Koşuyolu is a neighborhood in the municipality and district of Kadıköy, Istanbul Province, Turkey.

[1] It is on the Anatolian side of the city and is bordered on the northwest and northeast by the district of Üsküdar, on the east and southeast by the Kadıköy neighborhood of Acıbadem, and on the southwest by the Kadıköy neighborhood of Rasimpaşa.

[4] In 1588, Kızlarağası İbrahim Ağa built a small mosque, a fountain, and a namazgah (open-air place for prayers) at the south end of what is now the Koşuyolu neighborhood.

The meadows of the area were used as pasture for the horses of the Ottoman palace and army and as a military training ground.

[7][8] Since the 1960s, green areas in the neighborhood have decreased while building density has increased.
