Sausenburg Castle is a ruined German castle on the edge of the Black Forest, just north of the town of Kandern in Baden-Württemberg, between the villages of Sitzenkirch and Malsburg-Marzell. The castle was originally the stronghold of the lords of Sausenburg, and is built on a hill, 665 metres high, known as the Sausenberg.
