George William Fairfax (January 2, 1724 – April 3, 1787) was a planter in colonial Virginia who represented then-vast Frederick County and later Fairfax County in the House of Burgesses before the American Revolutionary War, by which time he had returned to England (where he was a Loyalist). A mentor and good friend of George Washington, Fairfax made opportunities for the younger Washington through his powerful British family, and Washington assisted him afterward by arranging for the sale of his Virginia property after he returned to Britain.
