From the article Nordic countries:

The Nordic countries make up a region in Northern Europe and the North Atlantic which consists of Denmark, Finland, Iceland, Norway and Sweden and their associated territories which include the Faroe Islands, Greenland and Åland. Scandinavia is sometimes used as a synonym for the Nordic countries, although within the Nordic countries the terms are considered distinct.

And from Scandinavia:

Scandinavia is a historical and geographical region in northern Europe that includes, and is named after, the Scanian Province. It consists of the kingdoms of Norway, Sweden, and Denmark. While some authorities argue for the inclusion of Finland and Iceland, in Scandinavia the term is used unambiguously to refer only to Denmark, Norway and Sweden, which share a mutually intelligible language (a dialect continuum), ethnic composition and have close cultural and historic bonds, to a degree that Scandinavians may be considered one people (see scandinavism).
