The Commission on Narcotic Drugs (CND) is one of the functional commissions of the United Nations' Economic and Social Council (ECOSOC), and is the central drug policy-making body within the United Nations System. The CND also has important mandates under the three international drug control conventions, alongside the three other treaty-mandated bodies: United Nations Office on Drugs and Crime, World Health Organization, and International Narcotics Control Board.

The United Nations Economic and Social Council (ECOSOC) is one of the six principal organs of the United Nations, responsible for coordinating the economic and social fields of the organization, specifically in regards to the fifteen specialized agencies, the eight functional commissions, and the five regional commissions under its jurisdiction.
