Zhouzhi County (simplified Chinese: 周至县; traditional Chinese: 周至縣; pinyin: Zhōuzhì Xiàn) is a county under the administration of Xi'an, the capital of Shaanxi province, China. It is the most spacious but least densely populated county-level division of Xi'an, and also contains the city's southernmost and westernmost points. Since the establishment of Huyi District in 2016, replacing the former Hu County, Zhouzhi and Lantian are the only two counties under the administration of Xi'an. Zhouzhi borders the prefecture-level cities of Xianyang to the north, Ankang to the southeast, Hanzhong to the southwest, and Baoji to the west, as well as Xi'an's Huyi District to the east. It is famous for kiwifruit, one type of produce in which Shaanxi province excels.Many of notable historical figures have visited Zhouzhi county, such as Chinese philosopher Laozi (老子), poet Bai Juyi (白居易), and British biochemist Joseph Needham.
There are some claims Yu the Great (大禹) was born in Hongqi village, Zhouzhi County.
