Workers' Communist Party (Spain)

The Workers' Communist Party (Spain) (Spanish: Partido Comunista de los Trabajadores de España, abbreviated as PCTE) is a communist political party in Spain. It was founded in 1973 as the Partido Comunista de España (VIII-IX Congresos) (Communist Party of Spain (VIII-IX Congresses)), a split from the Communist Party of Spain (PCE). The group that formed the PCTE opposed the Eurocommunist line that was increasingly dominant within the PCE under Santiago Carrillo.

The PCTE advocates for Marxism-Leninism and the establishment of a socialist state in Spain through revolution. It opposes Spain's membership in the European Union and NATO.

The party's influence has historically been limited, and it has never achieved significant electoral success at the national level. It has, however, maintained a presence in certain regions and sectors, particularly among some segments of the working class.

The PCTE publishes a theoretical journal called Teoría Socialista (Socialist Theory). It also has a youth wing, the Juventud Comunista de los Trabajadores (Communist Youth of the Workers).
