Führerhauptquartier Werwolf was the codename used for one of Adolf Hitler's World War II Eastern Front military headquarters located in a pine forest about 12 kilometres (7+1⁄2 miles) north of Vinnytsia, in Ukraine, which was used between 1942 and 1943.

The Nazis also used the term Werwolf as a codename for clandestine resistance groups which were intended to carry out guerrilla attacks against the occupying forces towards the end of World War II.

The complex was located in a pine forest about 12 kilometres (7+1⁄2 miles) north of Vinnytsia in occupied Ukraine, between the villages of Stryzhavka and Kolo-Mikhailovka on the Kyiv highway.

According to official figures, during the Nazi occupation of the region over 200,000 local civilians were killed, including 25,000 in Vinnytsia in September 1941 and April 1942.

[7] Hitler's accommodation at Werwolf (the Führerhaus) consisted of a modest log cabin built around a private courtyard with its own concrete bunker.

[8] The rest of the complex consisted of about 20 wooden cottages and barracks and up to three "B" class bunkers, surrounded by a ring of barbed wire and ground defensive positions connected by tunnels.

[10] The facility also contained a large vegetable garden organised by the German horticultural company Zeidenspiner to provide Hitler with a secure supply of food.
