Pima County is a local government established in 1864 as one of Arizona's four original counties. It covers approximately 9,200 square miles in southern Arizona, serving a population of over one million residents across more than 50 departments. The county seat is Tucson, Arizona's second-largest city and former territorial capital. The Tohono O'odham Nation, home to one of the largest Native American reservations in the United States, also lies within county boundaries.
The county delivers a wide range of public services, spanning public safety, health, parks, libraries, and infrastructure. Its parks and trails system includes dozens of sites ranging from lower desert mountain parks to Mount Lemmon's forests at 9,000 feet elevation. The Loop, a 55-mile multi-use path system, connects communities across the region. The county has also purchased thousands of acres to protect landscapes and historic sites. Major institutions and attractions within the county include Saguaro National Park, the Arizona-Sonora Desert Museum, the Pima Air and Space Museum, and the Kino Sports Complex.
Pima County employs thousands of people across classified and unclassified positions in more than 50 departments. Roles span public administration, land conservation, natural resource management, parks and recreation, infrastructure, public health, and cultural site management. The county offers a comprehensive benefits package that includes healthcare, retirement plans, and paid time off. With the county's population projected to reach 1.4 million by 2041, the organisation continues to grow its workforce to meet expanding service demands.
