The Neuendorfer Wiek and Beuchel Island Nature Reserve (German: Naturschutzgebiet Neuendorfer Wiek mit Insel Beuchel) is a nature reserve on the German Baltic Sea island of Rügen in the state of Mecklenburg-Vorpommern. It is 550 hectares in area. The island of Beuchel was designated as a reserve on 25 July 1940. In 1999 and 2004 it was extended to include the bay of Neuendorfer Wiek.
Its neighbouring villages are Trent and Neuenkirchen. Its conservation aim is the preservation of a characteristic and representative section of the North Rügen Bodden Chain, which contains rare and threatened biotope types as well as habitats for a rich variety of fish and diverse breeding and roosting birds.
The reserve is assessed as being in "good" condition. Contrary to the conservation aim, there are attempts to mine gravel.
The nature reserve is protected under the EU Habitats Directive as the Nordrügensche Boddenlandschaft Special Protection Area and a Binnenbodden von Rügen Special Area of Conservation (i.e. bird reserve).
