U.S. Route 3 is a north-south United States highway that runs from its southern terminus in Cambridge, Massachusetts (the official end according to AASHTO is at US 20 across the Charles River in Boston, though current signs indicate a terminus in Cambridge at Route 2A/3) through New Hampshire to its terminus at the Canadian border. In New Hampshire parts of US 3 are known as "Daniel Webster Highway" or "Old Route 3". In some places it is a freeway: in Massachusetts it is a freeway from Burlington, Massachusetts to the New Hampshire border, with the freeway continuing into southern New Hampshire as the Everett Turnpike (US 3 runs along the first 6.7 miles of the Everett Turnpike). In northern New Hampshire US 3 runs along Interstate 93, then the Franconia Notch Parkway, and then another segment of Interstate 93 ending at the border with Canada. While the southern terminus has not changed there have been different northern termini to this route.

Route 3 continues beyond Boston to Cape Cod, but has never been part of US 3.
