Icelandic citizens aged 18 and over on referendum day will be eligible to vote in Iceland’s EU referendum, currently expected in 2026. Permanent residents who hold Icelandic citizenship qualify, but foreign nationals — even long-term residents — do not have the right to vote in this national poll.
Key takeaways
- Only Icelandic citizens aged 18 or older can vote in the EU referendum.
- Foreign nationals and permanent residents without citizenship are excluded, regardless of how long they have lived in Iceland.
- Icelanders living abroad may be eligible to vote if they remain on the national register — exact rules are still being confirmed.
- The Alþingi (Iceland’s parliament) must formally approve the referendum date and final voting rules before polling day.
The question of EU membership has circled Icelandic politics for decades. Iceland applied to join the EU in 2009, froze negotiations in 2013, and formally withdrew the application in 2015 — but the conversation never fully stopped. Now, with the Alþingi moving toward a consultative referendum, the eligibility rules matter more than ever to the roughly 390,000 people who call Iceland home.
Iceland’s electorate for national votes is defined by citizenship, not residency. This is a meaningful distinction because Iceland has a significant immigrant population — around 15–16% of residents were born abroad. Many of those people pay taxes, speak Icelandic, and have built lives here in Reykjavík or further afield in places like Akureyri or the Westfjords, but they will have no say in a decision that directly affects their future here. It is a point of genuine tension in the public debate.
Who exactly qualifies to vote in Iceland’s EU referendum?
To vote, a person must be an Icelandic citizen and have reached the age of 18 by referendum day. Dual citizens — people who hold Icelandic citizenship alongside another nationality — qualify fully. Iceland has allowed dual citizenship since 2003, so this covers a meaningful slice of the diaspora and of naturalised residents who went through the citizenship process.
Icelanders living abroad are a more complex case. For general Alþingi elections, overseas Icelanders can vote if they are registered in the national population registry (þjóðskrá) and have not been removed from it after an extended absence. Whether identical rules will apply to the referendum has not been finalised at the time of writing, and the Alþingi is expected to set this out in the referendum legislation. If you are an Icelander living abroad and this affects you, watch the official Þjóðskrá Íslands announcements closely as the date approaches.
Nordic citizens who live in Iceland can vote in municipal elections here — a right extended across the Nordic region — but that privilege does not extend to national referendums or Alþingi elections. So a Danish or Norwegian citizen settled in Reykjavík for twenty years still cannot vote on the EU question. The same applies to EEA citizens from elsewhere in Europe.
Naturalisation is the one route for non-citizens. Iceland’s naturalisation process typically requires at least seven years of continuous legal residence, language ability, and a clean criminal record, among other conditions. Anyone who has already naturalised is fully enfranchised for the referendum.
Frequently asked questions
Can EU citizens living in Iceland vote in the EU referendum?
No. EU citizens who are residents in Iceland — including citizens of all 27 EU member states — cannot vote in Iceland’s national referendum. Only Icelandic citizens aged 18 and over are eligible. Residency, even long-term residency, does not grant this right.
Can Icelanders living abroad vote in the EU referendum?
Potentially yes, but the final rules depend on referendum legislation still being drafted by the Alþingi. For standard Alþingi elections, overseas Icelanders can vote if they remain on the þjóðskrá (national population registry). It is safest to check your registration status well before the referendum date is confirmed.
When will Iceland’s EU referendum actually take place?
The referendum is widely discussed as a 2026 event, but no binding date has been set at the time of writing. The Alþingi must pass referendum legislation first, and political negotiations around the exact wording and timing are ongoing. Follow Alþingi announcements for the official schedule.
