Kolejowy Klub Sportowy Lech Poznań S.A., commonly referred to as KKS Lech Poznań or simply Lech Poznań (Polish pronunciation: [lɛx ˈpɔznaj̃]), is a Polish professional football club based in Poznań and currently competing in the Ekstraklasa, the nation's highest division. The club was established on 19 March 1922 as KS Lutnia Dębiec, later changing its name several times. Until 1994, the club was closely linked to Polish State Railways (PKP). As a result, its popular nickname is Kolejorz [kɔˈlɛjɔʂ], which means The Railwayman in local slang.
