Pima County is a county in the south central region of the U.S. state of Arizona. As of the 2020 census, the population was 1,043,433,[1] making it Arizona's second-most populous county. The county seat is Tucson,[2] where most of the population is centered. The county is named after the Pima Native Americans, also known as Tohono O'odham, who are indigenous to this area.
Pima County includes the entirety of the Tucson Metropolitan Statistical Area, and it is the third largest metropolitan area in the Southwestern United States.
Pima County contains parts of the Tohono O'odham Nation, as well as all of the San Xavier Indian Reservation, the Pascua Yaqui Indian Reservation, Organ Pipe Cactus National Monument, Ironwood Forest National Monument and Saguaro National Park.
The vast majority of the county population lies in and around the city of Tucson, filling much of the eastern part of the county with urban development. As Arizona's second-largest city, Tucson is a major commercial and academic center. Other urban areas include the Tucson suburbs of Marana, Oro Valley, Sahuarita, South Tucson, and Green Valley. The rest of the county is sparsely populated; the largest towns are Sells, the capital of the Tohono O'odham Nation, and Ajo in the county's far western region.
Pima County, one of the four original counties in Arizona, was created by the 1st Arizona Territorial Legislature with land acquired through the Gadsden Purchase from Mexico in 1853. The original county consisted of all of Arizona Territory east of longitude 113° 20' and south of the Gila River.[3] Soon thereafter, the counties of Cochise, Graham and Santa Cruz were carved from the original Pima County.[4]

Pima County is governed by a five-member Board of Supervisors who set ordinances and run services for the areas that do not fall within any city or town's jurisdiction.
In Arizona, counties are creatures of the state, and do not have charters of their own. The county Board of Supervisors acts under powers delegated by state law, mainly related to minor ordinances and revenue collection. With few exceptions, these powers are narrowly construed. The state legislature devotes considerable time to local matters, with legislative approval required for many of the most basic local issues.
The Pima County Board of Supervisors is responsible for steering public policy in the region. The five-member board provides direction to the County Administrator, Jan Lesher,[15] and the county's various departments as they work to ensure safe communities, nurture economic development, sustainably manage natural resources and protect public health. In addition to overseeing the delivery of a host of municipal services, from roads to parks and libraries and law enforcement, board members also are responsible for approving the county budget. Elected to four-year terms, board members also set the amount of taxes to be levied.

Being home to a major population center and a major research university, Pima County is one of the most reliably Democratic counties in Arizona. After voting Democratic through 1930s and 1940s, it swung Republican following major population increase after World War II, becoming a Republican-leaning county. However, in 1964, it rejected Arizona's native son Barry Goldwater by seven points, who won statewide by one point. However, despite the county's Republican lean, Democrats would not win 40% of the vote only twice - in 1972, when George McGovern lost in a 49-state landslide and due to a balloting error in the county, the Socialist Workers Party came a distant third with 18% of the vote;[25] and in 1980, when Jimmy Carter, being largely insensitive to Western states' issues, also lost many votes to independent John B. Anderson. Following Bill Clinton's plurality victory by 12 points in 1992, all Democrats since 1996 have won the county by a majority and no Republican has come closer than six points in recapturing the county. In both 2016 and 2020, Donald Trump became the first Republican since Bob Dole in 1996 to fail to win 40% of the county's vote.
