Attend HalcyonMUN

HalcyonMUN XIV will take place on 25–26 February 2027 at Halcyon London International School, in the heart of central London.

Over two days, delegates will represent countries, debate urgent global issues, draft resolutions, build alliances, and develop the confidence to speak on complex international questions. Whether you are an experienced delegate, attending your first conference, applying as a Student Officer, or bringing a school delegation, HalcyonMUN is designed to be academically rigorous, accessible, and rewarding.

HalcyonMUN is Central London’s biggest (and best) Model UN conference, but we’re more than that. We’re a cohort of passionate students who care deeply about global diplomacy and who understand the importance of Model UN conferences in today’s world. On top of that, we know how fun MUN conferences can be, which is why we strive to create the best events that embody everything we know and love about Model UN.

Every year, over 200 students from across the city come together to participate in our two events, COP and HLISMUN. And we work closely with affiliated schools and student organizations to provide opportunities to underprivileged students who might otherwise not have the opportunity to participate in conferences such as ours. We believe that every student should be allowed to practice the essential skill of global diplomacy, especially in the current political climate, where the need for good leadership has become increasingly relevant.

If you’re new to MUN, we recommend reading the UN guide on what Model UN is.
