Landis's Missouri Battery, also known as Landis's Company, Missouri Light Artillery, was an artillery battery that served in the Confederate States Army during the early stages of the American Civil War. The battery was formed when Captain John C. Landis recruited men from the Missouri State Guard in late 1861 and early 1862. The battery fielded two 12-pounder Napoleon field guns and two 24-pounder howitzers for much of its existence, and had a highest reported numerical strength of 62 men. After initially serving in the Trans-Mississippi Theater, where it may have fought in the Battle of Pea Ridge, the unit was transferred east of the Mississippi River. The battery saw limited action in 1862 at the Battle of Iuka and at the Second Battle of Corinth.
