Taihu County (Chinese: 太湖县; pinyin: Tàihú Xiàn) is a county in the southwest of Anhui Province, People's Republic of China, bordering Hubei Province to the west. It is under the jurisdiction of the prefecture-level city of Anqing and contains its westernmost point. It has a population of 560,000[when?] and an area of 2,031 km2 (784 sq mi). The seat of government is located in Jingxi Town.
Taihu is noted for its "Huating Lake" with its mountains and scenic waters. The lake was originally built for flood control and power generation with a dam constructed in the 1960s. Although it was formerly blamed for destroying large areas of farm land, it has evolved into a popular tourism location.
The county has a long history of Zen, an important tributary of Chinese Buddhism.
Taihu County has jurisdiction over 10 towns and 5 townships.
