Norse Last Name Generator

Vikings did not have family surnames. A Norse last name was either a patronymic, built from the father's name plus -son or -dóttir (Eiríksson, Sigurðardóttir), or a byname earned for a trait, a deed, or a place: Haraldr Hárfagri (Fairhair), Eiríkr Blóðøx (Bloodaxe), Ketill Flatnefr (Flatnose), Ívarr inn Beinlausi (the Boneless). This generator gives you all three layers, so you can name a character the way a saga would, or the way a Scandinavian census would centuries later.

The patronymics here use the genitive stem the way Old Norse and modern Icelandic do, which is why it is Hákonarson rather than Hakonson and Sigurðardóttir rather than Sigurdsdottir; anglicized spellings are included so they are easy to type. Bynames appear both in Old Norse (Hardrada, Tjuguskegg, Hausakljufr) and in plain English (Hardruler, Forkbeard, Skullsplitter), since sagas in translation use either. The final group is what Norse naming turned into: Danish and Norwegian -sen names, Swedish -sson and nature compounds like Lindqvist and Bergström, and Norwegian farm names such as Haugen, Bjørnstad and Solheim that became hereditary in the 1800s.

For a Viking-age character, pair a patronymic with a byname (Ulf Ketilsson Greycloak). For a modern Nordic character, a single farm or nature surname is the authentic choice.
