The Polenlager was a system of forced labor camps in Silesia that held Poles during the World War II Nazi German occupation of Poland. The prisoners, originally destined for deportation across the border to the new semi-colonial General Government district, were sent to the Polenlager between 1942 and 1945, once the other locations became too overcrowded to accommodate the prisoners.

Silesia is a historical region of Central Europe that lies mostly within Poland, with small parts in the Czech Republic and Germany. Its area is approximately 40,000 km2 (15,400 sq mi), and the population is estimated at 8,000,000. Silesia is split into two main subregions, Lower Silesia in the west and Upper Silesia in the east. Silesia has a diverse culture, including architecture, costumes, cuisine, traditions, and the Silesian language. The largest city of the region is Wrocław.
