Hunlen Falls is a waterfall in the Pacific Ranges of the Coast Mountains of British Columbia, Canada. It is located in Tweedsmuir South Provincial Park, west of the communities of Tatla Lake, Kleena Kleene and Nimpo Lake, and east of Bella Coola. It is the highest waterfall in Canada when measured as a continuous unbroken drop of 401 m (1,316 ft). Other waterfalls such as Della Falls on Vancouver Island are higher, but are of the cascading type. Hunlen Falls drops from the north end of Turner Lake via Hunlen Creek into the Atnarko River, a tributary of the Bella Coola River.
