Arbeitslager (German pronunciation: [ˈʔaʁbaɪtsˌlaːɡɐ]) is a German language word which means labor camp. Under Nazism, the German government (and its private-sector, Axis, and collaborator partners) used forced labor extensively, starting in the 1930s but most especially during World War II. Another term was Zwangsarbeitslager ("forced labor camp").
The Nazis operated several categories of Arbeitslager for different categories of inmates. The largest number of them held civilians forcibly abducted in the occupied countries (see Łapanka for Polish context) to provide labour in the German war industry, repair bombed railroads and bridges, or work on farms and in stone quarries.
