The Food and Agriculture Organization (FAO) is a specialized agency of the United Nations that leads international efforts to defeat hunger and improve nutrition and food security globally.

FAO was established on October 16, 1945, in Quebec City, Canada.
Initially, its temporary headquarters were located in Washington, D.C., USA.

Canberra (Australia), Hyderabad (India), and New York (USA) serve other distinct administrative or regional functions but do not house the primary global headquarters of the FAO.
