Daniel Harrison House, also known as Fort Harrison, is a historic home located near Dayton, Rockingham County, Virginia. It was built in 1748, and is a two-story, three bay limestone dwelling with a brick extension added in the early 1800s. It has a steep gable roof and wide chimney caps. It was originally surrounded by a palisade and stories of an underground passage to the nearby spring. During the French and Indian War, the legislature of Virginia designed the house "Fort Harrison." The house is one of the oldest in the Shenandoah Valley, and is closely associated with the early history of Rockingham County.
