Communist Party of Nicaragua

The Communist Party of Nicaragua (Partido Comunista de Nicaragua, abbr. PCdeN or PCN) is a communist party in Nicaragua. Founded as the Socialist Workers' Party (Partido Obrero Socialista) in 1967, the core founding members were Juan Lorio, Augusto Lorío, Elí Altamirano (who later served as the party's secretary general) and Manuel Pérez Estrada, who all had been expelled from the Nicaraguan Socialist Party on 23 April 1967.

The party adopted its current name on 13 December 1970.

The PCdeN was a member of the U.S.-funded National Opposition Union (UNO), a coalition of mostly right-leaning political parties which defeated the Sandinista government in the 1990 general election.
