The Théâtre Marigny is a theatre in Paris, situated near the junction of the Champs-Élysées and the Avenue Marigny in the 8th arrondissement. It was originally built to designs of the architect Charles Garnier for the display of a panorama, which opened in 1883. The panorama was converted to the Théâtre Marigny in 1894 by the architect Édouard Niermans and became a home to operetta and other musical theatre.
