Fairburn is a city in Fulton County, Georgia, United States, with a population of 12,950, according to the 2010 census. Though it has a rich history of its own, the city is now a closely linked suburb of Atlanta, which lies just 17 miles to the north.
Fairburn is located along a railroad line and was the county seat of Campbell County starting in 1871. It was chosen as county seat in a referendum in 1871 that was spurred by the original seat of Campbellton refusing to allow the Atlanta & West Point Railroad line through on account of the anticipated noise in the 1850s. The railroad instead passed through Fairburn. Campbellton then faded away as Fairburn grew. The government of Campbell County went bankrupt in 1931 during the Great Depression and, along with Milton County to the north, was absorbed into Fulton County when 1932 began.
