The Schierenbeke is a 2.4-kilometre-long (1.5 mi) left tributary of the Große Aue, or Neuer Mühlenbach as it is known in its upper reaches in the German state of North Rhine-Westphalia.

The stream lies entirely within the East Westphalian parish of Rödinghausen in the district of Herford.

The river flows in a west-to-east direction south of and parallel to the Wiehengebirge hills.

Their water quality of class I to II supports a large number of rare animal species.

The boundary of the region is close to the nature reserves of Wehmerhorster Wiesental and Auebachtal.
