White's Fort was an 18th-century residence and fortification located near the present-day unincorporated community of Hayfield, Frederick County in the U.S. state of Virginia. Alternatively known as the White Hall, the first structure contributing to White's Fort was built between 1732 and 1735 by Dr. Robert White (1688-1752), a Scottish American physician, military officer, pioneer, and planter. White's Fort was later utilized as a fortification by White's son Major Robert White for the protection of European American settlers in the vicinity of Great North Mountain during the French and Indian War. The farm was also the birthplace of Alexander White (1738-1804), an inaugural member of the United States House of Representatives.
