Interstate 93 (abbreviated I-93) is an interstate highway in the New England section of the United States. Its southern terminus is in Canton, Massachusetts, in the Boston metropolitan area, at Interstate 95 (map); its northern terminus is near St. Johnsbury, Vermont, at Interstate 91.

For most of its length, Interstate 93 indirectly parallels U.S. Route 3. Particularly in New Hampshire, the two highways have several interchanges with each other, as well as a concurrency through Franconia Notch State Park.
