José Napoleón Duarte, Salvadoran engineer and politician, President of El Salvador (d. 1990)
José Napoleón Duarte Fuentes (23 November 1925 – 23 February 1990) was a Salvadoran politician who served as President of El Salvador from 1 June 1984 to 1 June 1989. He was mayor of San Salvador before running for president in 1972. He lost, but the election is widely viewed as fraudulent. Following a coup d'état in 1979, Duarte led the subsequent civil-military Junta from 1980 to 1982. He was then elected president in 1984, defeating ARENA party leader Roberto D'Aubuisson.

Supported by the Reagan Administration and the Central Intelligence Agency, his time in office occurred during the worst years of the Salvadoran Civil War which saw numerous abuses and massacres of the civilian population by the Salvadoran security forces and the death squads linked to them.
