The 14th Arkansas Infantry Regiment or Powers' Arkansas Infantry Regiment (1861–1865) was a Confederate Army infantry regiment during the American Civil War. Two Arkansas units received the designation 14th. The other 14th Arkansas Infantry Regiment was commanded by Colonel James H. McCarver. The unit participated in the Pea Ridge Campaign in Arkansas and then moved east of the Mississippi River, with General Earl Van Dorn's Army of the West. After participating in the Iuka-Corinth Campaign, the unit became part of the garrison of Port Hudson, Louisiana. Following the surrender of Port Hudson, the unit returned to Arkansas and was consolidated with other units that had been released following their capture to form the 1st Arkansas Consolidated Infantry Regiment (Trans-Mississippi).
