Paride ed Elena (Italian pronunciation: [ˈpaːride ed ˈɛːlena]; Paris and Helen) is an opera by Christoph Willibald Gluck. It is the third of Gluck's so-called reform operas for Vienna, following Orfeo ed Euridice and Alceste, and the least often performed of the three. Like its predecessors, the libretto was written by Ranieri de' Calzabigi. The opera tells the story of the events between the Judgment of Paris and the flight of Paris and Helen to Troy. It was premiered at the Burgtheater in Vienna on 3 November 1770.
