Chaohu (Chinese: 巢湖; pinyin: Cháohú) is a county-level city of Anhui Province, China. Situated on the northeast and southeast shores of Lake Chao, from which the city was named, Chaohu is under the administration of the prefecture-level city of Hefei, the provincial capital, and is the latter's easternmost county-level division.

Formerly it was a prefecture-level city, which held administration over Wuwei, Lujiang, He and Hanshan counties until it dissolved on 2011 August 22. The Anhui provincial government announced in a controversial decision that the prefecture-level city Chaohu was to be split into three parts and absorbed into neighboring cities. Juchao District was renamed to Chaohu as a county-level city under Hefei's administration.

Chaohu City is divided to 6 subdistricts, 11 towns and 1 township.
