Eurythmic (1916–1925) was a versatile Australian-bred Thoroughbred racehorse who had the ability to produce a brilliant finishing run in staying races and he also won important sprint races, too. At four he won 12 of his 13 starts including the Caulfield Cup and Sydney Cup. When Eurythmic finished racing he was the greatest stake-winner in Australia. He was later inducted into the Australian Racing Hall of Fame.

The Caulfield Cup is a Melbourne Racing Club Group 1 Thoroughbred horse race held under handicap conditions. This is for all horses aged three years old and older. It takes place over a distance of 2400 metres at the Caulfield Racecourse, Melbourne, Australia in mid October. The prize money is A$5,000,000.
