The Economic and Social Council, ECOSOC, is a subsidiary organ of the United Nations which undertakes the responsibility of the direction and coordination of the economic, social, humanitarian, and cultural activities carried out by the UN.

ECOSOC is one of the largest bodies of the UN, hosting 54 members since being established by the UN charter in 1945. The primary mission of this committee is to further sustainable development on economic and social issues including humanitarian pursuits. The ECOSOC acts largely as a key advisory body to the UN, and is mandated to promote higher standards of living, full employment, and economic and social progress.
