Brzezinka (Polish: [bʐɛˈʑiŋka]; German: Birkental) is a dzielnica (district) of Mysłowice, Silesian Voivodeship, southern Poland.

[4] During the political upheaval caused by Matthias Corvinus the duchy was overtaken by Casimir II, Duke of Cieszyn from the Piast dynasty, who sold it in 1517 to the Hungarian magnates of the Thurzó family, forming the Pless state country.

[5] In the War of the Austrian Succession most of Silesia was conquered by the Kingdom of Prussia, including the village, and in 1871 it became part of the German Empire.

After World War I in the Upper Silesia plebiscite 2,362 out of 2,890 voters in Brzezinka voted in favour of rejoining Poland, against 523 opting for staying in Germany.

It was then annexed and occupied by Nazi Germany at the beginning of World War II.
