The South Korean National Liberation Front Preparation Committee was a left-wing and Pro-North Korea organization in South Korea active from 1976 to 1979.

The eventual goal of the SKNLF-PC was to organize the South Korean people and wage a guerrilla war similar to that of the National Liberation Front (Viet Cong) in South Vietnam, hoping to eventually create a socialist state and reunify with North Korea.

The South Korean National Liberation Front was dissolved after many members were exposed and arrested by the South Korean military regime, including poet Kim Nam-ju.

The National Liberation Front Incident is often compared to other instances where the South Korean state exposed (or at least claimed to have exposed) clandestine communist organization, such as the Revolutionary Reunification Party Incident and the People's Revolutionary Party Incident.
