Zasław concentration camp (in German: Zwangsarbeitslager Zaslaw) was a World War II Nazi German concentration camp, established for ghettoised Jews in occupied Poland near the village of Zasław (now part of Zagórz in Poland), 6.7 kilometres (4.2 mi) south-east of the industrial city of Sanok which belonged to the Lwów Voivodeship of the Second Polish Republic before the invasion.

[1] Zaslaw was a forced labor camp where Polish Jews living in the city of Sanok and its vicinity were deported for confinement and exploitation before the onset of the Holocaust in occupied Poland.

Similarly as in other parts of Poland, also in Sanok the Jews were persecuted, had their property confiscated, were forced to work and systematically murdered.

Many Sanok Jews died of emaciation while working for [Nazi German] Kirchhof company [locally], which was wound up in 1942, with the employees transferred to Zasław camp.

The annihilation of Sanok Jews took place gradually rather than through a single act.On January 15, 1943, the prisoners of Zaslaw were transported to the Belzec extermination camp, where they were killed in gas chambers.
