Église Saint-Pantaléon, 16th-century Gothic and Renaissance church in Troyes, France.

Église Saint-Pantaléon is a light-grey stone church on a corner, with a tall wooden double door under a triangular pediment and a square tower capped by a steep dark slate roof. Inside, the nave rises to a rib-vaulted ceiling; the polygonal apse holds five tall stained-glass windows above a carved wooden altarpiece and a red-draped icon stand. The building measures 37.6 m long and 18.9 m wide.

The building originated as a wooden structure in 1189 and was later rebuilt in stone, sustaining damage during a major fire in 1524. Following this event, it was reconstructed blending Gothic and Renaissance architectural styles.

Locals call it "the Poles' church": since the early 20th century it has been the preferred place of worship for Catholic Polish immigrants, and Mass is still celebrated in Polish on Sundays at 10:30, before the French Mass. The Saint-Jacques chapel, rebuilt in 1538 for Nicole le Tartier, widow of mayor Jacques Dorigny, keeps their coats of arms in the stained glass and above the altarpiece.

The church stands between the cathedral and the station, bounded by rue Turenne, rue de Vauluisant, rue du marché aux Noix and rue de la Synagogue. The nave measures 37.6 m by 18.9 m. Sunday Mass is celebrated in Polish at 10:30, before the French Mass.
