The following is a list of United States numbered highways. It includes U.S. Numbered Highways both past and present, with the former shaded in gray. Three-digit subsidiaries are grouped with their one- or two-digit parent.

The list is based on American Association of State Highway and Transportation Officials (AASHTO) definitions, with up-to-date details on extensions and truncations, though distances are as of 1989. Discrepancies with state specifications are noted.

A list of bannered U.S. Routes is also available.

New York signs the west end of the east segment at US 11 south of the border crossing; Maine signs the east end at I-95 west of the border crossing
