The 3rd Division (3. Division) was a unit of the Prussian/German Army. It was formed in Stettin (now Szczecin, Poland) in May 1816 as a Troop Brigade (Truppen-Brigade). It became the 3rd Division on September 5, 1818. From the corps' formation in 1820, the division was subordinated in peacetime to the II Army Corps (II. Armeekorps). The 3rd Division was disbanded in 1919 during the demobilization of the German Army after World War I.
