Trzebień [ˈtʂɛbjɛɲ] (German: Kittlitztreben) is a village in the administrative district of Gmina Bolesławiec, within Bolesławiec County, Lower Silesian Voivodeship, in south-western Poland.

The village was mentioned in the Liber fundationis episcopatus Vratislaviensis from c. 1305, when it was part of Piast-ruled Poland.

During World War II the Germans established and operated a subcamp of the Gross-Rosen concentration camp in the village, whose prisoners were about 1,700-1,800 Jews, many of whom died.

[2][3] Prisoners were mostly brought from other camps, including from Żagań, Zielona Góra, Görlitz, Frývaldov and Miłoszyce.

[3] During the 2024 Central European floods, in Trzebień, Polish firefighters rescued two American soldiers stationed in Poland who were swept away by the Bóbr River.
