Since 1945 and before, the League of Women Voters has been one of the leading supporters of the United Nations in the United States. The League has official NGO (Nongovernmental Organization) status at the UN and is represented by two official UN Observers. Among other duties, the League's UN Observers update LWV members and the public through the year about UN activities.

The Global Democracy Program is the League of Women Voters’ program for activists and nongovernmental organizations worldwide. Working with groups abroad to increase their voice in stressing transparency, accountability, and good governance in their societies, the League assists in expanding community influence in public policy-making processes while helping citizens build leadership skills through interactive, hands-on training and citizen exchange programs. The League of Women Voters is registered as a Private Voluntary Organization with USAID and is part of the Registry of Civil Society Organizations with the Organization of American States.
