Anhui (in Chinese: 安徽 Ānhuī) is a province of the People's Republic of China. Located in eastern China across the basins of the Yangtze River and the Huaihe River, it borders Jiangsu to the east, Zhejiang to the southeast, Jiangxi to the south, Hubei to the southwest, Henan to the northwest, and Shandong for a tiny section in the north. The capital of the province is Hefei.

The name "Anhui" derives from the names of two cities in south Anhui, Anqing and Huizhou (now Huangshan City). The abbreviation for Anhui is "Wan", because there were historically a State of Wan, a Mount Wan, and a Wan river in the province.
