The Hampton Roads Beltway is a loop of Interstate 64 and Interstate 664, which links the communities of the Virginia Peninsula and South Hampton Roads which surround the body of water known as Hampton Roads and comprise much of the region of the same name in the southeastern portion of Virginia in the United States. It crosses the harbor of Hampton Roads at two locations on large four-laned bridge-tunnel facilities: the eastern half carries Interstate 64 and uses the Hampton Roads Bridge-Tunnel and the western half carries Interstate 664 and uses the Monitor-Merrimac Memorial Bridge-Tunnel. The beltway has the clockwise direction signed as the Inner Loop, and the counter-clockwise direction signed as the Outer Loop. The entire beltway, including the bridge-tunnels, is owned and operated by the Virginia Department of Transportation.

Interstate 64 (I-64) in the US state of Virginia runs east–west through the middle of the state from West Virginia to the Hampton Roads region, for a total of 299 miles (481 km). From the West Virginia state line to Chesapeake, it passes through the major cities of Lexington, Staunton, Charlottesville, the state capital of Richmond, Newport News, Hampton, and Norfolk. It is notable for crossing the mouth of the harbor of Hampton Roads on the Hampton Roads Bridge–Tunnel (HRBT), the first bridge–tunnel to incorporate artificial islands, concurrent with U.S. Route 60 (US 60). Also noteworthy is a section through Rockfish Gap, a wind gap in the Blue Ridge Mountains, which was equipped with an innovative system of airport-style runway lighting embedded into the pavement to aid motorists during periods of poor visibility due to fog or other conditions.
