The Iberian horse is a designation given to a number of horse breeds native to the Iberian Peninsula. At present, some breeds are officially recognized by the FAO,[1][2] while other horses believed to be native to the peninsula are not. Likewise, some modern breeds are understood from mitochondrial DNA to be descended from historic landraces, while others have origins outside the Iberian peninsula.[3][4] The remaining FAO-recognized breeds are of well-known foreign blood, or are recently developed breeds.
