Le Chat Noir (French pronunciation: ​[lə ʃa nwaʁ]; French for "The Black Cat") was a nineteenth-century entertainment establishment, in the bohemian Montmartre district of Paris. It was opened on 18 November 1881 at 84 Boulevard de Rochechouart by the impresario Rodolphe Salis, and closed in 1897 not long after Salis' death.

Le Chat Noir is thought to be the first modern cabaret: a nightclub where the patrons sat at tables and drank alcoholic beverages while being entertained by a variety show on stage. The acts were introduced by a master of ceremonies who interacted with well-known patrons at the tables. Its imitators have included cabarets from St. Petersburg (Stray Dog Café) to Barcelona (Els Quatre Gats) to London's Cave of the Golden Calf.

In its heyday it was a bustling nightclub that was part artist salon, part rowdy music hall. From 1882 to 1895 the cabaret published a weekly magazine with the same name, featuring literary writings, news from the cabaret and Montmartre, poetry, and political satire. It was the subject of an iconic Théophile Steinlen poster in 1896.
