Allentsteig is a municipality in the district of Zwettl, in Lower Austria, Austria.
Upon implementation of the 1945 German Instrument of Surrender and the Allied occupation of Austria, the training ground was seized by the Soviet Army and, despite raised claims for restitution, has remained a military exclusion zone (renamed Truppenübungsplatz Allentsteig) to this day, now operated by the Austrian Armed Forces.
