The Appalachian Uplands is one of the seven physiographic regions in Canada,^[1] distinguished by its topography and geology. The region includes southern Quebec, Gaspésie, New Brunswick, Nova Scotia, Prince Edward Island and the island of Newfoundland.^[1] This is the Canadian portion of the Appalachian Mountains. The United States equivalent portion is called the Appalachian Highlands.

The Geologic Survey of Canada uses three levels of physiographic classification. The "region" is the highest level, which is equivalent to the "division" level in the United States. In the Appalachian Uplands, there is no second-level, which in Canada is the "subregion." There are 13 tertiary level areas (called divisions in Canada) in the Appalachian Uplands region. ^[1]
