The Tanzilla River is a tributary of the Stikine River in northwest part of the province of British Columbia, Canada.[1]

From its source in the Three Sisters Range the Tanzilla River flows roughly north and northwest to the vicinity of the community of Dease Lake, then turns west and southwest, flowing to the Stikine River in the Grand Canyon of the Stikine. The river's total length is roughly 140 km (87 mi).[4] The Tanzilla River's mean annual discharge is estimated at 16.0 m3/s (570 cu ft/s).[5] Its watershed covers 1,833 km2 (708 sq mi).[5] The watershed's land cover is classified as 28.8% conifer forest, 27.3% shrubland, 24.4% mixed forest, 11.7% barren, 5.2% herbaceous, and small amounts of other cover.[5]

The mouth of the Tanzilla River is located about 40 km (25 mi) northeast of the community of Telegraph Creek, British Columbia, about 53 km (33 mi) southwest of Dease Lake, British Columbia, and about 220 km (140 mi) east of Juneau, Alaska.

The Tanzilla River's watershed is within the traditional territory of the Tahltan First Nation, of the Tahltan people.[6][7]
