The Tromper Wiek is a bay on the Baltic Sea between the peninsulas of Wittow and Jasmund on the island of Rügen in northeast Germany. This bay runs in a wide arc from Cape Arkona in the north, through the villages of Juliusruh and Glowe on both ends of the Schaabe spit, to the start of the Rügen chalk cliff area of Stubnitz east of Lohme.
