A.P. Indy was an American Thoroughbred racehorse who won the Belmont Stakes and Breeders' Cup Classic on his way to American Horse of the Year honors in 1992. His time in the Belmont Stakes tied Easy Goer for the second-fastest running in the history of the race, behind his damsire Secretariat.

The Belmont Stakes is an American Grade I stakes race for three-year-old Thoroughbreds run at Belmont Park in Elmont, New York. It is run over the worldwide classic distance of 1+1⁄2 miles. Colts and geldings carry a weight of 126 pounds (57 kg); fillies carry 121 pounds (55 kg). The race, nicknamed The Test of the Champion, The Test of Champions and The Run for the Carnations, is the traditional third and final leg of the Triple Crown. It is usually held on the first or second Saturday in June, five weeks after the Kentucky Derby and three weeks after the Preakness Stakes. The 1973 Belmont Stakes and Triple Crown winner Secretariat holds the track record of 2:24.
