Reńska Wieś [ˈrɛɲska ˈvjɛɕ] is a village in Kędzierzyn-Koźle County, Opole Voivodeship, in south-western Poland in the region of Upper Silesia.

Since 1742, after the defeat of Austria in the First Silesian War, Reinschdorf belonged to Prussia and in 1816 it was assigned to Landkreis Cosel.

The early 19th and 20th centuries saw a revival of the town, as Reinschdorf was located on the road between Leobschütz and Cosel, which had become one of the largest inland ports in the German Empire.

In 1864 a large sugar mill was built in the town, and in 1882 Reinschdorf was connected to the rail network.

[2] As a result, Reinschdorf remained in Germany as part of the Weimar Republic.
