Humboldt Falls is a 275-metre (902-foot) waterfall located in Fiordland National Park on New Zealand's South Island, in the Hollyford Valley area. It is reached via the short Humboldt Falls Track, a 1.

2-kilometre return walk that begins at the end of the unsealed Hollyford Road. The well-graded trail climbs through rainforest to a lookout overlooking the falls.

To reach the trailhead, turn off Milford Road (SH94) at Marian Corner, approximately 87 kilometres from Te Anau. From the viewpoint, Humboldt Falls appears as a high veil of water dropping through bush-clad cliffs.

Two smaller waterfalls are also visible nearby — one roughly half the height of Humboldt Falls to its right, and a wisp of a fall to its left — creating a striking combined scene. A portion of the main falls is obscured by trees from the lookout.
