Alfonso Carlos Comín Ros (1933 in Zaragoza – 23 July 1980 in Barcelona) was a Spanish industrial engineer, politician, and polygraph who carried out his work in Catalonia.
He was the son of Jesús Comín Sagüés, an Aragonese prominent carlist figure.
In 1970, he joined the Organización Comunista de España (Bandera Roja) (Communist Organization of Spain (Red Flag), (OCE-BR)), but left it to found the Bandera Roja de Catalunya (Red Flag of Catalonia) in 1974, which a little later joined the Unified Socialist Party of Catalonia (Partit Socialista Unificat de Catalunya, PSUC).
In 1980, he was elected as a representative to the Parliament of Catalonia for the Province of Barcelona on behalf of the PSUC.
A big part of the political and social problem that he dealt with had to do with Andalusian immigrants in Catalonia, especially in Barcelona, from the 1950s.
