Hassan Zia-Zarifi (Persian: حسن ضیاظریفی; 1939 – 1975) was an Iranian intellectual and one of the ideological founders of the communist guerrilla movement in Iran. On April 18, 1975 he was executed extrajudicially along with eight others while in prison in Tehran. The execution generated tremendous internal and foreign criticism against the increasingly oppressive government of Shah Mohammed Reza Pahlavi and helped cement its reputation as a serious violator of human rights.
