Çeşme is a coastal town and the center-town of the district of the same name in Turkey's western-most end, on a promontory on the tip of the peninsula which also carries the same name and which extends inland to form a whole with the wider Karaburun Peninsula. It is a popular holiday resort and the district center, where two thirds of the district population is concentrated, is located 85 km. west of İzmir, the largest metropolitan center in Turkey's Aegean Region.
There is a six-lane highway connecting the two cities. Çeşme district has two neighboring districts, Karaburun to the north and Urla to the east, both of which are also part of İzmir Province. The name "Çeşme" means "fountain" and possibly draws reference from the many Ottoman fountains scattered across the city.Ilıca is a large resort area 5 km west of Çeşme to which it depends administratively, although it bears aspects of a township apart in many of its characteristics.
