Yavapai County is near the center of the U.S. state of Arizona. As of the 2020 census, its population was 236,209, making it the fourth-most populous county in Arizona. The county seat is Prescott.
Yavapai County was one of the four original Arizona counties created by the 1st Arizona Territorial Legislature. The county territory was defined as being east of longitude 113° 20' and north of the Gila River. Soon thereafter, the counties of Apache, Coconino, Maricopa, and Navajo were carved from the original Yavapai County. Yavapai County's present boundaries were established in 1891.
The county is named after the Yavapai people, who were the principal inhabitants at the time the United States annexed the area.
County level law enforcement services have been provided by Yavapai County Sheriff's Office since 1864.
According to the U.S. Census Bureau, the county has a total area of 8,128 square miles (21,050 km2), of which 8,123 square miles (21,040 km2) is land and 4.4 square miles (11 km2) (0.05%) is water. It has about 93% of the area of the U.S. state of New Jersey. It is larger than three U.S. states (Rhode Island, Delaware and Connecticut) and the District of Columbia combined.
The county's topography makes a dramatic transition from the lower Sonoran Desert to the south to the heights of the Coconino Plateau to the north, and the Mogollon Rim to the east. The highest point above sea level (MSL) in Yavapai County is Mount Union at an elevation of 7,979 ft (2,432 m) and the lowest is Agua Fria River drainage, now under Lake Pleasant.

Fourteen of these are integral parts of National Forests listed above, whereas five are managed by the Bureau of Land Management. Some of these extend into neighboring counties (as indicated below):
There are numerous flora and fauna species within Yavapai County. For example, a number of plants within the genus Ephedra and Coreopsis are found in the county. Yavapai County is also the location of several groves of the near-threatened California Fan Palm, Washingtonia filifera.
Approximately 10 miles (16 km) northwest of the town of Bagdad lies the Upper Burro Creek Wilderness Area, a 27,440-acre (11,105 ha) protected area home to at least 150 species of birds and featuring one of the Arizona desert's few undammed perennial streams.
