The Oslo Forum is a series of retreats for international conflict mediators, high-level decision-makers and other actors in the peace process. It provides a discrete and informal space to reflect on current mediation practices, collaborate across institutional and conceptual divides and advance negotiations.

After an initial gathering of mediators in 2003, the Oslo Forum has become the venue of choice for international peacemaking. Past participants in the Oslo Forum include : Jimmy Carter, Kofi Annan, Federica Mogherini, John F. Kerry, Mohammad Javad Zarif, Juan Manuel Santos, Fatou Bensouda, Thabo Mbeki, Martti Ahtisaari, Rodrigo Londoño (Timoleón Jiménez) and Catherine Ashton. The Oslo Forum is proud to have hosted several Nobel Peace Prize laureates.
