芬利河（Finlay River）位于加拿大不列颠哥伦比亚省中北部，发源于奥米尼卡山中的图塔德湖，最终注入威利斯顿湖，与帕斯尼普河一同形成皮斯河。芬利河的源头也被认为是马更些河的源头。

芬利河以探险家、皮草商约翰·芬利命名，他曾在1797年到达芬利河。

The Finlay River is a 402 km long river in north-central British Columbia flowing north and thence south from Thutade Lake in the Omineca Mountains to Williston Lake, the impounded waters of the Peace River formed by the completion of the W.A.C. Bennett Dam in 1968. Prior to this, the Finlay joined with the Parsnip River to form the Peace. The headwaters of the Finlay at Thutade Lake are considered the ultimate source of the Mackenzie River. Deserters Canyon is located just north of Williston Lake.
