The Tsou (Zou; Chau) are an indigenous people of central southern Republic of China (Taiwan). They are spread across three administrative entities of the Republic of China — Nantou County, Chiayi County and Kaohsiung City.
They are sometimes confused with the Thao people of Sun Moon Lake. In the year 2000 the Tsou numbered 6,169. This was approximately 1.6% of Taiwan’s total Indigenous population, making them the seventh-largest tribal group.
