McLean Falls drops 22 metres on the Tautuku River within Catlins Conservation Park in the Otago region of New Zealand's South Island.

A cascade-style waterfall, it descends over a series of steep drop-offs and terraces, with the main upper drop largely obscured by the rapids and lower falls below it.

It is widely regarded as the most spectacular waterfall in the Catlins, though nearby Purakaunui Falls draws more visitors due to easier access. The falls are reached via a 2. 1 km return track off Rewcastle Road, accessed from Chaslands Highway about 11.

6 km south of Papatowai. The path winds through regenerating native bush and climbs gently before reaching the falls. Visitors can scramble over rocks to get close to the water, though surfaces can be steep and slippery.

Note that a section of the upper track passes through a rockfall zone.
