A sidewalk, or pavement, footpath, footway, and sometimes platform, is a path along the side of a road. A sidewalk may accommodate moderate changes in grade (height) and is normally separated from the vehicular section by a curb (British English: kerb). There may also be a road verge (a strip of vegetation, grass or bushes or trees or a combination of these) either between sidewalk and the roadway (British English: carriageway) or between the sidewalk and the boundary.

In some places, the same term may also be used for a paved path, trail or footpath that is not next to a road, for example, a path through a park.
