Marianna Radev, also Marijana Radev, (21 November 1913 – 17 September 1973) was a Yugoslav-Croatian contralto. Radev was considered one of the great alto singers in the period after the Second World War. Above all in Italy and in Berlin, she gained a great reputation "because of her rich, expressive and seemingly never-ending alto voice". In her last years the artist lived in her Croatian homeland, where she still occasionally gave concerts. She died on 30 September 1973 at age 59 during a rehearsal for a baroque concert.
