The Army of West Virginia served in the Union Army during the American Civil War and was the primary field army of the Department of West Virginia. It campaigned primarily in West Virginia, Southwest Virginia and in the Shenandoah Valley. It is noted for having two future U.S. presidents serve in its ranks: Rutherford B. Hayes and William McKinley, both from the 23rd Ohio Infantry. With fighting in the Valley ended, the Army of West Virginia's designation was discontinued.
