Hertha Töpper (born 19 April 1924 in Graz) is an Austrian contralto opera singer. Töpper, the daughter of a music teacher, began her singing studies at the Graz Conservatorium while still at high school. In 1954, she began her career at the Graz Opera in the role of Ulrica in Un ballo in maschera. The first Bayreuth Festival after World War II invited her in 1951 for Wagner's Ring Cycle. The same year, her first performance at the Bavarian State Opera followed as Octavian in Richard Strauss' Der Rosenkavalier. One year later, she became a contracted member there and was in 1957 part of the world premiere of Hindemith's opera Die Harmonie der Welt.
