Virginia State Route 7 (VA 7) is a major primary state highway and busy commuter route in Northern Virginia, United States. It travels southeast from Downtown Winchester to Washington Street (SR 400) in Downtown Alexandria. Its route largely parallels those of the Washington & Old Dominion Trail and the Potomac River. Between its western terminus and I-395, SR 7 is part of the National Highway System. In 1968, the Virginia State Highway Commission designated the road as the "Harry Flood Byrd Highway" between Alexandria and Winchester to commemorate Harry F. Byrd Sr. (1887–1966).
