Northwest Model United Nations (NWMUN) was founded as a collegiate conference by Model United Nations at the University of Washington (UW-MUN) in November 2007. From the start, NWMUN was focused on being collaborative - not insular to any school, but rather run by and for the entire Model United Nations community in the Pacific Northwest. To that end, in 2008-2009, the conference was separated from the UW Model United Nations team and managed by a new nonprofit, the Northwest Association for Global Affairs (NWA). In 2014, the NWMUN program expanded with the creation of a second collegiate conference, Northwest Model United Nations - Portland, which is held annually in February. The original conference was renamed Northwest Model United Nations - Seattle.

In late 2019, the NWA Board of Directors launched Northwest Model United Nations - High School, with it scheduled to be held for the first time in May 2020. Due to the COVID-19 pandemic and its economic effects, the conference was unable to be held for four additional years. The conference is being held for the first time in May 2024.

On this page will be links to old information once the NWMUN-HS conference has been held for at least two years. Our nonprofit archives all of our old conference websites, as a service we provide for Model UN teams who have attended the conference in the past. We encourage teams to develop their own institutional memory internally, but we also keep our websites up to enable teams to consult them for past NWMUN attendance, country assignments, awards, committees, topics, and staff members.
