Gas prices in North Carolina: Lower Atlantic average and state gas tax

There's no official weekly average just for North Carolina. What there is: the Lower Atlantic regional average, which the state is part of, at $4.16 for regular this week (September 21, 2026). That's −31.5¢ versus the whole country. Taxes are a big part of the story: North Carolina's state gas tax and fees total 41.2¢ per gallon (10th of 51, highest first), and diesel carries 41.2¢. Since January 2015, the gasoline rate has moved +3.5¢.
