A parkway is a general designation of a type of limited-access highway in some parts of the US and Canada. (In other parts of the US, the term parkway may merely be another title for a normal surface street) Like all limited-access highways, parkways are designed particularly for through traffic, and many can be classified generally as freeways or toll highways. Many parkways are restricted to non-commercial traffic and cars; trucks, buses, and the like are banned.

Historically, the term "parkway" has often implied that the road was designed specifically with a naturalistic or manicured landscaping of the median and adjacent land areas meant to suggest a pastoral driving experience, isolated from the manifestations of commerce and advertising, even when the road passes through populated areas; for this reason commercial traffic is excluded. Many parkways have signature road signs with special emblems that suggest a thematic driving experience and increase the sense of isolation from civilization in the vicinity of the road.
