The 39th Royal Bavarian Reserve Division (39. Kgl. Bayerische Reserve-Division) was a reserve infantry division of the Imperial German Army in World War I. It was raised to division status on October 2, 1914 from an ad hoc unit, "Brigade von Rekowski", and named "Division von Rekowski" ("Rekowski's Division"). On December 8, 1914 it was renamed the 39th Reserve Division. As it was heavily made up of Bavarian units, on December 26, 1916 it was again renamed, this time as the 39th Royal Bavarian Reserve Division. It spent the war engaged in positional warfare in the Alsace-Lorraine region. It was dissolved in 1919 during the demobilization of the German Army after the Armistice.
