New Hampshire Route 16 (NH 16) is a 154.771-mile (249.080 km), north–south state highway in New Hampshire, United States, the main road connecting the Seacoast region to the Lakes Region and the White Mountains. 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 Milton and Chocorua, and between Conway and Glen, it is known as the White Mountain Highway. It is known as Chocorua Mountain Highway between Chocorua and Conway and various other local names before crossing into Maine about 20 miles (32 km) south of the Canadian border. Portions of NH 16 run concurrent with U.S. Route 4 (US 4), US 202, NH 25, and US 302, and US 2.

The 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 Location, where it continues as Maine State Route 16.

There are three auxiliary routes of NH 16, two loops labeled 16A and one labeled 16B.
