The Knickerbocker Stakes is an American Grade III race on turf for Thoroughbred horses run each year at Belmont Park in Elmont, New York.
The Knickerbocker is open to three-year-olds and up, and set at a distance of 1+1⁄8 miles (nine furlongs).
The race was originally run as the Knickerbocker Handicap at Aqueduct Racetrack in late October or early November, although the 1962, 1995 and 2001 renewals were held at Belmont.
The race was permanently moved to Belmont Park in 2008 and was changed from a handicap to allowance weight conditions in 2009.
In 1977, 1992, 1997 and 2023 the race was switched from turf to dirt due to rain.
