Petite Etoile (foaled 1956) was a British
Thoroughbred racehorse. In a career which lasted from June 1958 until September 1961 she won fourteen of her nineteen races and finished second in the other five. After showing promising, but unexceptional form in 1958, she improved to be the British Horse of the Year in 1959, winning all six of her races including the
Classic 1000 Guineas and
Epsom Oaks. She remained in training for two further seasons, winning major races including consecutive runnings of the
Coronation Cup.
