The Nashua Stakes is an American Thoroughbred horse race held either at Aqueduct Racetrack or Belmont Park, New York. Named for Nashua, the 1955 United States Horse of the Year, it was first run in 1975. A Grade II race, it is open to two-year-olds and has been raced over a distance of one mile since 1994. Held in late October, it currently offers a $100,000-added purse.
The race returned to Grade II status in 2009 when the American Graded Stakes Committee upgraded it from Grade III. In 2001, the race was run at Belmont Park. The distance was set at a mile and 70 yards for 1985, at a mile and a sixteenth from 1987 to 1993. The race was not run in 1995.
