Hawaiian Sound (foaled 7 April 1975) was an American-bred, British-trained Thoroughbred racehorse and sire. In a fifteen-race career he won five times, including the Group One Benson and Hedges Gold Cup in 1978. The horse was also placed in several other top-class races – Royal Lodge Stakes, Chester Vase, the Derby, Irish Derby, King George VI and Queen Elizabeth Stakes and Champion Stakes. His later career was compromised by illness and he was not a success at stud.
