Kasımpaşa Spor Kulübü. (Turkish pronunciation:[ˈkasɯmpaʃa], Kasımpaşa Sports Club), commercially registered as Kasımpaşa Sportif Faaliyetleri A.Ş., colloquially known Kasımpaşa, is a Turkish professional football club located in the Beyoğlu district of Istanbul.
The club was found as "Kasımpaşa Gençik Kulubü" in 1921, following the merger of two local clubs, namely "Altuntuğ" and "Kasımpaşa Terbiye-i Bedeniye Kulübü". They played their first competitive match in 1923–1924 season. The club played in the Istanbul First League between 1939–1945 and 1946–1959. The club was promoted to the Türkiye Ligi in 1959 and remained there for 5 seasons, where their best finish was 5th in 1961–62 season.
After 43 years, on 30 May 2007, the team was promoted to the Süper Lig for the second time in their history. In a dramatic match against Altay, Kasımpaşa came from behind twice to force a penalty shootout, which they won 4–3. They competed in the Süper Lig in the 2007–08 season, but were relegated back to the TFF First League.
By the beginning of the 2010–11 season, Kasımpaşa lost some of their important players due to the decisions of coach Yılmaz Vural just before the season started. After the squad weakened, the team went on a run of poor results and were relegated at the end of the season. In the 2011–12 season, the team made a rapid return to Süper Lig after play-off matches that were played in Ankara. They first beat Konyaspor 2–0 away and 4–0 at home. Then they played the final against Adanaspor and beat them 3–2 after a dramatic match on 27 May 2012. This was their 3rd consecutive victory in play-off finals since 2007. Thus, they represented their neighbourhood in Süper Lig in the 2012–13 season. Despite challenging for a UEFA Europa League spot throughout the season, rising as a dark horse in the league, a series of dismal performances in the final few matches saw Kasımpaşa finishing sixth in the table, five points away from Bursaspor on fourth, the final Europa League qualification spot.
