Walter Koch (10 September 1910 – 23 October 1943) was a commander of the Fallschirmjäger during World War II who died in mysterious circumstances after openly criticising Adolf Hitler.

Shortly afterwards the Oberstleutnant and commander of Fallschirmjäger-Regiment 5 died in Berlin from injuries allegedly resulting from a motor vehicle collision.

When Fall Gelb began in May 1940, his troops saw action during the opening phase of the Battle of France during assaults on the Belgian fortress Eben-Emael, the Maas river and Albert Canal bridges.

Although Koch was wounded in the head in the battle for Hill 107 on the first day, his airborne troops quickly achieved their targets.

[citation needed] However many in his regiment believed that this was no accident and he had been most likely killed by the SS-Reichssicherheitshauptamt because of his outspoken criticism of the Commando Order.
