The Marne River, part of the River Murray catchment, is a river that is located in the Barossa Ranges region in the Australian state of South Australia.

The Marne River rises below Eden Valley on the eastern slopes of the Mount Lofty Ranges and flows generally east before reaching its confluence with the River Murray at Wongulla. The Marne flows through Cambrai. The Marne descends 361 metres (1,184 ft) over its 70-kilometre (43 mi) course.

In pre-European times, the Ngarrindjeri people used the Marne Valley as a route up into the hills to trade with the Peramangk people in the Barossa Valley and to cut bark canoes from the River Red Gums in the hills which had thicker bark than those near the Murray. The original name of the Marne River was Taingappa, meaning footrack-trading road.

Before 1917, it was called the Rhine River South. Due to anti-German sentiment during World War I, it was renamed after the Marne River of France, where the German advance was stopped in 1914.
