Mohammad Mosaddegh was an Iranian politician, author, and lawyer who served as the 30th Prime Minister of Iran from 1951 to 1953, elected by the 16th Majlis. He was a member of the Iranian parliament from 1923, and served through a contentious 1952 election into the 17th Iranian Majlis, until his government was overthrown in the 1953 Iranian coup d'état aided by the intelligence agencies of the United Kingdom (MI6) and the United States (CIA), led by Kermit Roosevelt Jr. His National Front was suppressed from the 1954 election.

The prime minister of Iran was a political post that had existed in Iran (Persia) during much of the 20th century. It began in 1906 during the Qajar dynasty and into the start of the Pahlavi dynasty in 1923 and into the 1979 Iranian Revolution before being abolished in 1989.
