Dilek Peninsula-Büyük Menderes Delta National Park (Turkish: Dilek Yarımadası-Büyük Menderes Deltası Millî Parkı), established on May 19, 1966, is a national park in western Turkey. It contains within its borders the entirety of the Dilek Peninsula as well as the large delta of the Büyük Menderes River. The park is located in the Kuşadası district of Aydın Province — part of Turkey's Aegean Region. Directly west of the national park is the small coastal town of Güzelçamlı, where several shuttle buses and ferries operate to and from the district's center of Kuşadası, approximately 30 km (19 mi) from the park.
The park is among the most biologically diverse of Turkey's national parks. It is the native and migratory habitat of hundreds of species of birds, mammals, plants, and marine life, some of which are entirely endemic to the park and cannot be observed anywhere else in the world. For these reasons, it is protected by numerous wildlife and wetland conventions, and is of great national and international importance in these areas.
