Matai Falls is a 10-metre waterfall tucked into regenerating podocarp and broadleaf forest in the Catlins, on New Zealand's South Island.

It lies along the Southern Scenic Route approximately 18 km south of Ōwaka, between the settlements of Owaka and Papatowai.

A wooden viewing platform built into the streambed offers a convenient vantage point, and a fallen tree spanning the front of the falls adds a distinctive photographic element. The access track is 1. 2 km return and takes roughly 20 minutes.

About 50 metres upstream, the stream splits and drops over the smaller Horseshoe Falls, reached by a steep five-minute climb best attempted when the river is running high.

An optional extension follows the route of the old Catlins Railway line through forested cuttings and embankments, adding up to an hour to the outing.
