Nasrollah Entezam (Persian: نصرالله انتظام; also spelled Naṣr-Allāh Enteẓām; 16 February 1900 – 19 December 1980) was a diplomat, politician, and minister, as well as Iranian Ambassador to the United States and France.

[1][5][4][8] In 1918, following World War I, Entezam joined the Ministry of Foreign Affairs before serving as the Secretary to the Iranian Legations in Paris, Warsaw, Bern, and London between 1926 and 1929.

[2][1] During the Anglo-Persian Oil Company dispute in 1932-1933, Entezam served as secretary to the Iranian delegation and accompanied Ali-Akbar Davar and Hossein Ala' to Geneva to present Iran's case at the League of Nations.

[10][11] He continued in foreign affairs following the war by representing Iran at the San Francisco Conference in 1945, the gathering that established the United Nations, and at the first session of the General Assembly in 1946.

[3][2][1][4] The Korean War occurred during his presidency and Entezam, wanting both economic aid from the USA and improved relations with Russia, strove to "tread a delicate path while maintaining a judicious appearance of fairness to all.

[14] He was the first non-Christian diplomat at the General Assembly in New York and served as Iran ambassador to the United States until 1952, when he was removed and replaced by Allah-Yar Saleh under Prime Minister Mohammad Mosaddegh.

[7] According to a 1963 report by the United States Embassy, Entezam and his brother Abdollah were informally active in Prime Minister Amini's Cabinet and met every Wednesday for twelve years.

[citation needed] Several years later, following the Islamic Revolution, he returned to Iran from asthma treatment in Switzerland despite his family's pleas to stay abroad.
