Rising Fast (foaled 1949) was an outstanding New Zealand-bred Thoroughbred racehorse. In 1954 he became the only horse in history to win the Melbourne Cup, Caulfield Cup and Cox Plate races in the same season - the Spring Grand Slam - and since that time no Melbourne Cup winner has performed such a feat. He returned in 1955, again winning the Caulfield Cup but coming an unlucky second in the Melbourne Cup.
