An IGO is an organization composed primarily of sovereign states, or of other intergovernmental organizations. IGOs are established by treaty or other agreement that acts as a charter creating the group. Examples include the United Nations, the World Bank, or the European Union.

The United Nations Economic and Social Council (ECOSOC) defines an INGO as "any organization which is not established by inter-governmental agreement" (Resolution 288 (X) the 27th February 1950), "including organizations which accept members designated by government authorities, provided that such membership does not interfere with the free expression of views of the organizations" (Resolution 1296 (XLV) of 25th June 1968).
