Die Meistersinger von Nürnberg, WWV 96, is a music drama, or opera, in three acts, by Richard Wagner. It is the longest opera commonly performed, taking nearly four and a half hours, not counting two breaks between acts, and is traditionally not cut. With Hans von Bülow conducting, it was first performed on 21 June 1868 at the National Theater in Munich, today home of Bavarian State Opera.

Wilhelm Richard Wagner was a German composer, theatre director, polemicist, and conductor who is chiefly known for his operas. Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Carl Maria von Weber and Giacomo Meyerbeer, Wagner revolutionised opera through his concept of the Gesamtkunstwerk, by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama. He described this vision in a series of essays published between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle Der Ring des Nibelungen.
