Skræling is the name the Norse Greenlanders used for the peoples they encountered in North America. In surviving sources, it is first applied to the Thule people, the proto-Inuit group with whom the Norse coexisted in Greenland after about the 13th century. In the sagas, it is also used for the peoples of the region known as Vinland whom the Norse encountered and fought during their expeditions there in the early 11th century.

The Norse exploration of North America began in the late 10th century, when Norsemen explored areas of the North Atlantic colonizing Greenland and creating a short term settlement near the northern tip of Newfoundland. This is known now as L'Anse aux Meadows where the remains of buildings were found in 1960 dating to approximately 1,000 years ago. This discovery helped reignite archaeological exploration for the Norse in the North Atlantic. This single settlement, located on the island of Newfoundland and not on the North American mainland, was abruptly abandoned.
