The Dommel is a small river in Belgium and the Netherlands, left tributary of the Dieze. It is 120 km long, of which 85 km in the Netherlands. The Dommel takes in water from the Keersop, Tongelreep, Run, Gender and Kleine Dommel streams and merges at 's-Hertogenbosch with the Aa stream to form the river Dieze, which subsequently flows towards the Meuse. The main cities and towns along the Dommel's course are Peer, Neerpelt, Valkenswaard, Dommelen, Eindhoven, Son en Breugel, Sint-Oedenrode, Boxtel, Sint-Michielsgestel and 's-Hertogenbosch.

The Dieze is a short river in North Brabant, the Netherlands, tributary of the Meuse. It is formed by the confluence of the rivers Aa and Dommel in 's-Hertogenbosch. The part of the Dieze in the centre of 's-Hertogenbosch is called Binnendieze, a partly covered network of canals. The Dieze flows into the Meuse near Hedel.
