The 33rd Alabama Infantry Regiment was an infantry unit from Alabama that served in the Confederate States Army during the U.S. Civil War. Recruited from the southeastern counties of Butler, Dale, Coffee, Covington, Russell and Montgomery, it saw extensive service with the Confederate Army of Tennessee before being nearly annihilated at the Battle of Franklin in 1864. Survivors from the regiment would continue to serve until the final capitulation of General Joseph Johnston in North Carolina in 1865.
