United Nations Day on 24 October 2025 marks the 80th anniversary of the entry into force in 1945 of the UN Charter.

With the ratification of this founding document by the majority of its signatories, including the five permanent members of the Security Council, the United Nations officially came into being.

Eighty years after its founding, the United Nations faces new challenges. The Organization is working on ways to adapt and strengthen itself. With the Agenda 2030, the Pact for the Future, and the UN80 initiative, the UN is looking to renew the foundations of international cooperation, and to ensure that it can deliver for people everywhere.

There is no other global organization with the legitimacy, convening power and normative impact of the United Nations. No other global organization gives hope to so many people for a better world and can deliver the future we want. Today, the urgency for all countries to come together, to fulfil the promise of the nations united, has rarely been greater.

UN Day, celebrated every year, offers the opportunity to amplify our common agenda and reaffirm the purposes and principles of the UN Charter that have guided us for the past 80 years.
