Banned Baby Names in Europe

European naming laws range from extremely permissive (the UK, Ireland, the Netherlands) to highly regulated (Iceland, Denmark, Germany, France historically). The differences reflect deep cultural beliefs about the role of the state, the meaning of identity, and the protection of children from parental whim.

This article is a general overview, accurate to the best of our knowledge at time of writing. It is not legal advice. Naming laws across Europe differ sharply between countries and are updated periodically. For authoritative guidance, speak to a family lawyer or the civil registry office in your country.

The strict end: Iceland

Iceland has a National Naming Committee that maintains an approved list of around 4,000 names (split by gender). Any name outside the list must be submitted for approval, and the committee considers whether the name fits Icelandic grammar, whether it can be declined in the Icelandic case system, and whether it would be embarrassing for the child. Names are regularly refused.

Famous cases: 'Blær' (meaning 'light breeze') was refused for a girl because it was classified as masculine; the family won after a court challenge in 2013. 'Duncan' was refused because it could not be inflected in Icelandic grammar.

Denmark

Denmark maintains a list of approximately 7,000 approved names. Parents choosing a name not on the list must apply to the Ministry of Ecclesiastical Affairs, which rules on whether the name is appropriate. The government rejects around 1,000 names per year. Rejections include names that are surnames, unusual spellings of existing names, and names with inappropriate meanings.

Germany

Germany's rules are about gender clarity and child welfare. A name must clearly indicate gender (some unisex names require a second, gendered middle name), must not be a product or brand name, and must not ridicule the child. Local registrars have final say. Rejections include 'Stompie' (unclear gender), 'Osama bin Laden' (potential harm to child), and 'Adolf Hitler' (obvious reasons).

France

France liberalised its naming laws in 1993, abolishing the old rule that required names to come from a saints' calendar. Now almost any name is accepted, but registrars can still refuse names they consider contrary to the child's best interests. Rejections are rare but happen; 'Nutella' was famously refused in 2015 for a girl, and the court renamed her 'Ella'.

The permissive end: UK, Ireland, Netherlands

The UK has no approved list and essentially no veto power over names, with a handful of common-sense exceptions (obscenity, numerals, names containing symbols). Ireland and the Netherlands operate similarly. The UK's General Register Office will query a name but rarely refuses it outright.

The pattern across Europe is clear: countries where the state plays a larger role in daily life tend to regulate names more strictly; countries where individual freedom is prized tend to let almost anything through.

Why the differences exist

The strict-list countries tend to share two features: a small population (Iceland: 380,000) where names function partly as public infrastructure, and a grammatical case system that requires names to be inflectable. The permissive countries tend to have larger populations and simpler grammar.

There is also a cultural dimension. France, Germany, and the Scandinavian countries all place a higher legal weight on the 'best interests of the child' than the UK or Ireland, and naming is one of the areas where that weight is expressed.

For parents moving across borders

If you are likely to move between countries, check the rules in your destination before registering the birth. A name that is valid in the UK may be blocked in Denmark; a Danish name may be misfiled in a UK registry if it contains diacritics. Our guide to registering a baby name covers the UK process in detail; for other countries, check the civil registry office in the country of birth.
