Chapelle Saint-Fiacre du Faouët, Gothic chapel in Le Faouët, France.

Chapelle Saint-Fiacre du Faouët is a Gothic chapel in Brittany featuring a bell tower with dual turrets, decorated buttresses, and pointed arches throughout its structure. The building was constructed over several decades starting in 1450 and showcases religious architecture typical of the region.

A reused stone in a neighbouring house records that a member of the Boutteville family founded a pilgrim hospital here in 1436, suggesting an earlier chapel or pilgrimage. The present chapel was built in the second half of the 15th century; an inscription on the rood screen dates its completion to 1480, and the building is dated 1450–1480/90. It was listed as a monument historique in 1889.

The chapel's name comes from Saint Fiacre, a 7th-century Irish hermit who settled near Meaux. Its painted wooden rood screen, carved by Olivier Le Loergan and completed in 1480, was restored in 1951 to recover its original colour scheme. The pardon is held on the last Sunday of August, and the chapel belongs to the commune.

The chapel stands about 2.5 km south of Le Faouët town centre, near the D790 road towards Quimperlé, so it is reached by car or on foot rather than in the village itself. The building belongs to the commune. The pardon is held on the last Sunday of August, a day when the chapel is in use for its traditional procession.

The rood screen inscription names its maker, Olivier Le Loergan, and gives the year 1480: "L'AN 1480 FUT FAIT CEST HEVPVRE P[AR] OLIVI[ER] LE LOERGA[N] OVPVRIER". The chapel's west wall is 2.15 metres thick and carries a bell-cage with twin round-arched openings, topped by a light octagonal spire with crocketed edges.
