U.S. Route 5 (US 5) is a part of the United States Numbered Highway System that runs from New Haven, Connecticut, to the Canada–United States border at Derby Line, Vermont. In Vermont, the road runs south–north from the Massachusetts state line near Guilford to the international border. The 192.317 miles (309.504 km) that lie in Vermont are maintained by the Vermont Agency of Transportation (VTrans) and run largely parallel to Interstate 91 (I-91). US 5 also follows the path of the Connecticut River from the Massachusetts border to St. Johnsbury, where the river turns northeast while US 5 continues north. The highway serves the major towns of Brattleboro, Hartford, and St. Johnsbury, along with the city of Newport near the Canadian border.

Before the development of the Numbered Highway System, US 5 was designated Route 2 and was part of the New England road marking system that existed from 1922 to 1927. When the highway system was formed in November 1926, the former Route 2 was commissioned as US 5. At this point, the road was not paved. It was not paved until the state of Vermont started overseeing the maintenance of the highway in 1931. The road was completely paved by 1933.
