The Communist Party of Aragon (in Spanish: Partido Comunista de Aragón or PCA), was a political party in Aragon, Spain. The PCA was an orthodox splinter group of the Communist Party of Spain (PCE). They broke from the PCE in 1980. In 1984, the PCA merged into the Communist Party of the Peoples of Spain (PCPE), and was hence known as the PCA-PC.

The PCA-PC no longer exists.
