Arabella, Op. 79, is a lyric comedy, or opera, in three acts by Richard Strauss to a German libretto by Hugo von Hofmannsthal, their sixth and last operatic collaboration.

Richard Georg Strauss was a German composer and conductor best known for his tone poems and operas. Considered a leading composer of the late Romantic and early modern eras, he has been described as a successor of Richard Wagner and Franz Liszt. Along with Gustav Mahler, he represents the late flowering of German Romanticism, in which pioneering subtleties of orchestration are combined with an advanced harmonic style.
