Chuckwallas inhabit rocky desert areas in the southwestern U.S. , especially southern Nevada to northwestern Baja, and the desert side of the southern California mountains east to central Arizona.

Chuckwallas are strictly herbivores in the wild. They're particularly fond of yellow flowers, such as those found on the brittle-bush (Encelia farinosa), and, on occasion, will climb into this plant to get to the yellow feast.
