The Circumferential Highway is the common name for a freeway bypass around the city of Nashua in southern New Hampshire, most of which has not yet been built. The purpose of the highway is to provide easier access to the F.E. Everett Turnpike and U.S. Route 3 in Nashua. Most of the highway is planned to be built in Hudson, with small sections also built through the towns of Litchfield and Merrimack as well as the city of Nashua.

The extant road does not have a state route designation, and is signed as "TO US 3 / Everett Turnpike" in the westbound direction and "TO NH 3A" in the eastbound direction.
