Indiana (1961–14 June 1983) was an Irish-bred, British-trained Thoroughbred racehorse and sire. In a career which lasted from autumn 1963 until July 1965 he ran thirteen times and won four races. He won the Classic St Leger as a three-year-old in 1964, the same year in which he also won the Chester Vase and the Great Voltigeur Stakes. Indiana also finished second in The Derby and the Grand Prix de Paris. He retired from racing and was exported in 1966 to stand as a stallion in Japan. He died in 1983.
