Klooga concentration camp was a Nazi forced labor subcamp of the Vaivara concentration camp complex established in September 1943 in Harju County, during World War II, in German-occupied Estonia near the village of Klooga. The Vaivara camp complex was commanded by German officers Hans Aumeier, Otto Brennais and Franz von Bodmann and consisted of 20 field camps, some of which existed only for short periods.
It is estimated that 1,800–2,000 prisoners perished at Klooga from wanton killings, epidemics and working conditions. Most of them were Jews. Those who survived were transported to the Stutthof concentration camp in occupied Poland ahead of the Soviet advance.
