Moncef Marzouki (Arabic: المنصف المرزوقي‎, al-Munṣif al-Marzūqī, born 7 July 1945) is the interim President of Tunisia. Through his career he has been a human rights activist, physician and politician. On 12 December 2011, he was elected President of Tunisia by the Constituent Assembly.

Born in Grombalia, Tunisia, Marzouki studied medicine at the University of Strasbourg in France. Returning to Tunisia in 1979, he founded the Center for Community Medicine in Sousse and the African Network for Prevention of Child Abuse, also joining Tunisian League for Human Rights. In his youth, he had travelled to India to study Mahatma Gandhi's peaceful resistance. Later, he also travelled to South Africa to study its transition from apartheid.

When the government cracked down violently on the Islamist Ennahda Movement in 1991, Marzouki confronted Tunisian President Ben Ali calling on him to adhere to the law. In 1993, Marzouki was a founding member of the National Committee for the Defense of Prisoners of Conscience, but he resigned after it was taken over by supporters of the government. He was arrested on several occasions on charges relating to the propagation of false news and working with banned Islamist groups. He subsequently founded the National Committee for Liberties. He became President of the Arab Commission for Human Rights and as of 17 January 2011 (2011 -01-17)^[ref] continues as a member of its Executive Board.
