Kadıköy (Turkish pronunciation: [kaˈdɯkøj] ) is a municipality and district in Istanbul Province, Turkey. Its area is 25 km2, and its population is 467,919 (2023). It is a large and populous area in the Asian side of Istanbul, on the northern shore of the Sea of Marmara. It partially faces the historic city centre of Constantinople (modern Fatih) on the European side of the Bosporus. 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. One of the most expensive places in Istanbul, Kadıköy is a residential and commercial area that, with its numerous bars, cinemas and bookshops, is the liberal cultural centre of the Anatolian side of Istanbul.
