Żarnowiec is a village in Zawiercie County, Silesian Voivodeship, in southern Poland. It is the seat of the gmina called Gmina Żarnowiec. It lies in historic Lesser Poland, approximately 32 kilometres (20 mi) east of Zawiercie and 67 km (42 mi) north-east of the regional capital Katowice. Even though the village now belongs to Silesian Voivodeship, it has never been part of Silesia. Until 1975, it was administratively tied with Lesser Poland's cities of Kraków and Kielce.
