The Yakoun River (Haida: Yaaguun G̱andlee[6]) is the largest river of Haida Gwaii, in the province of British Columbia, Canada.[1] Located on Graham Island it flows about 58 km (36 mi)[4] from Yakoun Lake north to Masset Inlet, a large saltwater bay located in the heart of the Graham Island and connected to the Pacific Ocean at Dixon Entrance via a long narrow inlet called Masset Sound.

The Yakoun River's watershed covers 550 km2 (210 sq mi),[5] and its mean annual discharge is an estimated 32.6 m3/s (1,150 cu ft/s).[5] The mouth of the Yakoun River is located about 3.5 km (2.2 mi) south of Port Clements, 40 km (25 mi) south of Masset, and about 46 km (29 mi) north of Skidegate. It is about 145 km (90 mi) west of Prince Rupert on the mainland. Vancouver is about 800 km (500 mi) to the southeast.[2] The river's watershed's land cover is classified as 63.4% conifer forest, 22.5% shrubland, and small amounts of other cover.[5]
