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.
