Pinal County is located in the central part of the U.S. state of Arizona. According to U.S. Census Bureau estimates in 2019, the population of the county was 462,789, making it Arizona's third-most populous county. The county seat is Florence. The county was founded in 1875.
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 northern parts of the county; similarly, growth northward from Tucson is spreading into the southern portions of the county. 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.
Pinal County was carved out of neighboring Maricopa County and Pima County on February 1, 1875, during the Eighth Legislature. In the August 18, 1899, issue of The Arizona Magazine, the name "Pinal" is said to come from the pine-clad Pinal Mountains. Pinal County was the second-fastest-growing county in the U.S. between 2000 and 2010.
In 2010, CNN Money named Pinal County as the second fastest growing county in the USA.

During the 20th century, Pinal was very much a bellwether county in U.S. presidential elections, having supported the winning candidate in every election between Arizona's statehood in 1912 and 2004 except for that of 1968, when Hubert Humphrey won the county by 3.2 percentage points but lost to Richard M. Nixon. As a result of the urban sprawl from Phoenix spreading into the county, a major political reversal has taken place between it and neighboring Maricopa County since the turn of the millennium. Pinal voters now trend more Republican than traditionally conservative Maricopa County, and it has become a safely Republican county. Donald Trump carried the county by the second-largest margin for a Republican since statehood.
Salaries for county elected officials are set by the Arizona Revised Statutes. All county elected officials except the Sheriff (Mark Lamb as of 2017) and the County Attorney make a salary of $63,800, along with county benefits and compulsory participation in the Arizona State Elected Official Retirement Plan.
