Mohave County is located in the northwestern corner of the U.S. state of Arizona. As of the 2010 census, its population was 200,186. The county seat is Kingman.[1] While the largest single city is Lake Havasu City, the area with highest population is the Bullhead City/Fort Mohave/Mohave Valley area.[2]

Mohave County contains parts of Grand Canyon National Park and Lake Mead National Recreation Area and all of the Grand Canyon-Parashant National Monument. The Kaibab, Fort Mojave and Hualapai Indian Reservations also lie within the county.

Mohave County is the fifth-largest county in the United States by land area.


Mohave County was the one of four original Arizona Counties created by the 1st Arizona Territorial Legislature. The county territory was originally defined as being west of longitude 113° 20' and north of the Bill Williams River.[3] Pah-Ute County was created from it in 1865 and was merged back into Mohave County in 1871 when much of its territory was ceded to Nevada in 1866. The county's present boundaries were established in 1881.


According to the 2000 census, the county has a total area of 13,469.71 square miles (34,886.4 km2), of which 13,311.64 square miles (34,477.0 km2) (or 98.83%) is land and 158.07 square miles (409.4 km2) (or 1.17%) is water.[4] The county is the fifth largest U.S. county in area (excluding boroughs and census areas in Alaska), exceeded in size only by adjacent San Bernardino County, California (20,053 square miles), adjacent Coconino County (18,617 square miles), and the Nevada counties of Nye (18,147 square miles) and Elko (17,179 square miles).

The county consists of two sections divided by the Grand Canyon, with no direct land communication between them. The northern section, smaller and less populated, forms the western part of the Arizona Strip, bordering Utah and Nevada. The larger southern section, borders Nevada and California across the Colorado River, which forms most of the county's western boundary. The southern section includes Kingman, the county seat, and other cities, as well as part of the Mojave Desert.

Adjacent counties[edit]

Mohave County and its adjacent counties form the largest such block of counties outside of Alaska. Their combined land area is 89,567.34 square miles (231,978.3 km2), or larger than that of the state of Idaho. They include the #1 (San Bernardino), #2 (Coconino), #5 (Mohave), and #7 (Lincoln) largest counties outside of Alaska.

National protected areas[edit]

There are 18 official wilderness areas in Mohave County that are part of the National Wilderness Preservation System. Most of these are managed by the Bureau of Land Management, but some are integral parts of the preceding protected areas, or have shared jurisdiction with the BLM. Some extend into neighboring counties (as indicated below) All wilderness areas within Grand Canyon-Parashant NM are managed by BLM, although the National Monument as a whole shares management with the National Park Service:
