Beykoz

Beykoz (Turkish pronunciation:) is a municipality and district of Istanbul Province, Turkey. Its area is 310 km, and its population is 246,833 (2025). It is located in the Anatolian Side, at the northern end of the Bosphorus. The name is believed to be a combination of the words bey and kos, whichmeans "village" in Farsi. Beykoz includes an area from the streams of Küçüksu and Göksu (just before Anadoluhisarı) to the opening of the Bosphorus into the Black Sea, and the villages in the hinterland as far as the Riva creek. Before the Turkish alphabet reform of 1928, it was sometimes Latinized variously as Beicos or Beikos.
