The Jasmund National Park is a nature reserve in the Jasmund peninsula, in the northeast of Rügen island in Mecklenburg-Vorpommern, Germany. It is famous for the largest chalk cliffs of Germany, the so called Königsstuhl (German = "king's chair"). These cliffs are up to 161 m high above the Baltic Sea. The undisturbed beech forests behind the cliffs are also part of the national park.
Consisting of only 30 km², this is the smallest national park of Germany. The park was founded in 1990 by the last government of the GDR prior to the German reunification.
On June 25th 2011 the beech forest in Jasmund National Park was added to UNESCO World Heritage List as an extension to the Primeval Beech Forests of the Carpathians and the Ancient Beech Forests of Germany
