The Prerower Strom, Prerow Strom or Prerowstrom is an arm of the Baltic Sea in northeast Germany. It begins near the island of Schmidtbülten in the Bodstedter Bodden and winds its way through the countryside of the peninsula of Fischland-Darß-Zingst, where it separates Darß from the peninsula of Zingst. It ends at the harbour of the village of Prerow that gives it its name. The Prerower Strom is part of the Western Pomerania Lagoon Area National Park.
