The 1st Louisiana Field Battery was an artillery unit recruited from volunteers in Louisiana that fought in the Confederate States Army during the American Civil War. The battery mustered into Confederate service in October 1861. The unit traveled to Fort Jackson in early 1862 and took part in the defense of Forts Jackson and St. Philip. The soldiers became prisoners when the forts surrendered and the battery reformed at Franklin after their prisoner exchange. The battery fought at Fort Bisland and Irish Bend in 1863. Later in the year the battery engaged Union shipping on the rivers in several actions. In 1864 the battery briefly fought at Mansfield before its commander was killed while engaging Union gunboats in late April. The unit also fought at Mansura and Yellow Bayou. The battery was in Texas when the Trans-Mississippi Department surrendered in May 1865.
