The Dudidontu River is a tributary of the Nahlin River in northwest part of the province of British Columbia, Canada.[1] It joins the Nahlin River, which forms the Inklin River, one of the main tributaries of the Taku River.[6] The Dudidontu River's watershed covers 964 km2 (372 sq mi),[5] and its mean annual discharge is 15.4 m3/s (540 cu ft/s).[5] Almost half of the Dudidontu's flow comes from its main tributary, Kakuchuya Creek, and Kakuchuya Creek's main tributary, Matsatu Creek.[5] The mouth of the Dudidontu River is located about 150 km (93 mi) northeast of Juneau, Alaska and about 110 km (68 mi) northwest of Telegraph Creek, British Columbia.

The Dudidontu River is in the traditional territory of the Taku River Tlingit First Nation, part of the Tlingit people.[7]
