José Domingo Monterrosa Barrios (4 August 1940 – 23 October 1984) was a military commander of the Armed Forces of El Salvador during the Salvadoran Civil War.

He was killed in a helicopter crash when a bomb planted by the Farabundo Martí National Liberation Front (FMLN) in a radio transmitter detonated over Joateca.

Monterrosa was known to be obsessed with destroying the pro-rebel Radio Venceremos, which "specialized in ideological propaganda, acerbic commentary, and pointed ridicule of the government".

[4] Monterrosa was a supporter of President José Napoleón Duarte's efforts to hold peace talks in 1984, and his death seriously weakened them.

[5] The Farabundo Martí National Liberation Front (FMLN) set a booby trap in fake rebel radio transmitter that Monterrosa took with him as a victory trophy.
