Capelle aan den IJssel (Dutch pronunciation:[kaːˈpɛləʔaːndənˈɛisəl]ⓘor[-dəˈʔɛi-]; transl. "Capelle on the IJssel") is a large town and municipality in the western Netherlands, in the province of South Holland. The municipality had a population of 67,319 in 2021, and covers an area of 15.40 km2 (5.95 sq mi), of which 1.26 km2 (0.49 sq mi) is water. It is situated on the eastern edge of Rotterdam, on the Hollandse IJssel river.
The town has what is probably the country's smallest museum, the Dief- en Duifhuisje ("House of Thieves and Pigeons"). Now a historical museum, it served as the prison for the castle of Capelle and is all that now remains of the 17th-century castle.
Capelle aan den IJssel has its own train station, Capelle Schollevaar. This station is located outside of the town centre in the Schollevaar neighborhood. Local trains from Rotterdam to Gouda and Amsterdam stop at this station.
