The 18th Arkansas Infantry Regiment, also known as "Carroll's regiment," was an infantry formation of the Confederate States Army during the American Civil War. The regiment was raised in 1862 under the command of Colonel D. W. Carroll.

The regiment served east of the Mississippi in several actions before being surrendered at Port Hudson in July 1863. Reorganized, the regiment was finally merged with several other Arkansas units to form the 2d Consolidated Arkansas Infantry.

There was another regiment designated as the 18th Arkansas. When Lieutenant-Colonel J. S. Marmaduke's 1st Arkansas Infantry Battalion was increased to a regiment, it was briefly designated as the 18th Arkansas Infantry. Marmaduke's regiment was subsequently redesignated as the 3d Confederate Infantry.Howerton, Bryan R.
