Czerwionka-Leszczyny is a town in Silesia in southern Poland, on the Bierawka River (tributary of the Oder), located on Silesian Highlands, about 50 km (31 mi) north of the Silesian Beskids. It is an outer suburb of Upper Silesian Metropolis, with a population of over 3 million, and a suburb of Rybnik, both making Silesian metropolitan area with a population of 4,676,983 people.
It is situated in the Silesian Voivodeship since its formation in 1999, previously in Katowice Voivodeship, and before then, of the Autonomous Silesian Voivodeship. The town of Czerwionka-Leszczyny was created in 1962 by merging former "urban-type settlements" of Czerwionka and Leszczyny and the village of Czuchów. In 1975, the name was changed to Leszczyny due to political reasons. In 1977, Dębieńsko was annexed. On November 26, 1991 the non-communist Polish government decided to change the name back to Czerwionka-Leszczyny, which happened on January 1 the following year.
