Pigalle (French pronunciation: ​[pi.ɡal]) 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 on Place Pigalle and the main boulevards. The neighborhood's raunchy reputation led to its World War II nickname of "Pig Alley" by Allied soldiers. The Divan du Monde and the Moulin Rouge, a world-famous cabaret, are both located in Pigalle.

The area to the south of Place Pigalle is devoted to the retail of musical instruments and equipment, especially for popular music. A section of the rue de Douai consists solely of stores selling guitars, drums, and musical accessories.

Henri Toulouse-Lautrec's studio was here. Artists such as Pablo Picasso, Vincent van Gogh, and Maurice Neumont also once lived here. The works of artist Salvador Dalí can be seen at the nearby Espace Dalí.
