Plön (German pronunciation: [ˈpløːn] ⓘ) is a district in Schleswig-Holstein, Germany.

During the 20th century some municipalities left the district due to incorporation into the city of Kiel.

The lakeland and the adjoining parts of the neighbouring district Ostholstein constitute the region called Holstein Switzerland since the countryside is very hilly.

North of the lakeland there is the Probstei, a region on the coast of the Baltic Sea.
