The Woluwe (Dutch pronunciation: [ˈʋoːlyʋə]; French pronunciation: [wɔlywe]) is a stream that goes through several municipalities in the south-east and east of Brussels, Belgium, and is a right tributary of the Senne in Vilvoorde. The Kleine (little) Maalbeek is a tributary of the Woluwe in Kraainem. Many ponds formed along the stream over time, among which the Mellaerts Ponds still exist. The valley of the Woluwe crosses the municipalities of Auderghem, Watermael-Boitsfort, Woluwe-Saint-Pierre, Woluwe-Saint-Lambert, Kraainem, Zaventem, Machelen and Vilvoorde.
The towns of Woluwe-Saint-Pierre, Woluwe-Saint-Lambert and Sint-Stevens-Woluwe derive their name from it.
