The Puerto Rican Communist Party (in Spanish: Partido Comunista Puertorriqueño, PCP) was a communist party in Puerto Rico founded on 23 September 1934[2] following the sugar strikes on the island that same year.

Relevant members include General Secretary Alberto E. Sánchez, president Juan Santos Rivera, and Jose A. Lanauze Rolón.

[3] In conjunction with the mid-1930s labor movements, the formation of the PCP was also internationally influenced.

[3] Indeed, there was a substantial interconnectedness between the CPUSA, Puerto Rican Communists in New York's Lower Manhattan, and the PCP.

[3] The PCP utilized their newspaper periodical Lucha Obrera (Worker's Struggle) in order to communicate their agendas and messages to the public.
