New Hampshire Route 101 (NH 101) is a state-maintained highway in southern New Hampshire extending from Keene to Hampton Beach. It is the major east–west highway in the southern portion of the state. Most of its eastern portion is a major freeway linking the greater Manchester area to the Seacoast Region. At 95.189 miles (153.192 km) in length, NH 101 nearly spans the entire width of southern New Hampshire.

The western terminus of NH 101 is in Keene at the junction of NH 9, NH 10, and NH 12. The eastern terminus is in Hampton Beach at the junction with Ocean Boulevard (NH 1A).

Between Exeter and Hampton, NH 101 is known as the Exeter–Hampton Expressway.

There are two current and three former auxiliary routes for NH 101. The current routes are NH 101A, which connects Milford and Nashua, and NH 101E, which parallels the main route in Hampton.
