The Eclipse Stakes was an American Thorougbred race for two-year-old horses of either sex. Inaugurated August 24, 1889 at New York's Morris Park Racecourse with a then substantial purse of $28,000, from inception through 1894 the race was known as the Great Eclipse Stakes. Initially run at a distance of 6 furlongs, in 1897 the race was reduced to 5 1/2 furlongs. The Morris Park facility did not reopen after its 1904 racing season and in 1905 the event was taken up by the owners of the new Belmont Park racing facility in Elmont, New York where it would be run annually through 1907.
