Siegfried, WWV 86C, is the third of the four music dramas that constitute Der Ring des Nibelungen, by Richard Wagner. It premiered at the Bayreuth Festspielhaus on 16 August 1876, as part of the first complete performance of The Ring cycle.

Siegfried tells the coming-of-age story of the hero that Wagner has promised us at the end of Die Walküre. The most light-hearted of the four dramas, it contains genuine moments of humour. Siegfried, the son of Siegmund and Sieglinde, has been raised by the whining dwarf, Mime. However, impatient and inquisitive, he sets off on an adventure like no other. His journey through the opera traces his journey into adulthood, culminating in the meeting with our heroine, Brünnhilde, and the realisation that he must cast off his reckless youth and become a man…
