Kamionka is a village in the administrative district of Gmina Piaseczno, within Piaseczno County, Masovian Voivodeship, in east-central Poland.[1] It is part of the Warsaw metropolitan area.
The village was founded in 1912 by splitting from Gołków.[2] The name probably derives from the deposits of a mixture of gravel and sand found in the area.[2] In Old Polish fine gravel was called kamień.[2]
