List of road routes in the Northern Territory

Road routes in the Northern Territory assist drivers navigating roads throughout the territory, by identifying important through-routes. The Northern Territory's National Highways are the main routes connecting Darwin to the adjacent states of Queensland, South Australia, and Western Australia. National Routes spur off the National Highways, and are other routes of national importance, while the remaining significant routes are designated as State Routes.

According to the New South Wales Roads and Maritime Services, the Northern Territory has begun converting their numbered routes to alphanumeric routes, with a "progressive replacement" scheme that sees alphanumeric route markers introduced only when signs are replaced.

There are three national highways and three national routes in the Northern Territory.

State routes are numbered based on their position in the territory, generally increasing in number from south to north.
