The Principality of Anhalt-Dornburg was located in what is today Germany. It was created in 1667 following the death of Prince John VI and the partition of Anhalt-Zerbst with Anhalt-Mühlingen being created along with Anhalt-Dornburg for the younger sons of Prince John VI. The principality lasted until 1742 when Princes Christian August and John Louis II inherited Anhalt-Zerbst.
