List of subranges of the Appalachian Mountains

No clear distinction exists as to what units qualify as directly related subranges of the Appalachians until the level of mountain.

[6] This list is more comprehensive to account for that variation and includes the parent range of each subrange noted.

Due to the lack of solid distinctions in the requirements of an area to be a range, this list includes most physiographic divisions, many larger ridges, plateaus, mountain complexes, most stratigraphic ridges, certain lowlands and uplands, local highlands, and certain other types of geographic and geological features.

Conversely, the government of Quebec considers the Notre Dame and Mégantic Mountains to be a physiographic region and does not recognize the Appalachian Uplands.

This list primarily uses the Canadian Geological Survey's dictations on physiographic regions, divisions, sections, and subsections.
