(; "The Master-Singers of Nuremberg"), 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. The story is set in Nuremberg in the mid-16th century.

One of the main characters, the cobbler-poet Hans Sachs, is based on a historical figure, Hans Sachs (1494–1576), the most famous of the master-singers.

It is the only mature Wagner opera based on an entirely original story, and in which no supernatural or magical powers or events feature. It incorporates many of the operatic conventions that Wagner had railed against in his essays on the theory of opera: rhymed verse, arias, choruses, a quintet, and even a ballet.

I was especially intrigued by the institution of the Marker and his function in rating master-songs ... I conceived during a walk a comic scene in which the popular artisan-poet, by hammering upon his cobbler's last, gives the Marker, who is obliged by
