Is Denmark in the EU? Full Membership, Euro Opt-Out, Schengen

For a country that has been at the heart of European trade and diplomacy for centuries, Denmark’s relationship with the European Union is surprisingly selective. It’s a full member, yet it doesn’t use the euro, and it carved out special exceptions on justice and home affairs. This guide clears up exactly where Denmark stands in the EU, why it keeps the krone, and what its opt-outs really mean.

EU membership year: 1973 ·
Schengen area member since: 2001 ·
GDP per capita (EUR): 47,800 ·

The table below summarizes Denmark’s key EU attributes.

Is Denmark a part of the European Union?

Yes, Denmark is a full member state of the European Union. It joined on 1 January 1973, along with Ireland and the United Kingdom, as part of the first enlargement of the European Economic Community (European Union – Denmark country profile). Denmark participates in the EU’s single market, customs union, and most policy areas — but with a twist. It negotiated opt-outs from the euro and certain justice and home affairs policies after Danish voters rejected the Maastricht Treaty in 1992 (Wikipedia – Danish opt-outs from the European Union).

When did Denmark join the EU?

• Denmark joined the European Economic Community (EEC), the predecessor to the EU, on 1 January 1973 (European Union – Denmark country profile).
• The accession meant Denmark adopted all EEC treaties, including the common agricultural and trade policies.
• Denmark held a second referendum in 1993 that ratified the Maastricht Treaty, but only after securing opt-outs via the Edinburgh Agreement (Wikipedia – Danish opt-outs from the European Union).

What is Denmark’s status in the EU?

Denmark is a full member with the same voting rights and obligations as other member states. Its population of approximately 5.99 million people and national capital Copenhagen are represented in the European Parliament and the Council of the EU (European Union – Denmark country profile).

The implication: Denmark’s EU status is not a simple yes/no. It is a full member, but its opt-outs create a tiered relationship that makes it, in practice, a participant in some areas and an observer in others.

Does Denmark use the euro?

No. Denmark’s official currency is the Danish krone (DKK), and the country is not obliged to adopt the euro (European Union – Denmark country profile). The Danish krone is pegged to the euro through the Exchange Rate Mechanism II (ERM II), with a narrow fluctuation band of ±2.25% (Wikipedia – Denmark and the euro). This means the krone’s value is closely aligned with the euro, but it remains a distinct currency.

Why does Denmark not use the euro?

• The primary reason is the Edinburgh Agreement of 1992, which granted Denmark a formal opt-out from the euro (European Union – Denmark country profile).
• In a 2000 referendum, Danish voters rejected adopting the euro by 53.2% to 46.8% on a turnout of 87.6% (Wikipedia – Denmark and the euro).
• Public opinion in Denmark has consistently shown a slight majority in favour of keeping the krone; no new referendum is scheduled.

Do businesses accept euros in Denmark?

Generally, no. Most businesses in Denmark accept only Danish kroner for cash transactions. Some larger hotels, airports, and tourist shops may accept euros, but at unfavourable exchange rates. Visitors are advised to exchange currency or use a card that handles the conversion (European Union – Denmark country profile).

The pattern: Denmark chose to maintain monetary sovereignty in name, but the narrow ERM II band leaves little room for independent interest rate policy.

Which EU countries do not use the euro?

Seven EU countries do not use the euro as their official currency: Bulgaria, Croatia, Czech Republic, Denmark, Hungary, Poland, and Romania. Denmark is unique among them because it has a formal opt-out; the others are legally required to adopt the euro once they meet the convergence criteria (European Union – Denmark country profile).

How many EU countries have opted out of the euro?

Only one EU country — Denmark — has a formal opt-out from the euro. The United Kingdom also had an opt-out while it was a member, but since Brexit that no longer applies. The other non-euro EU members are bound by treaty to join eventually (Wikipedia – Denmark and the euro).

Which EU members are legally required to join the euro?

All EU member states except Denmark and the former UK are legally obligated to adopt the euro once they meet the Maastricht convergence criteria — including price stability, sound public finances, exchange rate stability, and low long-term interest rates. Bulgaria, for example, is in the process of joining, while Poland and the Czech Republic have delayed their timelines indefinitely (Wikipedia – Denmark and the euro).

The catch: Denmark’s opt-out makes it the only EU member that can freely choose whether to join the euro, a position that creates a useful case study for debates about differentiated integration in the EU.

What is Denmark’s relationship with the Schengen area?

Denmark has been a member of the Schengen area since 25 March 2001 (European Union – Denmark country profile). Schengen membership is separate from EU membership; not all EU countries are Schengen members (e.g., Ireland), and some non-EU countries (Iceland, Norway, Switzerland, Liechtenstein) are part of Schengen.

Is Denmark a Schengen member?

Yes. Denmark applies all Schengen rules, including passport-free travel across internal borders, common visa policy, and police and judicial cooperation in cross-border crime. Denmark retains the right to reintroduce temporary border controls under certain conditions, such as during security threats or public health emergencies (European Union – Denmark country profile).

What countries are in the Schengen area?

The Schengen area comprises 27 countries: 23 of the 27 EU member states plus Iceland, Norway, Switzerland, and Liechtenstein. Denmark’s participation means travellers can enter Denmark from another Schengen country without a passport check (European Union – Denmark country profile).

Why this matters: Schengen membership makes Denmark fully integrated into the EU’s internal border-free zone, even while it sits out the euro. That’s a reminder that EU cooperation is multi-layered.

How does Denmark compare to other EU members?

Denmark is one of the wealthiest EU member states. Its GDP per capita of EUR 47,800 places it fourth in the EU, behind Luxembourg, Ireland, and the Netherlands (European Union – Denmark country profile). It contributes 2.2% of total EU GDP despite having only 1.1% of the EU population.

What is the poorest country in Europe?

By GDP per capita, Ukraine is often cited as the poorest country in Europe if considering the wider geographical continent. Within the EU, Bulgaria and Romania have the lowest GDP per capita. Denmark, by contrast, ranks among the top five EU economies by this measure.

What are the 51 countries in Europe?

Geographically, Europe comprises 51 countries (including transcontinental nations like Russia and Turkey). The European Union, however, has 27 member states. Denmark is one of those 27, making it simultaneously a small country by land area (42,925 km²) and a large one by economic influence (European Union – Denmark country profile).

The trade-off: Denmark’s wealth buys it influence in Brussels — but its opt-outs also prevent it from shaping the eurozone rules that indirectly affect its currency peg.

What are the latest developments in EU membership?

The most recent country to join the European Union is Croatia, which became the 27th member state on 1 July 2013. Several candidate countries — including Albania, Serbia, Turkey, Montenegro, and North Macedonia — are in various stages of accession negotiations.

When did the latest member join the EU?

Croatia joined on 1 July 2013. Since then, no new members have been added. EU enlargement continues to be a topic of debate, with the EU slow-walking accession for Western Balkan nations due to political and economic conditions (Wikipedia – Danish opt-outs from the European Union).

What is the 27th member of the European Union?

Croatia is the 27th member state. The UK’s departure in 2020 reduced membership from 28 to 27. Denmark remains a constant member, having joined in the first enlargement and stayed through every subsequent treaty negotiation.

Summary

Denmark’s relationship with the European Union is a masterclass in differentiated integration: full member of the club, selective participant in its deepest commitments. It sits at the table for every EU decision, yet keeps its own currency, chooses its level of involvement in justice policy, and only recently abolished its defence carve-out. For travellers, investors, or policymakers looking at the EU, the Danish example makes one thing clear: membership does not mean uniformity. The choice for Denmark’s government in the next decade will be whether its opt-out model remains a strategic advantage or becomes an obstacle to influencing the bloc’s future direction.

Danmark är fullvärdig medlem i EU sedan 1973 och ingår även i Schengenområdets medlemsländer, trots att man valt att stå utanför euron.
