Coconino County is a county located in the north central part of the U.S. state of Arizona. It is part of the Flagstaff, Arizona Metropolitan Statistical Area. The population was 134,421 at the 2010 census. The county seat is Flagstaff. It is the second largest county by land area in the 48 contiguous United States, behind San Bernardino County, California, with its 18,661 square miles (48,300 km2) making it larger than each of the nine smallest states.
Coconino County contains Grand Canyon National Park, the Havasupai Nation, and parts of the Navajo Nation, Hualapai Nation, and Hopi Nation. It takes its name from Cosnino, a name applied to the Havasupai.
After the building of the Atlantic & Pacific Railroad in 1883 the region of northern Yavapai County began experiencing rapid growth. The people of the northern reaches had tired of the rigors of travelling all the way to Prescott for county business. They also believed that they were a significant enough entity that they should have their own county jurisdiction. Therefore, they decided in 1887 to petition for secession from Yavapai and the creation of a new Frisco County. They remained part of Yavapai, however, until 1891 when Coconino County was formed and its seat declared to be Flagstaff.
According to the 2000 census, the county has a total area of 18,661.21 square miles (48,332.3 km2), of which 18,617.42 square miles (48,218.9 km2) (or 99.77%) is land and 43.79 square miles (113.4 km2) (or 0.23%) is water. It is the second largest county in the U.S. (excluding boroughs in Alaska) after San Bernardino County in California and is also physically larger than many European nation-states. It has more land area than each of the following U.S. states: Connecticut, Delaware, Hawaii, Maryland, Massachusetts, New Hampshire, New Jersey, Rhode Island, and Vermont. The highest natural point in Arizona, Humphreys Peak at 12,637 feet (3,852 m), is located in Coconino County, as is the Barringer Meteor Crater.
