The Nisko Plan, also Lublin Plan or Nisko-Lublin Plan (German: Nisko und Lublin Plan), was developed in September 1939 by the Nazi German Schutzstaffel (SS) as a "territorial solution to the Jewish Question". In contrast to the similar "Madagascar" and other Nazi plans, the Nisko Plan was put into effect between October 1939 and April 1940 by Germans' setting up the Lublin reservation, also Nisko reservation (German: Lublin Reservat or Nisko Reservat), a concentration camp, in the Generalgouvernement. The plan and the reservation take their names from the towns of Lublin and Nisko, which bordered the reservation and would have been part of it after an envisioned, but not realized, enlargement.

When the Nazis implemented the plan, they set up a variety of forced labour camps adjacent to the reservation, with the reservation supplying the camps with workforce. These were various camps of the Burggraben project, intended to fortify the Nazi-Soviet demarcation line, and the Lublin-Lipowa camp supplying the local SS units.

Nisko [ˈɲiskɔ] is a town in Nisko County, Subcarpathian Voivodeship, Poland on the San River, with a population of 15,534 inhabitants, as of 2 June 2009. Together with neighbouring city of Stalowa Wola, Nisko creates a small agglomeration.

From 1868 to 1912 under Count Roger de Rességuier and his family, the village grew to become one of the largest estates in then Austrian Galicia. A railroad station, a hospital, a church (three in present-day Nisko), schools, factories, Austrian Army Base (currently Polish Army Base) and a palace (now used as a hospital building) were built. Most of these buildings are still in use. The village was also the capital of administration unit, Nisko County.

In 1914, when World War I began, many buildings in Nisko were destroyed by the Russian Army, which attacked Austria-Hungary. In 1918, local Poles gained control over the government in Nisko and the village became part of the new-formed Second Polish Republic. After the war, Nisko began developing very quickly but did not become a town until 1933. In 1938, the Polish government made Nisko part of the Central Industrial Area. It was a milestone in history of the town, because several projects were started in the area, such as a foundry and a power-plant in the forests on the western boundary of Nisko. The programme of industrialization was stopped when Poland was attacked by Germany and Soviet Union in 1939 (see: Polish September Campaign).^{[citation needed]}
