Manfred Jung (9 July 1940 – 14 April 2017) was a German operatic tenor, who performed Wagner's heldentenor roles internationally, including the Metropolitan Opera and the Bayreuth Festival where he was Siegfried in the Jahrhundertring, but he also sang all other tenor roles in Der Ring des Nibelungen.

He was engaged at the Kammeroper (Chamber Opera) in Cologne, from 1971 to 1975 at the Opernhaus Dortmund,[2] where he appeared in 27 lyrical tenor roles, including leading roles such as Tamino in Mozart's Die Zauberflöte and Hans in Smetana's Die verkaufte Braut.

[3] He then moved to the Pfalztheater in Kaiserslautern, where he performed more dramatic roles such as Max in Weber's Der Freischütz and Don José in Bizet's Carmen.

When he appeared as a guest in Berlin in November 1976, he was recommended to the Bayreuth Festival, and appeared there as Siegfried in Götterdämmerung from 1977, in the Jahrhundertring staged by Patrice Chéreau for the centenary of the festival and the stage work, alongside Gwyneth Jones as Brünnhilde, and conducted by Pierre Boulez.

Jung and the rest of the cast received the Grammy Award for Best Opera Recording for their recording of the Jahrhundertring conducted by Pierre Boulez, as Siegfried in both Siegfried and Götterdämmerung at the 25th Annual Grammy Awards.
