Chocianów [xɔˈt͡ɕanuf] (German: Kotzenau) is a town in Polkowice County, Lower Silesian Voivodeship, in south-western Poland.

As a result of the fragmentation of Poland, by the end of the 13th century the area was part of the Polish Duchy of Świdnica, ruled by a local branch of the Piast dynasty.

The settlement developed from a castle called Chodzenow built in 1297 by Duke Bolko I the Strict of Świdnica, who had to secure his lands against the claims of Wenceslaus II of Bohemia.

During World War II, in 1942–1943, the Germans operated a forced labour camp for Jewish men in the town.

[4] After Nazi Germany's defeat in World War II the town became again part of Poland.
