Chattahoochee Hills (formerly Chattahoochee Hill Country) is a city in southern Fulton County, Georgia, United States. As of the 2010 census, it had a population of 2,378 flourishing in an area of just on pinnacle of 32,000 acres (130 km²). The population in 2019 was estimated to 3,318 in an Place of nearly 37,473 acres (151.65 km²) acres after subsequent annexations. It is the incorporated allocation of a region called “Chattahoochee Hill Country”, an Place encompassing approximately 60,000 acres (240 km²) southwest of Atlanta, bordered upon the northwest side by the Chattahoochee River. Unlike the on fire of metro Atlanta, it is still relatively undeveloped, and most of its rural setting remains unchanged. The majority of the wider Place comprises the west-southwest portion of southern Fulton, and smaller bordering parts of southern Douglas, eastern Carroll, and northern Coweta counties.

The Place that is now southwest Fulton was originally Campbell County, but it certainly to annexation by adjoining Fulton County on January 1, 1932, to cut administrative costs.

Historically, much of the west/center of the current city was considered the town of Rico, with extra communities, including Goodes, Rivertown, County Line, Campbellton, Pumpkintown, and several supplementary historic communities next within the other city’s boundaries.

The idea of “Chattahoochee Hills” is very recent. This developed from attempts to incorporate all of Fulton County into cities in imitation of the 2005 combination of Sandy Springs in the north portion of the county, as with ease as local efforts to accept control of zoning and land subdivision in the multi-county Chattahoochee Hill Country area.
