Iphigenia (Greek: Ιφιγένεια) is a 1977 Greek film directed by Michael Cacoyannis, based on the Greek myth of Iphigenia, the daughter of Agamemnon and Clytemnestra who was ordered by the goddess Artemis to be sacrificed. Cacoyannis adapted the film, the third in his "Greek tragedy" trilogy (after the released of Electra in 1962 and The Trojan Women in 1971), from his stage production of Euripides' play Iphigenia at Aulis. The film stars Tatiana Papamoschou as Iphigenia, Kostas Kazakos as Agamemnon and the legendary actress Irene Papas as Clytemnestra. The score was composed by Mikis Theodorakis.
