Westerhever (Danish: Vesterhever) is a municipality in Nordfriesland in the German state of Schleswig-Holstein.

Westerhever lies on the northwestern tip of the Eiderstedt Peninsula.

The Westerheversand Lighthouse is a major landmark on the peninsula which is surrounded by salt marshes.

The saltmarshes, lighthouse, and beaches attract about 80,000 visitors every year.

The first humans there built a ring dike to protect the land.
