A National Parkway is a designation for a protected area in the United States. The designation is given to a scenic roadway and a protected corridor of surrounding parkland. National Parkways often connect cultural or historic sites. The U.S. National Park Service manages the parkways.

The first parkways in the United States were developed in the late 19th century by landscape architects Frederick Law Olmsted and Beatrix Farrand as roads segregated for pedestrians, bicyclists, equestrians, and horse carriages, such as the Eastern Parkway and Ocean Parkway in Brooklyn, New York. The terminology "parkway" to define this type of road was coined by Calvert Vaux and Olmsted in their proposal to link city and suburban parks with "pleasure roads." Newer roads such as the Bidwell and Lincoln Parkways in Buffalo, New York, were designed for automobiles and are broad and divided by large landscaped central medians. Parkways can be the approach to large urban parks, such as the Mystic Valley Parkway to Boston Common in Boston. Some separated express lanes from local lanes, though this was not always the case.

During the early 20th century, the meaning of the word was expanded to include controlled-access highways designed for recreational driving of automobiles with landscaping. These parkways originally provided scenic routes without at-grade intersections, very slow vehicles, or pedestrian traffic. Their success led to more development however, expanding a city's boundaries, eventually limiting their recreational driving use. The Arroyo Seco Parkway between Downtown Los Angeles and Pasadena, California, is an example of lost pastoral aesthetics. It and others have become major commuting routes, while retaining the name parkway.
