The Inklin River (Lingít: Héen Tlein) is a tributary of the Taku River in the northwest part of the province of British Columbia, Canada. It originates at the confluence of its two main tributaries, the Nahlin River and the Sheslay River and flows generally west and northwest about 83 km to join the Nakina River. The confluence of the Inklin and Nakina Rivers, at the uninhabited locality of Inklin, marks the beginning of the Taku River. The mouth of the Inklin River is located about 100 km northeast of Juneau, Alaska and about 160 km northwest of Telegraph Creek, British Columbia. The river forms the southwestern boundary of the Taku Plateau, the northwesternmost sub-plateau of the Stikine Plateau. Along the river's southeast are the Boundary Ranges of the Coast Mountains. The Inklin River's watershed covers 10463 km2, and its mean annual discharge is 177 m3/s. The lower Inklin River flows through the Nakina–Inklin Rivers/Yáwu Yaa Conservancy. Major tributaries of the Inklin River include Yeth Creek, Sutlahine River, Kaustua Creek, Kowatua Creek, Teditua Creek, and its headwater rivers, the Nahlin and Sheslay Rivers.
