Maria Farantouri (sometimes spelt Maria Farandouri) (Greek: Μαρία Φαραντούρη), born in Athens on 28 November 1947,. is a Greek singer and also a political and cultural activist. She has collaborated with prominent Greek composers such as Mikis Theodorakis, who wrote the score for Pablo Neruda's Canto General, which Farantouri performed.

During the Greek military junta (1967–1974) Maria Farantouri recorded protest songs in Europe with Mikis Theodorakis. In 1971, she recorded "Songs and Guitar Pieces by Theodorakis" with Australian guitarist John Williams which included seven poems by Federico García Lorca. She has recorded songs in Spanish ('Hasta Siempre Comandante Che Guevara'), Italian, and English ("Joe Hill" and Brecht's "Alabama Song' from Rise and Fall of the City of Mahagonny), as well as works by Greek composers Manos Hatzidakis, Eleni Karaindrou and Mikalis Bourboulis ('San Elektra' and 'Tora Xero') in which she realized a special fusion of vocal and instrumental beauty with musical accompaniment by Vangelis. She also sang the notable 'Mauthausen Cycle'.
