The Group of 77 at the United Nations is a loose coalition of developing nations, designed to promote its members' collective economic interests and create an enhanced joint negotiating capacity in the United Nations. There were 77 founding members of the organization, but the organization has since expanded to 132 member countries. Practically speaking (as of 2011), the group can be described as comprising all of UN members (along with the Palestinian Authority) excluding the following:

Algeria holds the Chairmanship for 2012.

The group was founded on June 15, 1964 by the "Joint Declaration of the Seventy-Seven Countries" issued at the United Nations Conference on Trade and Development (UNCTAD). The first major meeting was in Algiers in 1967, where the Charter of Algiers was adopted and the basis for permanent institutional structures was begun. There are Chapters of the Group of 77 in Rome (FAO), Vienna (UNIDO), Paris (UNESCO), Nairobi (UNEP) and the Group of 24 in Washington, D.C. (International Monetary Fund and World Bank).
