Église Saint-Augustin de Lyon, Catholic church in 4th arrondissement, Lyon, France.

Église Saint-Augustin de Lyon is a Catholic church at the corner of rue Denfert-Rochereau and rue Jacquard, built in 1910–1912 by architect Augustin Chomel in slag-brick concrete. Its facade sets a neo-Romanesque portal with a mosaic tympanum and a statue of Saint Augustine inside a colossal round arch; the bell tower stands over the transept crossing. Inside, a nave flanked by side aisles runs along a colonnade of round arches under an exposed timber roof.

The church was constructed in 1912 by architect Augustin Chomel during a period of urban expansion in Lyon. It represents the religious building efforts of that era as the city grew and developed new neighborhoods.

The parish name recalls the Discalced Augustinians, who settled on the Croix-Rousse plateau in 1624 and built the nave of what is now Saint-Denis church. The tympanum mosaic by J. Schultz shows Christ visiting a canuts' workshop, linking the church to the silk workers of the neighbourhood.

The church stands at the corner of rue Denfert-Rochereau and rue Jacquard, in the 4th arrondissement on the Croix-Rousse plateau, not on the boulevard. The entrance portal opens at street level, reached by steps from the pavement. The building was renovated in 2017-2018; check Mass times before visiting, as the interior is open around services.

The church was built with slag concrete to keep costs down, so the architect compensated with the play of lines and stepped volumes, most visible at the chevet. The bell tower stands at the crossing of the transept, a Romanesque touch in an otherwise eclectic design.
