Pierre Buyoya was a Burundian army officer and politician who served two terms as President of Burundi in 1987 to 1993 and 1996 to 2003. He was the second-longest-serving president in Burundian history.

The president of Burundi, officially the President of the Republic, is the head of state and head of government of the Republic of Burundi. The president is also commander-in-chief of the National Defence Force. The office of the presidency was established when Michel Micombero declared Burundi a republic on 28 November 1966. The first constitution to specify the powers and duties of the president was the constitution of 1974 adopted in 1976. The constitution, written by Micombero, affirmed Micombero's position as the first president of Burundi. The powers of the president currently derive from the 2005 constitution implemented as a result of the 2000 Arusha Accords after the Burundian Civil War. The current president since 18 June 2020 is Évariste Ndayishimiye.
