Finland has applied for NATO membership

Finland’s security environment was fundamentally altered when Russia launched its invasion of Ukraine in February 2022. Based on a reassessment of the security policy situation following this development, Finland has applied for NATO membership. The NATO member countries signed the Accession Protocol concerning Finland's NATO membership at NATO Headquarters in Brussels on 5 July, making Finland an invitee of the Alliance. Finland’s NATO membership must be ratified in each member country.

NATO membership will strengthen Finland’s security in the changed security environment and improve stability and security in the Baltic Sea region and Northern Europe. Finland’s strong defence capability and resilience to crisis will also strengthen NATO and the collective defence of the Alliance.

As a member of NATO, Finland will be part of NATO’s collective defence and decision making and, thus, be covered by the security guarantees enshrined in Article 5 of the Treaty.
