Coconino County is a county in the North-Central part of the U.S. state of Arizona. Its population was 145,101 at the 2020 census.^[1] The county seat is Flagstaff.^[2] The county takes its name from Cohonino,^[3] a name applied to the Havasupai people. It is the second-largest county by area in the contiguous United States, behind San Bernardino County, California. It has 18,661 sq mi (48,300 km²), or 16.4% of Arizona's total area, and is larger than the nine smallest states in the U.S.

Coconino County comprises the Flagstaff metropolitan statistical area, Grand Canyon National Park, the federally recognized Havasupai Nation, and parts of the federally recognized Navajo, Hualapai, and Hopi nations. As a result, its relatively large Native American population makes up nearly 30% of the county's total population; it is mostly Navajo, with smaller numbers of other tribes.

The county was the setting for George Herriman's early 20th-century Krazy Kat comic strip.

After European Americans completed the Atlantic & Pacific Railroad in 1883, the region of northern Yavapai County began to undergo rapid growth. The people of the northern reaches had tired of the rigors of traveling to Prescott to conduct county business. They believed that they should have their own county jurisdiction, so petitioned in 1887 for secession from Yavapai and creation of a new Frisco County. This did not take place, but Coconino County was formed in 1891 and its seat was designated as Flagstaff.

According to the United States Census Bureau, the county has a total area of 18,661 square miles (48,330 km²), of which 18,619 square miles (48,220 km²) are land and 43 square miles (110 km²) (0.2%) are covered by water.^[4] It is the largest county by area in Arizona and the second-largest county in the United States (excluding boroughs in Alaska) after San Bernardino County in California. It has more land area than each of the following states: Connecticut, Delaware, Hawaii, Maryland, Massachusetts, New Hampshire, New Jersey, Rhode Island, and Vermont.

The highest natural point in the county, as well as the entire state, is Humphreys Peak at 12,637 ft or 3,852 m. The Barringer Meteor Crater is located in Coconino County.
