Kadıköy (Turkish pronunciation: [kaˈdɯkøj] ) is a municipality and district in Istanbul Province, Turkey. Its area is 25 km, and its population is 467,919 (2023).

It is bordered by the districts of Üsküdar, to the northwest, Ataşehir, to the northeast, and Maltepe, to the southeast.

Kadıköy was known in classical antiquity and during the Roman and Byzantine eras as Chalcedon (Greek: Χαλκηδών). Chalcedon was known as the 'city of the blind'. The settlement has been under control of many empires, finally being taken by the Ottomans before the fall of Constantinople. At first, Chalcedon was rural, but with time it urbanized. Kadıköy separated from the Üsküdar district in 1928.
