Fantail Falls is a waterfall in Mount Aspiring National Park, Westland District, New Zealand.

Its name derives from the way it spreads out into the shape of a fan at its base, rather than any similarity to the tail of the native bird known as the fantail (pīwakawaka or Rhipidura fuliginosa).

[2] A 5-minute wheelchair-accessible bush walk leads to the riverbank opposite the waterfall from a carpark on State Highway 6.

[3] In addition, a steep 5 kilometres (3.1 mi) walk to the Brewster Hut, serviced by the Department of Conservation, starts at the base of the falls.

Underneath the beech canopy the forest floor is dominated by prickly shield fern (Polystichum vestitum), horopito (Pseudowintera colorata), and broadleaf (Griselinia littoralis).
