Fort Gillem was a United States Army Post located in Forest Park, Georgia, on the southeast edge of Atlanta in Clayton County. Founded in 1941, it was a satellite installation of nearby Fort McPherson. The base housed different supply and support units, including the U.S. Army Criminal Investigation Laboratory and the 3rd MP Group (CID), both units of the United States Army Criminal Investigation Command. It employed 456 active duty personnel, 1,663 Army reservist, and 1,667 civilians. In 1973, its 1,465 acres (5.93 km2) were annexed by Forest Park. The fort was named in the memory of Lieutenant General Alvan Cullom Gillem, Jr.
