The San Esteban chuckwalla (Sauromalus varius), also known as the piebald chuckwalla or pinto chuckwalla, is a species of chuckwalla belonging to the family Iguanidae endemic to San Esteban Island in the Gulf of California. It is the largest of the five species of chuckwallas and the most endangered.

The San Esteban chuckwalla is the largest species of chuckwalla, reaching 61 cm (24 in) in body length and 76 cm (30 in) overall length, and weighing up to 1.4 kg (3.1 lb).[3] It is considered a textbook example of island gigantism, as it is three to four times the size of its mainland counterparts.[3] The male's skin is gray with tan to yellow patches over its entire body, and its face is gray to black. The female is duller in appearance with fewer patches. The colorations provide almost perfect camouflage against some of their predators.
