Finland is applying 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.

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

Through NATO membership, Finland would be a part of NATO's collective defence and, thus, would be covered by the security guarantees enshrined in Article 5 of the Treaty. As a member of NATO, Finland would participate in making decisions on security policy issues that are of key importance to Finland.
