The Tollense (German pronunciation: [tɔˈlɛnzə], from Slavic dolenica "lowland, (flat) valley"[1]) is a river in Mecklenburg-Vorpommern in northeastern Germany, right tributary of the Peene.

The section from Lake Tollense to the junction with the Peene river near Demmin has a length of 68 km.

Afterwards, it is reached by two major tributaries, Linde river from the east and Malliner Wasser from the west.

Human remains from the Bronze Age have been found in the Tollense valley (Tollensetal) since 1997 AD and excavated since 2007.

Since the population density then was about 5 people per square kilometer, this would have been the most significant battle in Bronze Age period Germany yet to be discovered.
