Saint-François-de-Sales Church, Catholic church in 17th arrondissement, Paris, France.

Saint-François-de-Sales Church is a Catholic parish in the 17th arrondissement of Paris made of two churches joined by a long corridor: the 1873 neo-Romanesque church at 6 rue Brémontier and the 1911–1913 Romano-Byzantine church at 15 rue Ampère. The newer facade has three round-arched portals, a mosaic of the blessing Christ under the porch, and three tall windows beneath a stone cross. Inside, a barrel-vaulted nave runs to a hemicycle apse.

The older church was built in 1873 by architect Édouard Delebarre Debay on a street with no other houses; its first stone was blessed by Bishop Langénieux and it was consecrated on 30 October 1873 by Archbishop Guibert. To serve the growing Plaine-Monceaux population, a second church by Eugène Ewald was built from 1911 to 1913 at 15 rue Ampère, its first stone blessed on 14 June 1911 and consecrated on 23 October 1913 by Cardinal Amette. A long corridor links the two buildings.

The parish keeps two churches joined by a long corridor: the 1873 neo-Romanesque church on rue Brémontier and the 1911–1913 church on rue Ampère. The newer building's porch holds a mosaic of Christ Blessing by Louis-Édouard Fournier, and its Mutin organ, inaugurated in 1920, spans the nave width so the facade windows stay visible.

The church is open to visitors throughout the year and welcomes guests during its regular hours. It helps to check when services take place, as these may affect when you can walk around freely.

The two churches are laid out "head-to-tail": the 1873 church opens at 6 rue Brémontier, the 1911–1913 church at 15 rue Ampère, and a long corridor links them directly. The newer church's organ, a Mutin inaugurated on 25 November 1920, has 35 stops on three manuals and a pedalboard, and its case spans the nave so the facade windows stay visible.
