Hunlen Falls is a waterfall located at the mouth of Turner Lake in the Pacific Ranges of British Columbia, Canada.

With an estimated height of 260 m (850 ft), it is tied with Takakkaw Falls in Yoho National Park for having the fourth tallest single drop of any waterfall in Canada.

Planes land on Turner Lake above Hunlen Falls and the walk on a good trail takes about 30 minutes to the unfenced viewpoint on the east rim of the canyon.

The south end of Lonesome Lake was the site of the pioneer homestead of Ralph Edwards, known as "The Birches", which was occupied from 1912 into the 1970s.
