Is a Polish association football club based in Chorzów, Upper Silesia. It is one of the most successful football teams in Poland: 14 times national champion, and 3 times winner of the Polish Cup. Currently, the team plays in the top Polish league, the Ekstraklasa.
The club was founded on 20 April 1920 in Hajduki Wielkie (then Bismarckhütte). It was known as Ruch Hajduki Wielkie until 1938, with Ruch (a common noun for motion) being sometimes interpreted by Polish patriots as a cover reference to the Silesian Uprisings.
