The United Nations Association of the United States of America (UNA-USA) is a center for innovative programs to engage Americans in issues of global concern, from education and HIV/AIDS to peace, security and international law. Its educational and humanitarian campaigns, including teaching students in urban schools, clearing minefields and providing school-based support for children living in HIV/AIDS-affected communities in Africa, allow people to make a global impact at the local level. A not-for-profit organization, UNA-USA encourages strong United States leadership in the United Nations and is a part of the World Federation of United Nations Associations.

Mission
"The United Nations Association of the United States of America is dedicated to educating, inspiring and mobilizing Americans to support the principles and vital work of the United Nations, strengthening the United Nations system, promoting constructive United States leadership in that system, and achievement of the goals of the UN Charter."
