Olimpie (also spelled Olympie) is an opera in three acts by Gaspare Spontini. The French libretto, by Armand-Michel Dieulafoy (1762-1823) and Charles Brifaut (1781-1857), is based on the play of the same name by Voltaire (1761). Olimpie was first performed on 22 December 1819 by the Paris Opéra at the Salle Montansier. When sung in Italian or German, it is usually given the title Olimpia.
