Zeytinburnu (literally, Olive Cape) is a working-class neighbourhood, municipality (belediye) and district on the European side of İstanbul, Turkey, on the shore of the Marmara Sea just outside the walls of the ancient city, beyond the fortress of Yedikule.

The leather industry has largely moved out to Tuzla now but the rows of six-storey blocks of housing and textiles remains. Although some improvements have been made to the streets and drainage the area still has a reputation for being the home of tough men and uncontrollable youths who drive around in cars blasting out pop music at high-volume. Possibly this is exaggerated nowadays, and steps are being taken to smarten up the area. Most residents are working class, recent migrants from Anatolia, typically lacking in education. However, the younger generations are more educated thus changing the shape of Zeytinburnu.

To integrate the district with the rest of Istanbul, the municipality has improved the transportation by extending the modern tram line to Zeytinburnu, and the main tram station is now at the intersection of the metro line leading to Atatürk International Airport and Aksaray and fast tram lines leading to Istanbul’s inter-city coach station and the old city in Eminönü. Moreover, Zeytinburnu has a station on the suburban railway line Sirkeci-Halkalı. Other important projects have improved the transportation, life quality and the economics of the district. Olivium Outlet Center was opened in 2000 , a modern shopping mall with cinemas, but with many shops specializing in factory surpluses, this has brought new shopping opportunities for the people of Zeytinburnu and surrounding districts, it’s very crowded at weekends.

There is an Alevi community served by the Erikli Baba Cemevi
