Caddebostan

Caddebostan is a neighborhood in the Kadıköy district, on the Asian side of Istanbul, Turkey. It has a population of 20,170 (2025). Covering an area of 1.663 km², Caddebostan is bordered by the neighborhoods of Fenerbahçe in the west, Göztepe and Erenköy in the north, and Suadiye in the east. It is a generally flat neighbourhood with a shoreline to the Marmara Sea. Present-day Caddebostan roughly corresponds to the ancient Byzantine town of Rouphinianai. A research done by Marmara Municipalities Union in 2026 put Caddebostan at 4th place for quality of life among 745 Istanbul neighbourhoods.

Originally a summer resort area with mansions, beaches, and a ferry pier, Caddebostan is now a residential neighborhood with mostly midrise buildings. It is known for Bağdat Avenue, one of Istanbul’s major shopping and dining streets. The Caddebostan Coast is a popular waterfront promenade and includes a dedicated bicycle lane, which is relatively uncommon in the city. Compared with many other parts of Istanbul, Caddebostan has a higher level of walkability and more green space. Several bus lines pass through the neighbourhood, and a metro station is under construction.
