The 43rd Reserve Division (43. Reserve-Division) was a unit of the Imperial German Army in World War I. The division was formed in August 1914 and organized over the next two months. It was part of the first wave of new divisions formed at the outset of World War I, which were numbered the 43rd through 54th Reserve Divisions. The division was disbanded in 1918 and its assets distributed to other divisions. The division was part of the XXII Reserve Corps and was raised through the depots of the elite Prussian Guard, and thus recruited throughout Prussia.
