Pūrākaunui Falls is one of New Zealand's most photographed waterfalls, located within the Pūrākaunui Falls Scenic Reserve in the Catlins region of the South Island, about 17 kilometres south of Ōwaka.

The falls cascade 20 metres over three distinct tiers, framed by impressive podocarp and beech forest and accompanied by the calls of native birds.

A short, easy walk from the car park leads to a wooden viewing platform, with a steeper descent continuing to a lower platform that offers a closer, striking view of the falls. The upper section of the track is suitable for wheelchair access.

The falls have appeared on a New Zealand postage stamp and in numerous calendars and publications about the Catlins.
