Elektra is an opera in one act by the German composer Richard Strauss (see Strauss, Richard). It uses a libretto (text) in German, written by Hugo von Hofmannsthal based on Hofmannsthal's own drama of 1903. Both the play and libretto follow the ancient Greek tragedy written by Sophocles in the late 400's B.C. Strauss's opera received its first performance in Dresden on Jan. 25, 1909.
