Vikings did not have surnames the way we do. A person was a given name first, and then a second name that placed them: whose child they were, what they had done, or where they held land. Get those two halves right and a Norse name feels lived-in rather than dressed up, whether it belongs to a saga hero or a raider with three lines in your campaign.

Open the Viking name generatorThe given name
Old Norse given names are built from hard, concrete words: animals, gods, iron and battle. Bjorn is bear, Ulf is wolf, the element Sig means victory and Thor lends his name to many more. They are short and stressed on the first beat, which is why Ragnar, Sigurd and Astrid all sound decisive. When you choose, say it aloud: if it lands heavy and quick, it fits.
Patronymics: -sson and -sdottir
The most common second name was a patronymic, the father's given name with an ending: -sson for a son, -sdottir for a daughter. So the children of Eirik are Bjorn Eiriksson and Astrid Eiriksdottir, and the children of Harald are Olaf Haraldsson and Gyda Haraldsdottir. This is the single most important detail for an authentic Norse name, and it is gendered, so it should always match the character. Matronymics, formed from the mother's name, existed too but were rarer.
Bynames: the earned nickname
Alongside or instead of a patronymic, many Vikings carried a byname, a nickname that did the job a surname does now. Some honoured a deed or a virtue (the Bold, the Wise, Fairhair), some were blunt about looks or temper (the Red, the Grim, Bloodaxe), and some recorded a famous journey (the Far-Travelled). Bynames are the most characterful part of a Norse name and the most fun to choose, because a single word tells you the whole reputation.
Letting a generator do the work
Norse names combine naturally from a given name and a second name, which is how the Viking name generator builds them, with options for gender, length and which second-name form to use, plus save and refine. Generate a batch, read them aloud, and keep the ones that sound like they would answer to them across a mead hall. For the broader principles, see the guide on how to name a fantasy character.
A few pitfalls
- The wrong patronymic ending. A daughter is -sdottir, not -sson. Mixing them is the giveaway of a name that has not been checked.
- Too many soft sounds. Flowing, vowel-heavy names belong to other traditions; Norse names stay hard and clipped.
- Byname overload. One earned nickname is striking; stacking three reads as parody. Pick the one that matters.
If your Viking shares a world with others, that hard, weather-worn sound is a strong contrast to the cosy names of your halflings and sits comfortably beside the stout names of your dwarves.
