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.

Greenlandic Norse is an extinct North Germanic language that was spoken in the Norse settlements of Greenland until their demise in the late 15th century. The language is primarily attested by runic inscriptions found in Greenland. The limited inscriptional evidence shows some innovations, including the use of initial t for þ, but also the conservation of certain features that changed in other Norse languages. Some runic features are regarded as characteristically Greenlandic, and when they are sporadically found outside of Greenland, they may suggest travelling Greenlanders.
