Brzezinka (Polish: [bʐɛˈʑiŋka]) is a village in the administrative district of Gmina Oleśnica, within Oleśnica County, Lower Silesian Voivodeship, in south-western Poland.

It lies approximately 11 kilometres (7 mi) north-east of Oleśnica, and 34 kilometres (21 mi) north-east of the regional capital Wrocław.

The area became part of the emerging Polish state in the 10th century. Centuries later it passed to Bohemia (Czechia), Prussia and Germany. It became again part of Poland following Germany's defeat in World War II in 1945.
