Czaniec [ˈt͡ʂaɲɛt͡s] is a village in the administrative district of Gmina Porąbka, within Bielsko County, Silesian Voivodeship, in southern Poland.

Later it belonged to the Duchy of Oświęcim, formed in 1315 in the process of feudal fragmentation of Poland and was ruled by a local branch of Piast dynasty.

In 1457 Jan IV of Oświęcim agreed to sell the duchy to the Polish Crown, and in the accompanying document issued on 21 February the village was mentioned as Czanyecz.

[2] The territory of the Duchy of Oświęcim was eventually incorporated into Poland in 1564 and formed Silesian County of Kraków Voivodeship.

It was annexed by Nazi Germany at the beginning of World War II, and afterwards it was restored to Poland.
