The United States Mission to the United Nations (USUN) serves as the United States delegation to the United Nations.^[1] USUN is responsible for carrying out the nation's participation in the world body. In 1947, the United States Mission was created by an act of Congress to assist the President and the Department of State in conducting United States policy at the United Nations. Since that time, USUN has served a vital role as the Department of State's UN branch. Today, USUN has approximately 150 people on staff who serve to represent the United States’ political, economic social, legal, military, public diplomacy, and management interests at the United Nations.

USUN is divided into the following sections: Executive; Washington; Political; Management and Reform; Economic and Social; Legal; Military Staff; Public Affairs; Host Country; Management; and Security.

The United States Mission to the United Nations is located at 799 United Nations Plaza (between East 44th and 45th streets on First Avenue) across the street from United Nations Headquarters.
