The Wustrow Dumme (German: Wustrower Dumme) is a roughly 26 km long, left, western tributary of the River Jeetzel (also: Jeetze) in Saxony-Anhalt and Lower Saxony (Germany).
The river name, Dumme, means something like Eichenbach or "oak stream", because Dumme goes back to the Old Slavic word, dabu, meaning "oak". It is thus unrelated to the German word "dumm", which means "dumb".
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.
