The Dadu River is named after a former port near its mouth, now the Dadu District of Taichung.

It is also known as the Black River,[2] a calque of its Hokkien name. The same name appears in English as the Wu River, the pinyin romanization of its Mandarin pronunciation. It received the name from the many black-winged birds that used to live along the river.[3]


It flows through Taichung City, Changhua County, and Nantou County for 119 kilometers (74 mi).[4][5][6] It is the 6th-longest river on Taiwan Island and the 4th-largest in terms of drainage area.[4]
