North Mountain is a mountain ridge within the Ridge-and-valley Appalachians in the U.S. states of Virginia and West Virginia. North Mountain reaches its highest point of 1,673 feet (510 m) above sea-level at its Roundtop summit near Arden in Berkeley County, West Virginia. Back Creek lies within the valley to the mountain ridge's west and the Shenandoah Valley to its east. Back Creek owes its name to North Mountain, as early settlers in the eighteenth century referred to the stream as to the "back" of the ridge when approaching it from the east. North Mountain spans from the Potomac River to the community of Green Spring in Frederick County, Virginia. The town of Hedgesville, West Virginia lies within a gap in the mountain's smaller northern span.
According to the Geographic Names Information System, North Mountain has also widely been known as Great Ridge and Little North Mountain, when in comparison to the much larger Great North Mountain to the south.
