Scandinavia is a region in Northern Europe, with strong historical, cultural, and linguistic ties. The term Scandinavia in local usage covers the three kingdoms of Denmark, Norway, and Sweden. The majority national languages of these three, belong to the Scandinavian dialect continuum, and are mutually intelligible North Germanic languages. In English usage, Scandinavia also sometimes refers to the Scandinavian Peninsula, or to the broader region including Finland and Iceland, which is always known locally as the Nordic countries.

While part of the Nordic countries, the remote Norwegian islands of Svalbard and Jan Mayen are not in Scandinavia, nor is Greenland, a constituent country within the Kingdom of Denmark. The Faroe Islands are sometimes included.

The name Scandinavia originally referred to the former Danish, now Swedish, region of Scania. Scandinavia and Scandinavian entered usage in the late 18th century, being introduced by the early linguistic and cultural Scandinavist movement. The majority of the population of Scandinavia are descended from several North Germanic tribes who originally inhabited the southern part of Scandinavia and spoke a Germanic language that evolved into Old Norse. Icelanders and the Faroese are to a significant extent descended from the Norse and are therefore often seen as Scandinavian.
