NC 104 is a six-mile (10 km) North Carolina State Highway. It connects northwest Surry County with downtown Mt. Airy.

NC 104 ends at the VA-NC border. NC 104 used to continue on as VA 104 but is now Virginia Secondary Route 773.

There is also a historical marker to commemorate the state line.

The road slowly heads south and quickly enters the outskirts of Mt. Airy.

NC 104 is highly unmarked and six miles (10 km) after it begins, NC 104 ends at NC 103 without as much as a guide sign.

It has not been renumbered since.
