Söke is a town and a large district of Aydın Province in the Aegean region of western Turkey, 54 km (34 mi) south-west of the city of Aydın, near the Aegean coast. It had 68,020 population in 2010.

The district lies between the Aegean coast and the edge of the fertile alluvial plain of the Büyük Menderes River. Lake Bafa is to the south of the district. The plain contains much rich agricultural land, one of Turkey's largest cotton growing areas and also important for wheat and flour. Other income comes from handicrafts, forestry and fishing. Söke is Turkey's only exporter of culinary snails.

The Aegean region is rich in history and natural beauty, complemented with Mediterranean climate. Söke is a large town right in the centre of the region, the market town at the heart of a wealthy agricultural district, with a dramatic backdrop of mountains. Furthermore, although eclipsed by the nearby centres of tourism on the coast, Kuşadası, Didim and Bodrum, Söke does catch passing trade from the many visitors to the area, including visitors to the nearby historical site of Priene. There are a number of amenities on the highway for tourists passing through from Izmir airport to the coast, these include restaurants, service stations, and outlet stores selling cut-price clothing. The local cuisine includes çöp şiş (a shish kebab of small pieces of lamb) and pide (a flat bread pizza).
