced as a two-year-old but won four of his five races as a three-year-old in 1986, culminating in an emphatic victory in the Irish St. Leger. After failing to reproduce his best form in 1987, he was set to race in Australia where he recorded major wins in the Queen Elizabeth Stakes and Underwood Stakes. After his retirement from racing he stood as a breeding stallion in Japan but had little success as a sire of winners.
