Norse Kingdom Name Generator

Before Harald Fairhair united Norway it held petty kingdoms such as Vestfold, Hörðaland, Rogaland, Hálogaland, Raumaríki, Hringaríki, Agðir and Þrándheimr. The Danes held Jótland, Selund and Skáney with a legendary seat at Hleiðra; the Svear held Svealand and Uppland; Norse settlers founded Garðaríki in the east, Jórvík and Dyflin in the west, and the island realms of Orkneyjar and Suðreyjar.

The sources never list them in one place, but the usual count is Ásgarðr (the gods), Vanaheimr (the Vanir), Álfheimr (light elves), Miðgarðr (humans), Jötunheimr (giants), Svartálfaheimr or Niðavellir (dwarves), Niflheimr (ice and mist), Múspellsheimr (fire) and Hel (the dead). Halls inside them such as Valhöll, Glaðsheimr and Fólkvangr also work as realm names.

Combine a single concrete first element with a real Old Norse land word. Animals (úlfr, hrafn, björn), metals (járn, gull), weather (frost, hrím, vindr), gods (Þórr, Óðinn, Freyr) and founders (Haraldr, Ketill) all work. Endings: -ríki (realm), -land, -heimr (home), -mörk (march), -fold (plain), -garðr (stronghold), -vellir (fields), -ey (island). Hrafnsríki and Ketilsvellir follow the same logic as Raumaríki and Þingvellir.

Yes. The historical and mythological names are public knowledge and the invented ones are free to use. For Crusader Kings, Bannerlord, Valheim servers or anything with limited fonts, choose the plain forms such as Skjoldgard, Ravnheim or Kingdom of Hrafnsey; save the ð, þ and ö spellings for printed lore.
