American Quarter Pony (AQP) is any horse with the conformation of an American Quarter Horse, and whose height is 14.2hh or less.

About:
The breed was officially recognized in 1964, when the American Quarter Pony Association was formed. Because of its small size and comfortable temperament, the AQP mostly serves as a versatile mount for children, and can be seen in both Western and English riding disciplines.

Breeding:
Unlike their name suggests, AQPs don't need to have American Quarter parents. In fact, they can have mixed or "unknown" parentage (which means they can be non-purebred), and still be eligible for registration, as long as they have the conformation of a Quarter Horse and are not gaited. Therefore, AQPs are not necessarily "small Quarter Horses," but are rather a completely different breed.
