The Pyrenean Mastiff or Mastín del Pirineo is a Spanish breed of large livestock guardian dog from the autonomous community of Aragón in north-eastern Spain. It was traditionally used to protect flocks during the annual transhumance to high summer pasture in the Pyrenees. It is a distinct and separate breed from the Spanish Mastiff or Mastin Español and from both the Pyrenean Mountain Dog and the Pyrenean Shepherd.
