List of North American deserts
This list of North American deserts identifies areas of the continent that receive less than 10 in (250 mm) annual precipitation. The "North American Desert" is also the term for a large U.S. Level 1 ecoregion (EPA) of the North American Cordillera, in the Deserts and xeric shrublands biome (WWF). The continent's deserts are largely between the Rocky Mountains and Sierra Madre Oriental on the east, and the rain shadow-creating Sierra Nevada, Transverse, and Peninsular Ranges on the west. The North American xeric region of over 95,751 sq mi (247,990 km2) includes: three major deserts; numerous smaller deserts; and large non-desert arid regions; in the western United States and in northeast, central, and northwest Mexico.
- The Chihuahuan Desert is the largest hot desert in North America, located in the Southwestern United States and Northern Mexico. Its total area is 140,000 sq mi (360,000 km2).
- The Sonoran Desert is a desert located in the Southwestern United States and northwest Mexico. It is the second largest hot desert in North America. Its total area is 120,000 sq mi (310,000 km2).
- The Mojave Desert is the hottest desert in North America, located primarily in southeastern California. Its total area is 22,000 sq mi (57,000 km2).

Western arid regions of North America
The separately defined western arid regions of North America are continental regions of aridity based on available water in addition to rain shadow-diminished rainfall and which have many non-desert shrub-steppe (EPA) and xeric shrublands (WWF) in addition to desert ecosystems and ecoregions. This large arid region of 190,000 sq mi (490,000 km2) includes: deserts, such as the Great Basin Desert and Sonoran Desert; and the non-desert arid region areas (with greater than 10 inches (250 mm) annual precipitation) in the Great Basin arid region, Colorado Plateau, Mexican Plateau, and others. This arid region extends from the top of the North American Desert in Washington and Idaho southward into Mexico in the Trans-Mexican Volcanic Belt. The 'western arid region' is east of and (except for Mojave sky islands) discontiguous from the Mojave Desert, unlike the southwestern Great Basin deserts adjacent with ecotones to the northern Mojave Desert.
