The city of Gainesville is the county seat of Hall County, Georgia, United States. As of the 2020 census, the city had a population of 42,296. Because of its large number of poultry processing plants, it is often called the "Poultry Capital of the World." Gainesville is the principal city of the Gainesville, Georgia Metropolitan Statistical Area, which is included in the Atlanta–Sandy Springs–Gainesville, Georgia Combined Statistical Area. History Gainesville was established as "Mule Camp Springs" by European-American settlers in the early 1800s. Less than three years after the organization of Hall County on December 15, 1818, Mule Camp Springs was renamed "Gainesville" on April 21, 1821. It was named in honor of General Edmund P.
