The Revolutionary Party of Central American Workers (Spanish: Partido Revolucionario de los Trabajadores Centroamericanos, PRTC) was a political party in Central America.
The PRTC was founded in 1975, by a sector that had left the ERP-RN after the 1972 elections. Clandestine pre-congress meetings for the founding of PRTC were held in Costa Rica, Honduras and El Salvador in 1975. Provisional 'Zonal Leaderships' were formed in these countries. The party also formed cells in Mexico and the United States. Contacts were established with activists in Belize, Guatemala, Nicaragua and Panama. In April 1975 the Liberation League was founded as a multisectoral mass front, which was to become a front organization for the party. In December 1975 the plenary session of the party congress was opened with delegates from around Central America. The PRTC was formally founded in San José on January 25, 1976. Fabio Castillo Figueroa became the General Secretary of the party. The party adopted a democratic centralism as its organizational principle.
Ideologically, the group that founded the PRTC was inspired by Marxism-Leninism, Che Guevara and the experiences of the Vietnamese national liberation struggle. The party was accused of Trotskyism by other revolutionary groups, an accusation that the party rejected.
During the period of 1976-1978, the party built up organizational structures throughout Central America with the exception of Nicaragua. The leadership was based in Costa Rica. In Guatemala, several of the leaders of the party would later join ORPA. In El Salvador, the Zonal Leadership was made up of Mario López (a.k.a. Comandante Venancio, Zonal Secretary), Manuel Federico Castillo, Luis Díaz, Humberto Mendoza, Nidia Díaz and Joaquín Morales Chávez.
