The 154th Infantry Regiment ("Third Arkansas") was a United States infantry regiment, which was created from the 1st and 2nd Battalions of the 3rd Arkansas Infantry Regiment, Arkansas National Guard, in 1917. The Regiment was activated as for World War I, re-designated as the 154th Infantry and shipped to France as a part of the 39th Infantry Division (United States), but became a replacement regiment and its personnel were reassigned to other AEF units. The 154th Infantry Regiment was never reactivated in the Arkansas National Guard following World War I.
