Fort McPherson was a U.S. Army military base located in Atlanta, Georgia, bordering the northern edge of the city of East Point, Georgia. It was the headquarters for the U.S. Army Installation Management Command, Southeast Region; the U.S. Army Forces Command; the U.S. Army Reserve Command; the U.S. Army Central.
Named after Major General James Birdseye McPherson, this fort was founded by the U.S. Army in September 1867. During the Reconstruction Era, it was named the "McPherson Barracks", and it served as a post for the Federal troops who were occupying Atlanta. With the end of Reconstruction, the McPherson Barracks was closed and sold off in 1881, though the site continued to be occupied during the summers by U.S. troops stationed in Florida. In 1885, the land was again purchased by the Army at which to station ten army companies.
