Infanterie-Division), later the 26th Panzer Division, was a military unit operational during World War II.

The 23rd Infantry participated in the invasion of Poland in 1939 as part of the reserve component of the 4th Army.

The division was commanded by Walter Graf von Brockdorff-Ahlefeldt and consisted of the 9th, 67th, and 68th infantry regiments.

Soldiers of the division, then commanded by Eduard Crasemann, were involved in the Padule di Fucecchio massacre on 23 August 1944.

This new division served on the Eastern Front for the remainder of the war, ultimately surrendering in East Prussia.
