La Piscine (French for “the swimming pool”) is a museum of art and industry, located in the city of Roubaix in northern France. It is more formally known as La Piscine-Musée d’Art et d’Industrie André Diligent or Le musée d’Art et d’Industrie de la ville de Roubaix, but its common name derives from the fact that it is housed in a former indoor swimming pool, with a notable art deco interior.

This somehow peculiar location was chosen because it features an outstanding art deco interior, having been built in 1927. The swimming pool remained in use until 1985, and was given a second life as an arts museum in 2000. The museum holds items that date back from 1835, most of which were collected from a textile factory that once stood next door.
