The Tongelreep is a small tributary of the Dommel that flows through Belgium and the Netherlands. It begins in Belgium near Neerpelt (where the stream is called the Warmbeek) and runs into the Dommel in Eindhoven by way of Valkenswaard and Aalst. The stream runs near the Achel Abbey, the Leenderbos, the Valkenhorst estates and the Genneper Parken park area.
