Wustrower Dumme is a river of the German states Saxony-Anhalt and Lower Saxony. It is a roughly 32 kilometres (20 mi) long, and a left, western tributary of the Jeetzel (also: Jeetze).

The Dumme runs through the border region between Altmark in the south and Wendland in the north; in places it forms the border river between Lower Saxony and Saxony-Anhalt. During its course it passes Bergen an der Dumme, before discharging into the northward-flowing Jeetzel near Wustrow, hence the first part of the name.
