Hosein Alā (Persian: حسین علاء; 13 December 1881 – 13 July 1964) was an Iranian politician who served as Prime Minister in 1951 and from 1955 to 1957.

He was born in 1881 in Tehran and spent his early years in London. He was educated at Westminster School and studied law at the University of London after which he was admitted to the bar at Inner Temple. He became involved in politics through a position in the Foreign Affairs Ministry of Iran.^[2]

In his early political life Ala served as the chef de cabinet of the Iranian foreign ministry from 1905 to 1916. Subsequently, he was a member of an Iranian diplomatic delegation sent to the Paris Peace Conference of 1919. Despite the efforts of the delegation, led by Aliqoli Massoud Ansari, and assisted ably by Ala, the British government of the time nixed Iran's hopes of officially attending the diplomatic gathering. Moreover, with the Iranian Government in Tehran having recently negotiated the Anglo-Iranian Agreement it was decided that Ansari and Ala would be banished to foreign legations to ensure they would not act as lightning rods against the agreement. Ala was appointed as the Iranian diplomatic envoy to Spain in 1920. Shortly thereafter Ala was appointed as Iran's lead diplomat in Washington where he attempted to interest American oil companies to agree to invest in Iran, to undercut the monopoly of the Anglo-Persian Oil Company.^{[citation needed]}

He then became a member of parliament and was among the opposition to the fall of the Qajar dynasty during the Shah Pahlavi transition.^{[citation needed]}

He was the governor of Bank Melli Iran from 1933 to 1934 and from 1941 to 1942.^[3] From 1934 to 1936, Alā was ambassador to the United Kingdom.^[4] Alā was Iranian Ambassador to the United States from 1946 to 1950.

He was elected Prime Minister by parliament following the assassination of Haj Ali Razmara in 1951. His premiership, however, was not to last long, and he resigned on 27 April after Mohammad Mosaddegh had submitted another oil nationalisation bill to parliament two days earlier. The issue of nationalisation was highly contentious, and Alā did not want to appear to oppose it.^[5] During his brief administration, the term of service of members of parliament was increased from 2 to 4 years. He was later appointed as Court Minister, remaining one until his death.

Alā was appointed Prime Minister for the second time in 1955, and in November 1955 survived an assassination attempt at the funeral of a son of Abol-Ghasem Kashani.^[6] He was replaced in April 1957 after an upsetting international incident involving the murder of three Americans by outlaw Ahmad Shah and his gang.^[7]

In 1963 the protests led by religious figures intensified in Iran due to the policies of the Shah, Mohammad Reza Pahlavi.^[8] Mohammad Ali Varasteh, Abdollah Entezam and Ala personally expressed their concerns about Shah's policies and their potential results which made all of them outsiders in the court of the Shah.^[8] In addition, Ala' and Entezam were dismissed from the Iranian Senate to which they had just appointed.^[8]

Alā died of pneumonia on 13 July 1964 at the age of 82.^[9] He left a son and a daughter, and was survived by his wife, who died in 1981. His son, Fereydoun Ala, was the founding director of the National Iranian Blood Transfusion Service and is honorary president of the Iranian Comprehensive Haemophilia Care Center. His daughter, Irān, is married to Eskandar Firouz, the noted authority on Iranian fauna and environmental topics.
