Antonio García is the nom de guerre of Eliécer Erlington Chamorro Acosta (born 10 January 1956 in Mocoa, Putumayo Department), one of the main commanders of the National Liberation Army (ELN).

The ELN is a revolutionary, Marxist, insurgent guerrilla group that has been operating in several regions of Colombia since 1966.

It is said that Jacobo Arenas (the "nom de guerre" of Luis Morantes), a founder and ideological leader of the FARC-EP, was seen as a hero by García, who once stated in an interview to a Latin American journalist that he considered Arenas to be a hero, just as he considered Simón Bolívar, José Martí and Che Guevara to be heroes.

On May 26, 2008 Ecuadorean and Colombian media reported the arrest of García in Ecuador.

The arrested guerrilla was identified as Willington Claro Arévalo, alias 'Antonio'.
