North Dakota Highway 30 (ND 30) is a state highway in the U.S. state of North Dakota. The highway is currently broken up into three separate segments across the eastern half of North Dakota.

ND 30 begins at ND 13 in Lehr and runs north for 25.4 miles before turning left to remain north at ND 46's western terminus near Streeter. ND 30 remains heading due north until it breaks at I-94 near Medina. The road beyond the interchange leads to a county highway connecting I-94 to Medina.

The longest section of ND 30 starts at US 52 and ND 200 near Sykeston, and runs north for 13 miles until coming to a three way intersection with ND 15. ND 30 turns west for a 4.5 mile long concurrency before turning right to head back north again. For the next 30 miles, ND 30 connects Hamberg and Maddock with ND 19, and continues further north for 17.2 miles, breaking again at US 2 near York. Harlow is another community that ND 30 connects along the way.

ND 30 resumes again, this time at ND 66 near Mylo, and runs north for 13.8 miles before intersecting US 281 and ND 5 in Rolla. North of Rolla, ND 30 ends at the Canadian border with no major intersections between the two, though it comes close to both Turtle Mountain State Forest, and the International Peace Garden, with a paved side road (106th Street NE) providing access.
