GKS KatowiceGKS Katowice is a club that was assembled from the sporting life of an entire city. It was founded on 27 February 1964 by merging a number of Katowice organisations, among them Rapid/Orzeł, Górnik Katowice, Koszutka Katowice, the skating club and even a sailing club. The initials GKS stand for Górniczy Klub Sportowy, the Miners' Sports Club, and the nickname GieKSa comes straight from them. The club plays in yellow, green and black, the colours of a mining city. It made its top-flight debut on 8 August 1965 in a match against Górnik Zabrze, and in 1968 it was joined by Dąb Katowice.
The club's golden era came in the 1980s and 1990s. In 1985 it played its first Polish Cup final and lost on penalties to Widzew Łódź, but it won the trophy the next year, in 1986, and again in 1991 and 1993. It also won the Polish Super Cup twice, in 1991 and 1995. In the league GKS finished as runners-up four times, in 1988, 1989, 1992 and 1994, and took bronze medals in 1987, 1990, 1995 and 2003. The league title never came, which is why the club is remembered mostly for its cup victories. The first European match came as early as 1970, and in the Cup Winners' Cup of 1986–87 the club beat Fram Reykjavík before losing to Sion. The club also reached the last 16 of the Cup Winners' Cup in 1991–92.
The best-known European run came in the 1994–95 UEFA Cup. After beating Cardiff in qualifying, GKS met Aris from Greece in the first round and went through on penalties, after a 1–0 win at home and a 0–1 defeat after extra time away. In the second round it faced Girondins Bordeaux and won 1–0 at home, then drew 1–1 in France, which gave it a 2–1 aggregate victory over a side from one of Europe's major leagues. In the round of 16 the club was stopped by Bayer Leverkusen, with Ulf Kirsten and Andreas Thom in their attack, losing 1–4 at home and 0–4 away. It had also met Leverkusen in the UEFA Cup in 1990–91. The best period of the club ended in the mid-1990s.
The decline was long. After relegation from the Ekstraklasa in 2005, which came amid a corruption scandal that the club's new president helped to reveal, GKS spent almost two decades outside the top flight. In 2019 it dropped from the second tier to the third and returned to the I liga in 2021. The rebuilding was backed by the city of Katowice, and the team led by coach Rafał Górak completed it on 26 May 2024. On the last matchday it won 1–0 at Arka Gdynia and secured direct promotion to the Ekstraklasa after 19 years. The return was a success, and in 2024–25 it finished eighth. In 2025–26 it took fifth place, which earned a place in the Conference League.
