The Zhangye National Geopark (simplified Chinese: 张掖国家地质公园; traditional Chinese: 張掖國家地質公園; pinyin: Zhāngyè Guójiā Dìzhìgōngyuán) is located in Sunan and Linze counties within the prefecture-level city of Zhangye, in Gansu, China. It covers an area of 322 square kilometres (124 sq mi). The site became a quasi-national geopark on 23 April 2012 (provisional name: Zhangye Danxia Geopark). It was formally designated as "Zhangye National Geopark" by the Ministry of Land and Resources on 16 June 2016, after it passed the on-site acceptance test.

Known for its colorful rock formations, it has been voted by Chinese media outlets as one of the most beautiful landforms in China. It became a UNESCO Global Geopark in 2019.
