Byczyna [bɨˈt͡ʂɨna] (Latin: Bicina, Bicinium; German: Pitschen) is a town in Kluczbork County, Opole Voivodeship, Poland, with 3,490 inhabitants as of December 2021.

[2] After the Prussian annexation in 1742, Byczyna, under the Germanized name Pitschen, entered a period of Germanisation, and the local school slowly diminished.

After World War I and the rebirth of independent Poland, Germany introduced a number of restrictions, including a state of emergency, to hinder the self-organization of local Poles.

[2] Smuggling became widespread, which ended only during the concentration of German troops before the invasion of Poland and start of World War II in 1939.

[2] In 1945, the population was mostly evacuated before the advancing Eastern Front, with only a few hundred people remaining, mostly local Poles and Polish forced laborers, of which over 200 were massacred by Soviet troops,[6] after their capture of the town on 18 January 1945.
