The Maryland Scenic Byways system consists of nineteen byways that pass through scenic and historic areas across the U.S. state of Maryland, with four of them designated as National Scenic Byways and two of them designated as All-American Roads. The byways pass through a variety of surroundings, such as the mountains of Western Maryland, the rolling countryside in the northern part of the state, urban sites in the Baltimore and Washington, D.C. areas, small towns and wildlife areas along the Chesapeake Bay, and beaches along the Atlantic Ocean. The byways also serve historical sites ranging from colonial settlement, the War of 1812, and the American Civil War, along with byways that follow the historic routes of the National Road, the Chesapeake and Ohio Canal, and the Underground Railroad.

The Historic National Road Scenic Byway travels from Keysers Ridge to Baltimore along the historic route of the National Road, a road that connected Baltimore to Vandalia, Illinois. The road is designated an All-American Road.
