McKinney is a city in and the county seat of Collin County, Texas, United States. It is Collin County's third-largest city, after Plano and Frisco. A suburb of the Dallas–Fort Worth metroplex, McKinney is about 32 miles (51 km) north of Dallas.

The Census Bureau ranked McKinney as the nation's fourth fastest-growing large city from 2010 to 2019 and determined the city's 2020 population was 195,308. Based on Census Bureau estimates, as of July 2022 the city's population was 207,507, making it Texas's 15th-most populous city.

On March 24, 1849, William Davis, who owned 3,000 acres (12 km) where McKinney now stands, donated 120 acres (0.49 km) for the townsite. Ten years later, McKinney incorporated, and in 1913, the town adopted the commission form of government.

For its first 125 years, McKinney served as the county's principal commercial center. The county seat provided farmers with flour, corn, cotton mills, cotton gins, a cotton compress, and a cottonseed oil mill, as well as banks, churches, schools, newspapers, and from the 1880s, an opera house. Businesses also came to include a textile mill, an ice company, a large dairy, and a garment-manufacturing company. The population grew from 35 in 1848 to 4,714 in 1912. By 1953, McKinney had a population of more than 10,000 and 355 businesses. The town continued to serve as an agribusiness center for the county until the late 1960s.

By 1970, Plano surpassed McKinney in size. McKinney experienced moderate population growth, from 15,193 in the 1970 census to 21,283 in the 1990 census. By the mid-1980s, the town had become a commuter center for residents who worked in Plano and Dallas. In 1985, it had a population of just over 16,000 and supported 254 businesses. Since then, McKinney's rate of increase has been much more dramatic. In the 2000 census, McKinney had grown to 54,369 with 2,005 businesses and in the 2010 census the population had more than doubled to 131,117 residents. The Census Bureau's July 2015 estimate placed the population of McKinney at 162,898. A later estimate placed the city population as of January 1, 2019 as 187,802.
