The Wadden Sea National Parks, a UNESCO World Heritage Site, are located along the German coast of the North Sea. Named after the Wadden Sea, they consist of three national parks:
- Schleswig-Holstein Wadden Sea National Park, comprising the west coast of Schleswig-Holstein and the North Frisian Islands
- Hamburg Wadden Sea National Park, extending from the mouth of the Elbe to the tiny islands of Neuwerk and Scharhörn, part of Hamburg
- Lower Saxony Wadden Sea National Park, comprising the northern coast of Lower Saxony and including the East Frisian Islands
These national parks are divided from each other for administrative reasons, but they form a single ecological entity. The purpose of the national parks is the protection of the Wadden Sea ecoregion.
