National routes in South Africa are a class of trunk roads and freeways which connect major cities. They form the highest category in the South African route numbering scheme, and are designated with route numbers beginning with "N", from N1 to N18. Most segments of the national route network are officially proclaimed National Roads that are maintained by the South African National Roads Agency (SANRAL), but some segments are maintained by provincial or local road authorities.

Regional routes are the third category of road in the South African route numbering scheme. They are designated with the letter "R" followed by a three-digit number. They serve as feeders connecting smaller towns to the national and provincial routes. Designation as a regional road does not necessarily imply any particular size of road; they range from gravel roads to multi-lane freeways.
