The Army of Central Kentucky was a military organization within Department No. 2 (the Western Department of the Confederate States of America). Originally called the Army Corps of Central Kentucky, it was created in the fall of 1861 as a subsection of Department No. 2, and continued in existence until the end of March 1862 when it was absorbed and merged into the Army of Mississippi, which was then re-organized as the Army of Tennessee on November 20, 1862.
