Bergen an der Dumme is a municipality in the district of Lüchow-Dannenberg, in Lower Saxony, Germany. The Polabian name of Bergen is Tjörska (spelled Tÿörska in older German reference material), probably derived from tjöra (< Slavic *goră) ‘mountain’.
Bergen an der Dumme lies in the southwestern part of the Wendland region. It is located south of the Drawehn on the southeastern edge of the Elbufer-Drawehn Nature Park. The Wustrow Dumme, western tributary of the River Jeetzel, flows through it.
