The Organization of American States (OAS or OEA; Spanish: Organización de los Estados Americanos; Portuguese: Organização dos Estados Americanos; French: Organisation des États américains) is an international organization founded on 30 April 1948 to promote cooperation among its member states within the Americas.

Headquartered in Washington, D.C., United States, the OAS is a "multilateral regional body focused on human rights, electoral oversight, social and economic development, and security in the Western Hemisphere", according to the Council on Foreign Relations.[1] As of November 2023, 32 states in the Americas are OAS members.[2][3]

Luis Almagro of Uruguay was inaugurated as OAS secretary general in 2015.[4][5]
