Cao Zhiyun (Chinese: 曹志耘; pinyin: Cáo Zhìyún), born in Jinhua, Zhejiang in 1961 is a Chinese linguist and dialectologist and is currently a professor at Beijing Language and Culture University. He is most well known for his work as the primary editor of the groundbreaking 2008 Linguistic Atlas of Chinese Dialects but has made numerous other significant contributions to Chinese dialectology with a focus on the Southern Wu varieties in and around his native Jinhua. Despite his focus, his works exhibit an all around thorough and in-depth understanding of all Chinese dialect families and contemporary linguistics and is widely regarded in the field as one of China's leading authorities on Chinese dialectology.
