The Farabundo Martí National Liberation Front (in Spanish: Frente Farabundo Martí para la Liberación Nacional, FMLN) is, since 1992, a centre-left to left-wing political party in El Salvador and formerly a coalition of five guerrilla organizations. The FMLN was formed as an umbrella group on October 10, 1980, from the left-wing guerilla organizations: the Fuerzas Populares de Liberación Farabundo Martí (FPL), Ejército Revolucionario del Pueblo (ERP), the Resistencia Nacional (RN), the Partido Comunista Salvadoreño (PCS) and the Partido Revolucionario de los Trabajadores Centroamericanos (PRTC).
