Der Wallersee is a lake in the Austrian state of Salzburg northeast of the city of Salzburg in Salzburg-Umgebung District.

Around the lake there is a hiking path of about 20 km (12 mi) length; at its southern part, it converges with the famous Camino de Santiago (Austrian route). There are two campsite resorts. It is allowed to swim and bath.

The northern shore consists of bogland since 1883 and is called Wenger Moor.
