Kuşadası is a resort town on Turkey's Aegean coast, and the center of the seaside district of the same name within Aydın Province. Kuşadası is 95 km (59 mi) south of İzmir, and 71 km (44 mi) from Aydın. The municipality's primary industry is tourism.

Kuşadası has a residential population of 64,359, which can rise to over half a million in the summer as a result of the large resort filling with tourists. This also includes the hotel and bar staff, construction workers, and drivers who are required to work in/for the restaurants and other services accommodating these visitors. In addition to tourists from overseas, there is also a significant community of foreigners residing in the area.

Kuşadası caters to tourists arriving by land, or from the port for cruise ship passengers heading to Ephesus. In a controversial deal in 2003, the previously public-owned port was leased to a private company and renovated to attract luxury cruise liners. The Grand Princess docks here, along with other cruise ships.

The area features several well-known local beaches, including Ladies Beach, the beach at the centrum, the beaches between the Batıhan Hotel and the Nazilli Site, the beach at Güzelçamlı, and the Dilek Peninsula National Park beach, referred to by locals as simply Milli Park.
