Arnor is a fictional kingdom in
J. R. R. Tolkien's writings. Arnor, or the Northern Kingdom, was a kingdom of the
Dúnedain in the land of
Eriador in
Middle Earth. The name probably means "Land of the King", from
Sindarin Ara- (high, kingly) + (n)dor (land). Arnor is the territory of Middle-earth associated with the High Kings of the line of
Elendil, the kingship of which was restored at the crowning of Elessar (
Aragorn) after the
War of the Ring at the start of the
Fourth Age.
