Mireille is an 1864 opera in five acts by Charles Gounod to a French libretto by Michel Carré after Frédéric Mistral's poem Mirèio. The vocal score is dedicated to George V of Hanover.

Charles-François Gounod, usually known as Charles Gounod, was a French composer. He wrote twelve operas, of which the most popular has always been Faust (1859); his Roméo et Juliette (1867) also remains in the international repertory. He composed a large amount of church music, many songs, and popular short pieces including his "Ave Maria" and "Funeral March of a Marionette".
