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 the Mississippi, which was then re-organized as the Army of Tennessee on November 20, 1862.
