Chapelle Saint-Yves de Rennes, Gothic chapel in central Rennes, France.

Chapelle Saint-Yves is a Flamboyant Gothic chapel at the corner of rue Saint-Yves and rue Le Bouteiller in Rennes. Its main facade on rue Le-Bouteiller has a low-arched entrance door beneath three empty niches, while the rue Saint-Yves side shows four windows, one very large, and a low door also topped by niches. Inside, a single rectangular nave has a vault and 15th-century carved timber beams.

The chapel was built in 1494 as part of a hospital dedicated to Saint-Yves, replacing an earlier 14th-century structure. In the 19th century, the building briefly served as a hardware store before eventually becoming what it is today.

The chapel now serves as a center for architecture exhibitions, where visitors learn about regional building styles and techniques. The space shows how the community preserves knowledge about local construction traditions.

The chapel is easily accessible via Metro line A at République station or line B at Saint-Germain station. Several bus routes stop nearby, making it convenient to reach from anywhere in the city center.

The chapel's nave keeps 15th-century carved timber beams, and a 1673 altarpiece by François Gillet is recorded in the 1793 inventory. Stained glass by Gérard Lardeur was installed in 1997. The building was classified as a monument historique on 10 March 1945 and bought by the city in 1981.
