CSS Jackson was an ironclad ram built for the Confederate States Navy during the American Civil War. The CSS Jackson was known as Muscogee until she was launched; after that all surviving Confederate records refer to the ship as the "ironclad ram Jackson." She was built in 1862 at Columbus on the banks of the Chattahoochee River, Georgia, and then launched and commissioned in December 1864. The Columbus Naval Iron Works supplied the machinery used aboard the Jackson. The ship faced setbacks that ultimately prevented her from entering service and engaging the Union blockade.
