city, Śląskie województwo (province), southern Poland. It is located in the centre of the Upper Silesian Basin, an industrial and mining region.

Chorzów existed as early as 1136, fell under control of several central European powers, and in 1790 became one of the first coal-mining centres in Śląsk (Silesia). In 1864 it was granted municipal rights. In 1934 old Chorzów combined with four neighbouring villages as one community. The city is located on the Kraków-Wrocław rail line and contains the Kościuszko Iron and Steel Works (founded 1802). Chorzów was once mainly German-speaking, but the expulsion of these citizens and the immigration of Poles left the population wholly Polish-speaking soon after 1945. The city contains a historical and ethnographic museum, as well as an amusement park. Pop. (2002) 117,430.
