The UN Association of Finland is a national association with member organisations.

According to the statutes, the executive committee can approve

1. members that are local, registered UN associations and any incorporated societies in Finland that share the goals of the UN Association of Finland
2. individual members that are Finnish nationals or nationals of other countries residing permanently in Finland, who share and approve the goals and statutes of the UN Association of Finland
3. passive members that are incorporated societies or individuals wishing to support the purposes and activities of the organisation financially

Local UN associations provide people with direct possibilites for local action. The UN Association has five active local UN associations: in Helsinki, Turku, Tampere, Oulu and Jyväskylä.

The activities of a local UN association may vary. What they do have in common is the goal of making UN principles and goals known, hence promoting international understanding and peaceful cooperation.

Activities of a local UN association may include organising study groups, seminars and discussions, making field trips and excursions and taking part in different campaigns by organising a local event.

The UN Association of Finland cooperates with its local UN associations by e.g. providing training and coordinating campaigns.
