New Hampshire Route 11 is a 108.223-mile-long (174.168 km) east–west state highway in New Hampshire, running completely across the central part of the state. Its western terminus is at the Vermont state line in Charlestown, where it continues west as Vermont Route 11. The eastern terminus is at the Maine state line in Rochester, where it crosses the border with U.S. Route 202 and continues as Maine State Route 11.

Its number is derived from its original 1925 designation as New England Interstate Route 11.

The highway follows a generally southwest to northeast alignment from the Vermont state line until reaching Lake Winnipesaukee, then turns southeast for the remainder of its routing to the Maine state line.

There are 3 auxiliary routes, labeled 11A through 11C, all located along the shores of Lake Winnipesaukee, and an additional former auxiliary route, 11D, which is still known by that name.
