The Schwentine is a river in the North German state of Schleswig-Holstein. It is approximately 62 kilometres long and rises on the hill of Bungsberg, the highest point in the state, near the village of Kasseedorf in Ostholstein. It then runs from its source to Kiel where it flows into the Kiel Fjord, a bay of the Baltic Sea. It passes through several lakes, including the Großer Plöner See.
