The Mexican Plateau horned lizard (Phrynosoma orbiculare) is a species of horned lizard in the family Phrynosomatidae. The species, also known commonly as the Chihuahua Desert horned lizard, is endemic to Mexico. There are five recognized subspecies. The specific epithet, orbiculare, comes from the Latin adjective orbis, meaning "circular".
