Kaiser-Wilhelm-Koog is a municipality situated along the North Sea coast in the district of Dithmarschen, in Schleswig-Holstein, Germany.

The municipality is located in and named after the polder ({{langx|de|Koog}}), which was finished in 1874 and named in honour of German Emperor William I. The Koog is entirely reclaimed land and therefore a completely flat area and is 0 meters above sea level.
