List of specialized agencies of the United Nations

Specialized agencies are autonomous organizations working with the United Nations and each other through the coordinating machinery of the United Nations Economic and Social Council at the intergovernmental level, and through the Chief Executives Board for coordination (CEB) at the inter-secretariat level. Specialized agencies may or may not have been originally created by the United Nations, but they are incorporated into the United Nations System by the United Nations Economic and Social Council acting under Articles 57 and 63 of the United Nations Charter. At present the UN has in total 15 specialized agencies that carry out various functions on behalf of the UN. The specialized agencies are listed below.

The Food and Agriculture Organization of the United Nations leads international efforts to defeat hunger. Serving both developed and developing countries, FAO acts as a neutral forum where all nations meet as equals to negotiate agreements and debate policy. FAO's mandate is to raise levels of nutrition, improve agricultural productivity, better the lives of rural populations and contribute to the growth of the world economy. FAO is the largest of UN agencies and its headquarters is in Rome, Italy.

The International Civil Aviation Organization (ICAO) was founded in 1947. It codifies the principles and techniques of international air navigation and fosters the planning and development of international air transport to ensure safe and orderly growth. Its headquarters are located in the Quartier international de Montréal of Montreal, Canada.

The ICAO Council adopts standards and recommended practices concerning air navigation, prevention of unlawful interference, and facilitation of border-crossing procedures for international civil aviation. In addition, ICAO defines the protocols for air accident investigation followed by transport safety authorities in countries signatory to the Convention on International Civil Aviation, commonly known as the Chicago Convention.
