Koperniki is a village in the administrative district of Gmina Nysa, within Nysa County, Opole Voivodeship, in southwestern Poland.It lies approximately 9 kilometres southwest of Nysa and 55 km southwest of the regional capital Opole. It was the ancestral village of Nicolaus Copernicus, whose great-grandfather had moved to then Polish capital Cracow in c. 1380.
The etymology of the name has been debated especially in the context of the biography of Copernicus, since at least the 1870s, surrounding two competing proposals, one suggesting the name root origin from the German word for copper, the other from the Polish word for dill.
