Gros Morne National Park is a world heritage site located on the west coast of Newfoundland. At 1,805 km2 (697 sq mi), it is the second largest national park in Atlantic Canada.

The park takes its name from Newfoundland's second-highest mountain peak (at 2,644 ft/806 m) located within the park. Its French meaning is "large mountain standing alone," or more literally "great sombre." Gros Morne is a member of the Long Range Mountains, an outlying range of the Appalachian Mountains, stretching the length of the island's west coast. It is the eroded remnants of a mountain range formed 1.2 billion years ago. "The park provides a rare example of the process of continental drift, where deep ocean crust and the rocks of the earth's mantle lie exposed."

The Gros Morne National Park Reserve was established in 1973. It wasn't until October 1, 2005 that the National Parks Act was applied to the reserve, thereby making it a Canadian National Park.

Gros Morne National Park of Canada was designated a UNESCO World Heritage Site in 1987.

The park is an area of great natural beauty with a rich variety of scenery, widlife, and recreational activities. Visitors can hike through wild, uninhabited mountains and camp by the sea. Boat tours bring visitors under the towering cliffs of a freshwater fjord carved out by glaciers. Waterfalls, marine inlets, sea stacks, sandy beaches, and colourful nearby fishing villages complete the phenomenal natural and cultural surroundings of Gros Morne National Park of Canada.
