The National Stallion Stakes was an American Thoroughbred horse race held sixty-two times between 1898 and 1971. Inaugurated as the National Stallion Race at Morris Park Racecourse in Westchester County, New York, the event was open to horses of either sex until 1948 when it became a race exclusively for colts and geldings and a National Stallion Stakes (filly division) was created. Contested on dirt at a distance of five furlongs, from 1905 onward it was hosted by Belmont Park in Elmont, New York except for 1963 through 1967 when it was run at Aqueduct Racetrack in South Ozone Park, Queens, New York.
