The Maryland Scenic Byways system consists of nineteen byways that pass through scenic and historic areas across the U.S. state of Maryland. 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 and the Chesapeake and Ohio Canal.

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.

The byway enters Maryland in Garrett County along US 40, following that route to Keysers Ridge. Here, the National Road follows US 40 Alternate, heading through the Savage River State Forest and reaching Grantsville, where the Casselman Bridge is located. The road passes through Frostburg, where the Western Maryland Scenic Railroad is located, and La Vale, where the La Vale Tollgate House is located. The byway comes to Cumberland, which has many historic transportation sites. From Cumberland, the Historic National Road Scenic Byway follows Henderson Avenue and Baltimore Street to I-68, continuing east on I-68 before splitting onto MD 144 and passing through Rocky Gap State Park and Green Ridge State Forest. At this point, the byway follows US 40 Scenic and crosses Sideling Hill. The byway follows MD 144 again and continues to Hancock, where the byway has access to the Chesapeake and Ohio Canal and the Western Maryland Rail Trail.
