North Dakota Highway 21 is an east-west highway in North Dakota. It runs from North Dakota Highway 6 about 5 miles (8.0 km) north of Breien to U.S. Route 85 about 5 miles (8.0 km) ENE of Amidon. The highway is known for the large number of abandonments located along it.
The current ND-24 segment between ND-6 and the current ND-24/ND-1806 junction was originally part of ND-21. This segment was renumbered between 1950 and 1963.
