Viking & Norse Baby Names: Legal Guide for Modern Scandinavia
A 1,000-year-old name register, brought up to date. This guide covers every major Viking and Old Norse name still legally registrable today in Iceland, Norway, Denmark and Sweden — with meanings, mythological background, and the exact spelling each country accepts.
Are Viking names still legal?
Yes — and in much of Scandinavia, they are actively encouraged. Iceland\'s Mannanafnaskrá (the official approved-name register) is built around the Old Norse naming tradition. Norway, Denmark and Sweden each maintain more permissive systems but still favour classical names from the sagas, the Eddas, and Viking-era kings and queens.
The core requirement is grammatical fit. Iceland enforces this strictly — every name must have a genitive form and use only the Icelandic alphabet. Norway and Denmark are more flexible, but reject names that could harm or ridicule a child. Sweden\'s 2016 Personal Names Act made nearly all traditional Norse names automatically valid.

Country-by-country legal status
Each Nordic country handles Norse heritage names differently. Here is what to expect when you register at the local civil office.
🇮🇸 Iceland — Mannanafnanefnd (the Naming Committee)
Iceland is the gold standard for Norse names. Almost every Old Norse name is on the official Mannanafnaskrá register. The catch: spelling must follow Icelandic grammar. Foreign forms (Thor, Odin, Magnus) require Icelandic-grammar variants (Þór, Óðinn, Magnús). The committee reviews unusual cases within 4–12 weeks. Read more: Baby Name Laws in Iceland.
🇳🇴 Norway — Skatteetaten / Folkeregisteret
Norway\'s 2002 reform made the system permissive: any well-established personal name is accepted. Mythological names (Odin, Thor, Frey, Freya, Loki, Idun) are all approved without special review. Saga names (Olav, Harald, Sigrid, Ragnhild) are central to Norwegian identity and remain top-30 today.
🇩🇰 Denmark — Familieretshuset
Denmark maintains an approved-list system (~33,000 names). Most Norse names are on it. New entries are reviewed by the Agency of Family Law. The Danish royal family\'s use of names like Vincent, Athena and Isabella shifts public taste, but classics (Sven, Knud, Astrid, Freja) hold their ground.
🇸🇪 Sweden — Skatteverket
Sweden\'s 2016 Personal Names Act removed most historic restrictions. Old Norse names are unconditionally accepted. Vintage Swedish-Norse names (Astrid, Folke, Nils, Sigge, Tora) are seeing a strong revival, often making the national top-100. Read more: Baby Name Laws in Sweden.
Names that need adaptation in Iceland
The Icelandic alphabet has no C, Q, W or Z, and every name must have a genitive (possessive) form. Common adaptations the Mannanafnanefnd has approved include:
- Lucas → Lúkas (replaces "c" with "k")
- Christine → Kristín
- Alexander → Alexsandr (rare; usually requires individual application)
- Wilhelm → Vilhjálmur

Frequently asked questions
Are Viking names legal to use today in Scandinavia?
Yes. Most traditional Old Norse names are explicitly approved across Iceland, Norway, Denmark and Sweden. Iceland in particular celebrates them — they form the backbone of the Mannanafnaskrá approved-name register. Some require minor spelling adaptation to fit modern grammar.
Can I name my child Thor or Odin?
Yes — both are accepted in Norway, Denmark and Sweden. In Iceland the standard Icelandic spellings Þór and Óðinn are required.
Which Nordic country is strictest about Viking names?
Iceland is the strictest, but paradoxically also the most welcoming of authentic Old Norse names. The Mannanafnanefnd committee requires every name to fit Icelandic grammar — most Viking names already do.
Are Viking goddess names like Freya allowed?
Yes. Freya (Freja in Denmark, Freyja in Iceland and Norway) is one of the most popular girl names across all four Nordic countries today.
What about Loki?
Loki has been approved in Iceland and is registrable in Norway and Sweden. Denmark approved it as a boy\'s name in 2015 after a public review.
