The 4th Missouri Infantry Regiment was formed on April 28, 1862, and served in the Confederate States Army during the American Civil War. The infantry regiment did not see action at the Battle of Farmington on May 9, and the Battle of Iuka on September 19 despite being part of the Confederate force present at those battles. As part of Brigadier General Martin E. Green's brigade, the regiment participated in three charges against Union lines on October 3, 1862, during the Second Battle of Corinth. The following day, the regiment, along with the rest of Green's brigade, attacked the new Union lines. Despite initial success, the attack was repulsed by a Union counterattack. The regiment ceased to exist as a separate unit when it was combined with the 1st Missouri Infantry Regiment on November 7, 1862, to form the 1st and 4th Missouri Infantry Regiment (Consolidated).

The combined unit served in the Vicksburg campaign in 1863, before surrendering at the end of the siege of Vicksburg. After undergoing a prisoner exchange, the men rejoined the Confederate Army and served in the Atlanta Campaign and the Battle of Franklin in 1864, still as part of the 1st and 4th Missouri Infantry Regiment (Consolidated). On May 9, 1865, near the end of the war, the consolidated regiment surrendered during the Battle of Fort Blakely, ending the unit's existence. The 4th Missouri Infantry's battle flag is displayed at the American Civil War Museum.
