Geneva International Model United Nations (GIMUN) is a non-governmental organisation with special consultative status with the Economic and Social Council of the United Nations based in Geneva. Run entirely by students, its aim is to promote the ideals and principles of the United Nations by giving students the chance to participate in educational events.

The General Assembly is the most important organ of the NGO. Besides the General Assembly, GIMUN is led by the Executive Board. The Executive Board is supported by the Advisory Board and by the working groups for the departments.
