The Discovery Handicap is an American Thoroughbred horse race held annually during November at Aqueduct Racetrack in Queens, New York. A Grade III event open to three-year-old horses, it is contested on dirt over a distance of one and one eighth miles (nine furlongs).

In its 67th running in 2011, the race honors the great Discovery, the 1935 American Horse of the Year owned and raced by Alfred G. Vanderbilt II. In the list of the top 100 U.S. thoroughbred champions of the 20th Century by Blood-Horse magazine, Discovery ranks 37th.

Based at Aqueduct, the Discovery Handicap was inaugurated at Belmont Park where it was run from 1945-1958, and again in 1960-1961, 1968-1970. In one year, 1974, the race was run in two divisions. In 2005 it was contested at a distance of a mile and one sixteenth.
