The Wolf's Lair (German: Wolfsschanze; Polish: Wilczy Szaniec) served as Adolf Hitler's first Eastern Front military headquarters in World War II.

The headquarters was located in the Masurian woods, near the village of Görlitz in Ostpreußen (now Gierłoż), about 8 kilometres (5 miles) east of the small East Prussian town of Rastenburg (now Kętrzyn), in present-day Poland. The central complex and the Führer's bunker were surrounded by three security zones guarded by two Schutzstaffel (SS) units: the SS-Begleitkommando des Führers, and the Reichssicherheitsdienst. The Wehrmacht's armoured Führerbegleitbrigade was held in readiness nearby but, as a part of the Heer's elite Großdeutschland Division, was used to counter-attack Red Army break-throughs in Army Group Centre's front and rescue cut-off Heer, Luftwaffe Fallschirmjager and SS panzer troops.

The 20 July Plot, an assassination attempt against Hitler, took place at the Wolf's Lair on 20 July 1944.^[
