Zagłębie Lubin is a football club from Lower Silesia whose roots go back to August 1945, when a circle of the Union of Working Youth was established in Lubin with a football section. The club was formally registered on 2 March 1946 as KS Zawisza Lubin, and over the following decades it changed its name several times — to Gwardia, Spójnia, back to Zawisza, and, from 1960, following the discovery of copper deposits and the construction of a mining combine, to Górnik Lubin. The club adopted its current name, Zagłębie Lubin, on 12 February 1966, when it was reorganised as an inter-enterprise sports club backed by the region's growing copper industry.
The team plays in distinctive copper, white and green colours, referencing the raw material around which the city grew, and supporters have called the side Miedziowi (The Copper Men) for decades. The club's first major success came in the 1989–90 season, when, as a top-flight newcomer, it finished as national runner-up, behind only Lech Poznań. A year earlier, in 1989, the Lubin stadium had set an attendance record: a friendly between the Polish and Soviet national teams (1–1) drew more than 50,000 spectators. The runners-up finish earned Zagłębie its European debut, facing Italy's Bologna in the UEFA Cup.
A historic success followed in the 1990–91 season: under coach Marian Putyra, Zagłębie secured its first Polish championship, beating Zawisza Bydgoszcz 2–1 in the 29th round. The club won its second title in 2007, defeating defending champions Legia Warsaw 2–1 away from home on the final matchday — a triumph that also sealed the Polish Super Cup. Zagłębie has additionally reached the Polish Cup final three times (2005, 2006, 2014), without winning any of them.
Since 1998, the club's main sponsor and owner has been KGHM Polska Miedź, and Zagłębie has consistently invested in its own youth development — the club's Football Academy regularly supplies the first team and Poland's youth national sides with home-grown talent. Home matches are played at the Zagłębie Stadium, built to replace the former Górniczy Stadium dating from 1972.
