Les vêpres siciliennes (The Sicilian Vespers) is a grand opera in five acts by the Italian romantic composer Giuseppe Verdi set to a French libretto by Eugène Scribe and Charles Duveyrier from their work Le duc d'Albe of 1838. Les vêpres followed immediately after Verdi's three great mid-career masterpieces, Rigoletto, Il trovatore and La traviata of 1850 to 1853 and was first performed at the Paris Opéra on 13 June 1855.
