Alfonso Jacquin Gutiérrez (30 April 1953, in Santa Marta – 7 November 1985, in Bogotá) was a Colombian lawyer and guerrilla fighter,[1] a founding member of the National Directorate of the M-19 guerrilla movement.
He was a brilliant orator and a close friend of Jaime Bateman and Carlos Toledo Plata.
After a truce had been agreed in April 1984, he took part, along with Antonio Navarro Wolff, in an attack on the La Sabana tourist train between Bogotá and Zipaquirá.
After the truce and the peace process had failed, Jacquin, together with Andrés Almarales and Luis Otero Cifuentes, was among the commanders of the "Iván Marino Ospina" company of about 40 guerrillas which stormed the Palace of Justice on 6-7 November 1985.
Jacquin was killed during the recapture of the Palace by the Colombian army and police.
