Fair Oaks is an unincorporated community and census-designated place (CDP) in Cobb County, Georgia, United States. The population was 9,028 at the 2020 census.
Fair Oaks lies just outside the city limits of Smyrna and Marietta, and the area uses "Smyrna" or "Marietta" for its mailing addresses. Except for actual residents of Fair Oaks, very few locals even know it exists as a separately-counted area. The name is also rarely used by local businesses, even in the immediate area.
The area was named for its many mature native oak trees. This, however, is threatened by nearby Dobbins Air Reserve Base and new Federal Aviation Administration regulations regarding flight paths for takeoff and landing. In 2005, the lower house of the Georgia General Assembly passed a resolution in support of the community, which was built in the early 20th century, well before the military base.https://web.archive.org/web/20051102015930/http://www.legis.state.ga.us/legis/2005_06/fulltext/hr908.htm
