Fort Knox is a United States Army post in Kentucky south of Louisville and north of Elizabethtown. The 109,054-acre (44,133 ha) base covers parts of Bullitt, Hardin, and Meade counties. It currently holds the Army Human Resources Center of Excellence to include the Army Human Resources Command, United States Army Cadet Command and the United States Army Accessions Command. It was the home, for nearly seventy years (1940-2010), of the U.S. Army Armor Center, the U.S. Army Armor School (now at Fort Benning), and was used by both the Army and the Marine Corps to train crews on the M1 Abrams main battle tank. The history of the US Army's Cavalry and Armored forces, and of General George S. Patton's career, can be found at the General George Patton Museum on the grounds of Fort Knox. Parts of the base in Hardin and Meade Counties form a census-designated place (CDP), which had a population of 12,377 at the 2000 census.

The United States Department of the Treasury has maintained the Bullion Depository on the post since 1937.
