Crotaphytus is a genus of lizards, commonly known as collared lizards, in the family Crotaphytidae. Member species are small to medium-sized predators indigenous to the American southwest, Baja peninsula, and Mexico. Including the tail, they can be as small as 7 in (18 cm) or as long as 14 in (36 cm), and are characterized by distinct bands of black or brown around the neck, to which their common names refer.
