Kasımpaşa Spor Kulübü is a professional Turkish football club based in the Kasımpaşa district of Istanbul, competing in the Süper Lig. The club's home is the Recep Tayyip Erdoğan Stadium, which it shares with other Istanbul clubs. Founded in 1921, Kasımpaşa has a long history as a community club, traditionally alternating between the top two divisions. A significant modern era began in the 2010s under the presidency of Turgay Ciner, where the club established itself as a stable Süper Lig side known for attractive, attacking football and discovering talent. They have developed and sold numerous players to bigger clubs and across Europe. While not competing for the title, Kasımpaşa has carved a niche as a respected and often dangerous mid-table team, capable of upsetting the league's giants. The club's culture is deeply tied to its working-class neighborhood, with a small but fiercely loyal and vocal fan base that creates an intense atmosphere in their intimate stadium setting.
