Norwegians (Norwegian: Nordmenn ) are an ethnic group and nation native to Norway, where they form the vast majority of the country's population. They share a common culture, history, folklore, and speak the Norwegian language. Norwegians are primarily descended from the Norse of the Early Middle Ages who formed a unified Kingdom of Norway under King Harald Fairhair (the first of the Fairhair dynasty) in the 9th century, therefore making the Norwegian monarchy one of the oldest ones in Europe (having continuously existed for over 1,000 years to date).

During the Viking Age, Norwegians and other Norse peoples conquered, settled and ruled parts of the British Isles, Normandy in northern France, Estonia, the Faroe Islands, Iceland, and Greenland. In addition, they also briefly settled in North America on the territory of present-day Canada, establishing a temporary colony at L'Anse aux Meadows in Newfoundland (or Vinland in Old Norse according to the Norse sagas) in the process. Norwegians are closely related to other descendant peoples of the Norsemen such as Danes, Swedes, Icelanders, and the Faroe Islanders as well as other ethnic groups such as the Scots whose nation they significantly settled and left a lasting impact in, particularly the Northern Isles (that is Orkney and Shetland). Being a Germanic people, Norwegians are also related to the English people, Germans, or Dutch people. The Norwegian art, music, and literature also made significant contributions in the history of mankind.

In the past, Norwegian Vikings had also left a significant impact on Ireland and the Irish people as well as on the Isle of Man and the Manx people respectively. Furthermore, the lasting and notable historical, cultural, social, and genetic legacy that the Norwegian Vikings and settlers had brought about and left in the Gaelic-speaking islands of the British archipelago was further highlighted by the regional hegemony of the Norse–Gaels in the region for several centuries between the Early to High Middle Ages, with the latter founding powerful local kingdoms (i.e. the Kingdom of the Isles, Kingdom of Dublin, and the Lordship of Galloway).

The Norwegian language, with its two official standard forms, more specifically Bokmål and Nynorsk (as well as two unofficial ones, namely Riksmål and Høgnorsk), is part of the larger Scandinavian dialect continuum of generally mutually intelligible languages in Scandinavia. Norwegian people and their descendants are found in migrant communities worldwide, notably in the United States, Canada, Australia, New Zealand, South Africa and the United Kingdom. To date, there are more Norwegians by descent in the United States alone (and in North America in general with Canada taken into account as well), particularly in the Northwestern and Midwestern United States, than in Norway proper.

In terms of religion, Norwegians are traditionally Lutheran since the Reformation in Denmark–Norway and Holstein which made Lutheranism the only legal religion in the country, however large portions of the population are now either non-practicing, atheist, or agnostic. A significantly smaller part of the population of Norway are of other religions as well (belonging mostly to other Christian denominations such as the Norwegian Catholic Church).
