The supreme leader of the Islamic Republic of Iran, officially styled as the leader of the Islamic Revolution or the leadership of the Islamic jurist by the Iranian Constitution, is the highest political and religious authority in Iran, taking precedence above the president who is the country's de jure head of state. The armed forces, judiciary, state radio and television, and other key government organizations such as the Guardian Council and Expediency Discernment Council are subject to the supreme leader."Who's in Charge?" by Ervand Abrahamian London Review of Books, 6 November 2008

According to articles 57 and 110 of the Iranian Constitution, the supreme leader supervises the activities of the legislative, judicial, and executive branches and delineates the general policies of the Islamic Republic. The second supreme leader, Ali Khamenei, issued decrees and made the final decisions on the economy, the environment, foreign policy, education, national planning, and other aspects of governance in Iran. Khamenei also made the final decisions on the amount of transparency in elections, and during his rule dismissed and reinstated presidential cabinet appointees.

The office was established by the Constitution of Iran in 1979, pursuant to Ayatollah Ruhollah Khomeini's concept of the Guardianship of the Islamic Jurist,Article 5, Iranian Constitution and is a lifetime appointment. Originally the constitution required the supreme leader to be Marja'-e taqlid, the highest-ranking cleric in the religious laws of Usuli Twelver Shia Islam; however, in 1989 the constitution was amended and simply asked for Islamic "scholarship" to allow the supreme leader to be a lower-ranking cleric.Moin, Baqer, Khomeini, (2001), p.293"Article 109 [Leadership Qualifications] (1) Following are the essential qualifications and conditions for the Leader: a. Scholarship, as required for performing the functions of the religious leader in different fields.

The style "Supreme Leader" () is commonly used as a sign of respect although the Constitution designates them simply as "Leader" ().

According to the constitution (Article 111), the Assembly of Experts is tasked with electing (following Ayatollah Khomeini), supervising, and dismissing the supreme leader. In practice, the Assembly has never been known to challenge or otherwise publicly oversee any of the supreme leader's decisions (all of its meetings and notes are strictly confidential)."Iran Announces Second Extension of Voting," Reuters, 23 October 1998. quoted in Members of the Assembly are elected by people in elections, and are approved by bodies (the Guardian Council) whose members are appointed by the supreme leader or appointed by an individual (Chief Justice of Iran) appointed by the supreme leader.

The United Nations list of Heads of State, Heads of Government, and Ministers for Foreign Affairs of all Member States lists the Iranian president as the official de jure head of state and government, rather than the supreme leader himself.

The Islamic Republic of Iran has in its history had three supreme leaders: Khomeini, who held the position from 1979 until his death in 1989; Ali Khamenei, who held the position from Khomeini's death until his assassination in 2026; and Khamenei's son Mojtaba Khamenei, who has held the position since 2026.

Requirements Since the 1989 amendments to the Constitution of Iran, any jurist of Islamic law can be elected Supreme Leader.

Incorporation in the constitution 1979 In March 1979, shortly after Ruhollah Khomeini's return from exile and the overthrow of Iran's monarchy, a national referendum was held throughout Iran with the question "Islamic Republic, yes or no?".Duality by Design: The Iranian Electoral System By Yasmin Alem Although some groups objected to the wording and choice and boycotted the referendum, 98% of those voting, voted "yes". Following this landslide victory, the constitution of Iran of 1906 was declared invalid. A new constitution for an Islamic state was created and ratified by referendum during the first week of December in 1979.

According to Francis Fukuyama, the 1979 constitution is a "hybrid" of "theocratic and democratic elements" with much of it based on the ideas Khomeini presented in his published book Islamic Government (Hukumat-e Islami). In the work, Khomeini argued that government must be run in accordance with traditional Islamic sharia, and for this to happen a leading Islamic jurist (faqih) must provide political "guardianship" (wilayat or velayat) over the people. The leading jurist were known as Marja'.

The Constitution stresses the importance of the clergy in government, with Article 4 stating that and the importance of the supreme leader. Article 5 states

Article 107 in the constitution mentions Khomeini by name and praises him as the most learned and talented leader for emulation (marja-i taqlid). The responsibilities of the supreme leader are vaguely stated in the constitution, thus any 'violation' by the supreme leader would be dismissed almost immediately. As the rest of the clergy governed affairs on a daily basis, the supreme leader is capable of mandating a new decision as per the concept of Vilayat-e Faqih.

The supreme leader does not receive a salary.

1989 Shortly before Khomeini's death, a change was made in the constitution of Iran allowing a lower ranking Shia cleric to become the supreme leader. Khomeini had a falling out with his would-be successor Hussein-Ali Montazeri, who disapproved of human rights abuses by the Islamic RepublicKeddie, Nikki R.; Yann Richard (2003). Modern Iran: Roots and Results of Revolution. New Haven, Connecticut: Yale University Press. p. 260 . such as the mass execution of political prisoners in late summer and early autumn 1988. Montazeri was demoted as a marja and Khomeini chose a new successor, a relatively low-ranking member of the clergy, Ali Khamenei. However Article 109 stipulated that the leader be "a source of imitation" (Marja-e taqlid).Schirazi, Asghar, The Constitution of Iran: politics and the state in the Islamic Republic / by Asghar Schirazi, London; New York: I.B. Tauris, 1997 p.73-75

Khomeini wrote a letter to the president of the Assembly for Revising the Constitution, which was in session at the time, making the necessary arrangements to designate Khamene'i as his successor, and Article 109 was revised accordingly. In this letter, he supposedly "emphasised that he had always been of the opinion that the marja'iyat was not a requirement for the office of leader".
