Danzhou (Chinese: 儋州) is a prefecture-level city in the northwest of the Chinese island province of Hainan. Although called a "city", Danzhou administers a large area which was called Dan County or Danxian (儋县) until 1993. The administrative seat and urban center of Danzhou is Nada Town, which is often colloquially referred to as Danzhou city. Danzhou was upgraded from a county-level city into a prefecture-level city in February 2015.
