Jelcz-Laskowice ([ˈjɛlt͡ʂ laskɔˈvʲit͡sɛ]) (German: Jeltsch-Laskowitz) is a town in Oława County, Lower Silesian Voivodeship, in south-western Poland.

The oldest traces of human settlement in present-day Jelcz-Laskowice date back to the Neolithic period.

The village of Laskowice, on the other hand, was reestablished in 1293 in a slightly different location by Duke Henry V.[2] From 1871 to 1945 the area was part of Germany, and between 1943 and 1945, during World War II, the nearby hamlet of Miłoszyce was the site of the Fünfteichen subcamp of the Nazi German Gross-Rosen concentration camp, where forced labourers built 145 mm (6 in) howitzers for the Berthawerke, a branch of the German Krupp company.

Testing grounds still feature concrete installations 2 km (1.2 miles) east of the village of Nowy Dwór.

In 1949 Polish Ministry of Defense began the production of Mobile Repair Vehicles and Ambulances for military purpose.
