Capriccio, Op. 85, is the final opera by German composer Richard Strauss, subtitled "A Conversation Piece for Music".
 The opera received its premiere performance at the Nationaltheater München on 28 October 1942.
 Clemens Krauss and Strauss wrote the German libretto.
 However, the genesis of the libretto came from Stefan Zweig in the 1930s, and Joseph Gregor further developed the idea several years later.
 Strauss then took on the libretto, but finally recruited Krauss as his collaborator on the opera.
 Most of the final libretto is by Krauss.
