Pinal County is in the central part of the U.S. state of Arizona. According to the 2020 U.S. Census, the population of the county was 425,264, making it Arizona's third-most populous county. The county seat is Florence. The county was founded in 1875.
Pinal County contains parts of the Tohono Oʼodham Nation, the Gila River Indian Community and the San Carlos Apache Indian Reservation, as well as all of the Ak-Chin Indian Community.
Pinal County is included in the Phoenix–Mesa–Scottsdale, Arizona Metropolitan Statistical Area. Suburban growth southward from greater Phoenix has begun to spread into the county's northern parts; similarly, growth northward from Tucson is spreading into the county's southern portions. The Pinal County cities of Maricopa and Casa Grande, as well as many unincorporated areas, have shown accelerated growth patterns in recent years; such suburban development is likely to continue for the foreseeable future.
