Jiaonan (simplified Chinese: 胶南; traditional Chinese: 膠南; pinyin: Jiāonán) was a former county and county-level city under the administration of Qingdao, Shandong, China, located in the southwestern portion of Qingdao along the Yellow Sea coast. In 1945, as Zhushan County (珠山縣) it was carved from Jiao County and Qingdao City, and in 1946, renamed as Jiaonan County, deriving its name from its southern location relative to Jiaozhou Bay. In 1990, it was upgraded to a county-level city.
