The Udarser Wiek is a bay on Germany's Baltic Sea coast, covering an area of about 8 km2, between the islands of Rügen in the north and Ummanz in the south.
At the northeast end of the bay lies the island of Öhe.
The Udarser Wiek is very shallow (generally below 1.5 metres deep).
The bay was named after the village of Udars in the municipality of Schaprode on Rügen.
