İstanbulspor is a historic Istanbul-based football club currently competing in the TFF First League, the second tier of Turkish football. The club plays its home matches at the Necmi Kadıoğlu Stadium. Founded in 1926, İstanbulspor is one of the city's oldest clubs, with yellow and black as its traditional colors. The club enjoyed its heyday in the mid-1990s, achieving promotion to the Süper Lig and securing several mid-table finishes, which included memorable victories against Istanbul's giants. The modern era has been defined by a struggle for consistency and financial stability, leading to spells in the lower divisions. Now back in the First League, the club is working towards a sustainable future. Supported by a loyal, albeit smaller, fan base that remembers its top-flight days, İstanbulspor aims to reclaim its place among Turkey's professional elite and add a new chapter to its long history.
