The 79th Reserve Division (79. Reserve-Division) was a unit of the Imperial German Army in World War I. The division was formed at the end of December 1914 and organized over the next month, arriving in the line in early February 1915. It was part of the second large wave of new divisions formed at the outset of World War I, which were numbered the 75th through 82nd Reserve Divisions. The division was initially part of XXXX Reserve Corps. The division was disbanded in 1919 during the demobilization of the German Army after World War I. Two regiments of the division were raised through Prussian Guard recruit depots throughout the kingdom, while the third was raised in Prussian Saxony.
