Bolshevik Communist Party (Spanish: Partido Comunista Bolchevique) was a communist group in Mexico during the 1960s. PCB was founded in August 1963 by a group that had been expelled from the Mexican Communist Party (PCM) in April 1962. The group had been in operation as a faction within the Federal District Committee of the PCM, which had opposed the new leadership of the party installed at the 1960 congress. Leading members of PCB were Guillermo Rousset Banda and Santiago González.
