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, especially since Scandinavia is by definition made up of the countries Denmark, Norway and Sweden.

The region's five sovereign states and three autonomous regions share much common history as well as common traits in their respective societies, such as political systems and the Nordic model.

Politically, Nordic countries do not form a separate entity, but they co-operate in the Nordic Council. Linguistically, the area is heterogeneous, with three unrelated language groups, the North Germanic branch of Indo-European languages and the Finnic and Sami branches of Uralic languages as well as the Eskimo–Aleut language Greenlandic spoken in Greenland.

The Nordic countries have a combined population of approximately 27 million spread over a land area of 3.5 million km² (Greenland accounts for 60% of the total area).
