The Fourth Corps Area was a Corps area of the United States Army from 20 August 1920 to 7 December 1941. It replaced the Southeastern Department based in Charleston, South Carolina and was originally headquartered there. The headquarters was then transferred to Atlanta, Georgia, and encompassed the states of Alabama (transferred in December 1920), Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina and Tennessee.

Its formations included Third Army (1936–40); IV Corps with 4th Division, 30th Division, and 31st Division; XIV Corps with 81st Division, 82d Division, and 87th Division; Fourth Coast Artillery District; and Fourth Corps Area Service Command.

The Fourth Corps Area Training Center was established in 1921, originally at Camp McClellan, Alabama, to train regular army and organized reserve units, as well as ROTC cadets and CMTC candidates.

With the adoption of the four field army plan on 1 October 1933, the mobile units of the Fourth Corps Area were reassigned to the Third Army or GHQ Reserve, or were demobilized.

The Fourth Corps Area was redesignated as the Fourth Corps Area Service Command (CASC) in May 1941 and redesginated again as Fourth Service Command 22 July 1942.
