Pigalle (French pronunciation: ​[piɡal]) is an area in Paris around the Place Pigalle, on the border between the 9th and the 18th arrondissements. It is named after the sculptor Jean-Baptiste Pigalle (1714–1785).

Pigalle is famous for being a tourist district, with many sex shops, theatres and adult shows on Place Pigalle and the main boulevards. The neighbourhood's raunchy reputation led to its Second World War nickname of "Pig Alley" by Allied soldiers. Le Divan du Monde and the Moulin Rouge, a world-famous cabaret, are both located in Pigalle.
