Eduard Deisenhofer (27 June 1909 – MIA 31 January 1945) was a German commander in the Waffen-SS of Nazi Germany.

Deisenhofer held various low level command positions, including service with the Leibstandarte SS Adolf Hitler in 1934 and at the Dachau concentration camp in 1935.

At the outbreak of war Deisenhofer served in the SS Totenkopf Standarte, which was responsible for the police and security measures during the Invasion of Poland.

In March 1944, Deisenhofer was sent back to a combat formation, this time to command a regiment of the 10th SS Panzer Division Frundsberg, which took part in the operation to relieve the encircled 1st Panzer Army of Generaloberst Hans-Valentin Hube in what was known as the Kamenets-Podolsky pocket.

In mid July, Deisenhofer was ordered back east to take command of the SS Division Wiking, currently engaged in heavy fighting in the area near Modlin.
