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 release 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 Irene Papas as Clytemnestra. The score was composed by Mikis Theodorakis.

Iphigenia was nominated for one Oscar, Best Foreign Language Film. It was also nominated for the Palme d'Or at the 1977 Cannes Film Festival. Iphigenia received the 1978 Belgian Femina Award and received the Best Film Award at the 1977 Thessaloniki Film Festival, where Tatiania Papamoschou also received the Best Leading Actress Award for her role as Iphigenia.
