The 326th Infantry Regiment was an infantry regiment of the United States Army that saw active service during World War I, as part of the 82nd Division and fought in the Meuse-Argonne Offensive and was inactivated in 1919. The regiment was reactivated during World War II, again as part of the 82nd Infantry Division, and was converted into a glider infantry formation, becoming the 326th Glider Infantry Regiment. Originally part of the 82nd Airborne Division, the regiment transferred to the 13th Airborne Division. However, despite training for almost three years, the 326th was never involved in any combat.
