The Fort Marcy Handicap is an American Thoroughbred horse race run occasionally at Belmont Park in Elmont, New York. A Grade III race, it is open to horses three-years-old and up and is raced on turf over a distance of 1 1/16 miles. The event currently offers a purse of $100,000 added. The race is named for the U.S. Racing Hall of Fame horse, Fort Marcy.

Inaugurated in 1975 at a distance of seven furlongs, it was run in two divisions that year as well as in 1978, 1981, and 1987. There was no race held in 1976 and 1977. In 1980, the Fort Marcy Handicap was restricted to horses, age four and older. The event was hosted by Belmont Park in 1981, 1987, 1988 and 2009. In 1998 and 2003, bad weather resulted in the race being contested on the dirt track at a distance of one mile (8 furlongs).
