The 20th Louisiana Infantry Regiment was a unit of volunteers recruited in Louisiana that fought in the Confederate States Army during the American Civil War. The unit began its existence as the 6th Louisiana Battalion in September 1861. The battalion was augmented to regimental strength in January 1862 at New Orleans and served during the war in the Western Theater of the American Civil War. The regiment fought at Shiloh, Farmington, and Perryville in 1862. After being reduced in numbers, the regiment was consolidated with the 13th Louisiana Infantry Regiment and served at Stones River, Jackson, Chickamauga, and Missionary Ridge in 1863. The 13th-20th Consolidated Louisiana fought at Resaca, New Hope Church, Ezra Church, and Nashville in 1864. The consolidation with the 13th Louisiana was discontinued in February 1865 and the regiment was re-consolidated with other units. It fought its final battle at Spanish Fort one month before surrendering in May 1865.
