The 21st Division (21. Division) was a unit of the Prussian/German Army. It was formed on October 11, 1866 and was headquartered in Frankfurt am Main. The division was subordinated in peacetime initially to the XI Army Corps (XI. Armeekorps) and from 1899 to the XVIII Army Corps (XVIII. Armeekorps).

The division was recruited in the formerly independent Duchy of Nassau and the Electorate of Hesse, which had been incorporated into Prussia after the Austro-Prussian War, and in the city of Frankfurt am Main.

The division was disbanded in 1919 during the demobilization of the German Army after World War I.

During the Franco-Prussian War, the 21st Infantry Division fought in the opening Battle of Woerth and the major Battle of Sedan. It subsequently participated in the Siege of Paris.

In World War I in 1914, the 21st Infantry Division fought in the Allied Great Retreat, including the First Battle of the Marne, and in the Race to the Sea. In 1916, it saw action in the Battle of Verdun and the Battle of the Somme. In 1917, it fought in the Second Battle of the Aisne. It served in the German 1918 Spring Offensive, including the Second Battle of the Somme. Allied intelligence rated the division as first class.
