The Duchy of Magdeburg was a province of Brandenburg-Prussia from 1680 to 1701 and a province of the German Kingdom of Prussia from 1701 to 1807. It replaced the Archbishopric of Magdeburg after its secularization by Brandenburg. The duchy's capitals were Magdeburg and Halle, while Burg was another important town. Dissolved during the Napoleonic Wars in 1807, its territory was made part of the Province of Saxony in 1815.
