As Wikipedia puts it (well of course!):
Norwegian in its two forms, Bokmål and Nynorsk, is the main national official language of all of Norway. Sámi, a group which includes three separate languages, is recognised as a minority language on the national level and is a co-official language alongside Norwegian in the Sámi administrative linguistic area (Forvaltningsområdet for samisk språk) in Northern Norway. Kven is a minority language and is a co-official language alongside Norwegian in one municipality, also in Northern Norway.
Norwegian, actually Bokmål was the second translation of the CORE-OM. A translation into Sámi was started but never finished sadly. There were jokes (as the translation work was done in Northern Norway, in Tromsø, and Nynorsk is more used in the north of Norway than the south) about getting a translation into Nynorsk but Nynorsk and Bokmål are completely mutually intelligible and Bokmål somewhat more used across the whole of Norway.
