This is a list of Presidents (and acting Presidents) of Lebanon since the creation of the office in 1926. Though it is not specifically stated in the constitution, an unwritten understanding known as the National Pact, agreed in 1943, has resulted in the holder of the post being a Maronite Christian in every electoral cycle since that time. This agreement had to be suspended twice, when two Muslims, the former Prime Ministers had to step in as acting presidents, Selim Hoss in 1988 and Fuad Siniora in 2007.

Lebanon (ⁱ/ˈlɛbənɒn/ or /ˈlɛbənən/; Arabic: لبنان‎ Libnān or Lubnān, Lebanese Arabic: [lɪbˈneːn]), officially the Lebanese Republic (Arabic: الجمهورية اللبنانية‎ al-Jumhūrīyah al-Libnānīyah, Lebanese Arabic: [elˈʒʊmhuːɾɪjje l.ˈlɪbneːnɪjje]), is a country in the East Mediterranean. It is bordered by Syria to the north and east, and Israel to the south. Lebanon's location at the crossroads of the Mediterranean Basin and the Arabian hinterland has dictated its rich history, and shaped a cultural identity of religious and ethnic diversity.

The earliest evidence of civilization in Lebanon dates back more than 7,000 years—predating recorded history. Lebanon was the home of the Phoenicians, a maritime culture that flourished for nearly 2,500 years (3000–539 BC). Following the collapse of the Ottoman Empire after World War I, the five provinces that comprise modern Lebanon were mandated to France. The French expanded the borders of Mount Lebanon, which was mostly populated by Maronite Catholics and Druze, to include more Muslims. Lebanon gained independence in 1943, and established a unique political system, known as confessionalism, a power-sharing mechanism based on religious communities – Bechara El Khoury who became independent Lebanon's first President and Riad El-Solh, who became Lebanon's first prime minister, are considered the founders of the modern Republic of Lebanon and are national heroes for having led the country's independence. French troops withdrew from Lebanon in 1946.

Amine Pierre Gemayel (Arabic: أمين بيار الجميٌل‎) (born 22 January 1942) was President of Lebanon from 1982 to 1988 and is the leader of Kataeb Party.

Born in the Lebanese village of Bikfaya, Amine Gemayel (French pronunciation: [aˈmin ʒəmaˈjɛl]) is the son of Pierre Gemayel, founder of the Kataeb Party. Gemayel was elected to the presidency by the National Assembly on 21 September 1982, in place of his brother Bachir Gemayel who had been elected the previous month but had been assassinated before taking office.

After obtaining a law degree in 1965 from the St. Joseph University in Beirut, Amine Gemayel concentrated on building up his family's newspaper business. In a 1969 by-election, he was elected to succeed his deceased uncle, Maurice Gemayel, as a member of the National Assembly; he defeated Fuad Lahoud by a margin of 54% to 41%. In 1972, in the last election to be held for 20 years, he was reelected by a large margin.^{[citation needed]}

While his younger brother Bashir was regarded as a political radical, espousing the expulsion of Palestinian guerrillas from Lebanese soil and a radical overhaul of the political system, and hinting at a possible peace settlement with Israel, Amine Gemayel was considered more moderate. Always a consensus politician, he avoided, at least in his pre-presidential years, alienating Muslim politicians as his brother had done.^{[citation needed]} When Bashir Gemayel was assassinated, therefore, Amine was regarded as a natural choice to bring together both the supporters of his slain brother, and his Muslim opponents.

Najib Azmi Mikati (Arabic: نجيب ميقاتي‎) (born 24 November 1955) is a Lebanese politician, billionaire and is the current Prime Minister of Lebanon since 13 June 2011. From April 2005 to July 2005 he was Prime Minister of Lebanon in a caretaker government. On January 25, 2011, Mikati was nominated to serve as Prime Minister by a majority of the votes in the parliamentary consultations following the 12 January fall of the Lebanese government of November 2009. The government was formed in June, after many delays.

Mikati was born into Sunni Muslim family. He graduated from the American University of Beirut in 1980 with a Master of Business Administration (MBA) degree. He also attended a summer school program held at Harvard and the prestigious French business school INSEAD.

He co-founded the telecommunications company Investcom with his brother Taha in 1982. He sold the company in June 2006 to South Africa's MTN Group for $5.5 billion. In 2012, Forbes estimated his wealth at $3 billion, making him the richest man living in Lebanon.

The President of Iran is the highest popularly elected official in, and the head of government of the Islamic Republic of Iran; although subordinate to the Supreme Leader of Iran, who functions as the country's head of state. According to the constitution of the Islamic Republic of Iran the president is responsible for the "functions of the executive", such as signing treaties, agreements etc. with other countries and international organizations; the national planning and budget and state employment affairs; appointing ministers, governors, and ambassadors subject to the approval of the parliament.

Unlike some other countries, for example the United States, in Iran the office of president does not bestow full control over foreign policy, the armed forces, or the nuclear policy of the Iranian state, which are ultimately under the control of the Supreme Leader.

The President of Iran is elected for a four-year term by the direct vote of the people and may not serve for more than two consecutive terms.
