Kusadasi is a large resort town on Turkey's Aegean coast, and the center of the seaside district of the same name within Aydin Province. Kusadasi is 95 km (59 mi) south of Izmir, and about 60 km (37 mi) from Aydin. The municipality's primary industry is tourism.

The city is situated along a gulf of the same name in the Aegean. The island of Güvercinada (in English: Pigeon Island) is connected to mainland Kusadasi by a man-made causeway, and is situated adjacent to the large hill of Kese Dagi near the center of town.
