The Yeguada Militar de Jerez de la Frontera, known outside Spain as the Yeguada Militar, is a military Spanish stud farm headquartered in Andalusia, Spain, dedicated to horse breeding of purebred Andalusian horses and Arabian horses. Founded in 1847, it became the state military stud farm in 1893. In the 20th century, as need for cavalry horses declined, the stud's emphasis shifted to become a genetic reservoir to preserve the bloodlines of the Pure Spanish Horse and to continue to breed high quality Arabian horses, with stallions of both breeds being made available to private horse breeders to improve the horses of Spain. Today, there are two facilities located in the Jerez de la Frontera area, one primarily for stallions, the other for mares and foals, as well as multiple stallion depots across the country.
