The Théâtre Dejazet is a theatre on the boulevard du Temple (popularly known as the 'boulevard du crime’) in the 3rd arrondissement of Paris. It was originally founded in 1770 by Comte d'Artois who later was crowned Charles X, but it was then closed down and not reopened until 1851. At that time it became a café-concert called the Folies-Mayer, on the site of a former jeu de paume (tennis court).
