The Long Range Mountains are a series of mountains along the west coast of the Canadian island of Newfoundland. They also form the northenmost section of the Appalachian chain on the eastern seaboard of North America. In 2003 it was announced that the International Appalachian Trail would be extended through the Long Range Mountains.
Running along the Gulf of St. Lawrence, the range is comprised of the following sections:
- Anguille Mountains,
- Lewis Hills,
- Tablelands (including some of the oldest exposed rock on the planet)
- main section of the Long Range Mountains (running northeast from the Tablelands through Gros Morne National Park, this is the only part of North America's east coast (south of Labrador) that is indented by fjords)
