New Hampshire Route 16 is a 149.75-mile (241.00 km) long north–south highway in New Hampshire. Much of its length is close to the border with Maine. The section from Portsmouth to Milton is a controlled-access toll highway known as the Spaulding Turnpike. Between the Portsmouth Circle and Dover Point, US 4 is also routed along the Turnpike. Its southern terminus of NH 16 is at the Portsmouth Traffic Circle, intersecting with Interstate 95 and the US 1 Bypass. The northern terminus is at the Maine state line near Wentworth's Location, where it continues as Maine State Route 16.

NH 16 is the main road connecting the Seacoast region to the Lakes Region and the White Mountains. The section north of the Spaulding Turnpike is called the White Mountain Highway.

For the section of NH 16 between Portsmouth and Milton, see the Spaulding Turnpike article.
