Jackson County is a county located in the U.S. state of Florida, on its northwestern border with Alabama. As of the 2020 census, the population was 47,319. Its county seat is Marianna. Jackson County was created by the Florida Territorial Council in 1822 out of Escambia County, at the same time that Duval County was organized from land of St. Johns County, making them the third and fourth counties in the Territory. The county was named for Andrew Jackson, a General of the War of 1812, who had served as Florida's first military governor for six months in 1821. Jackson County originally extended from the Choctawhatchee River on the west to the Suwannee River on the east. By 1840 the county had been reduced close to its present boundaries through the creation of new counties from its original territory, following an increase of population in these areas. Minor adjustments to the county boundaries continued through most of the 19th century, however.
