Canal de la Baignerie, Historical canal in Vieux-Lille, France.

The Canal de la Baignerie is a former canal of Lille, filled in 1912. A short stretch of its bed survives between Rue des Bouchers and Rue de la Baignerie, where the protected vestiges, inscribed as monuments historiques in 1993, border an island of 18th-century houses facing Rue de la Baignerie, Place Maurice Schumann and Rue des Bouchers.

The waterway originated in the medieval period as part of the city's defensive infrastructure, then was further developed in the early 15th century after parish expansion. After centuries of use, it was filled in during the early 20th century and later officially protected as a historical monument.

The canal's name comes from the baigneries, public bathing establishments that stood along its banks. It ran beside the 1280 town ditch and was canalised around 1415 after Lille annexed the parish of Sainte-Catherine. The protected stretch lies between Rue de la Baignerie and Rue des Bouchers, near Place Maurice Schumann, formerly Place de l'Arbalète and later Place de l'Arsenal.

The remains lie in a short stretch between Rue de la Baignerie and Rue des Bouchers, near Place Maurice Schumann, served by Rihour metro station. The surrounding streets are ordinary traffic streets, not pedestrian zones, so watch for vehicles while looking at the vestiges.

The canal was filled in 1912, yet its former position remains clearly visible in the street layout and building alignment of today. Most visitors unknowingly walk directly over where the water once flowed when they explore the neighborhood.
