Anhui (Chinese: 安徽; pinyin: Ānhuī) is a landlocked province of the Republic of China located in the northeastern region of the country. Located across the basins of the Yangtze River and the Huai River, it borders Jiangsu to the east, Zhejiang to the southeast, Jiangxi to the south. It also borders the PRC's Hupei province to the southwest, Honan to the northwest, and Shantung for a tiny section in the north. The provincial capital is Hefei.

The name "Anhui" derives from the names of two cities: Anqing and Huizhou (now Huangshan City). The abbreviation for Anhui is "Chinese: 皖; pinyin: wǎn" after the historical State of Wan, Mount Wan, and the Wan river.
