Turtle Island (foaled 16 March 1991) was an Irish-bred, British-trained Thoroughbred racehorse and sire. He was one of the leading British two-year-olds of 1993 when he won four of his seven races including the Norfolk Stakes, Phoenix Stakes and Gimcrack Stakes. In the following year he won the Greenham Stakes before winning the Irish 2000 Guineas by fifteen lengths. He was beaten in his three remaining races and was retired to stud, where he had some success as a sire of winners.
