Browne Falls cascades from Lake Browne into Doubtful Sound within Fiordland National Park on New Zealand's South Island.

Fed by the overflow of a high-altitude tarn sitting 836 metres above sea level, the falls descend through temperate rainforest in a series of steep, twisting leaps before reaching the fiord near Hall Arm.

Reported heights range from 619 to 836 metres, making it one of the two leading candidates for New Zealand's tallest waterfall.

The falls were discovered and named after pioneering aerial photographer Victor Carlyle Browne, who spotted the lake and cascade during a flight over Fiordland in the 1940s.

Despite the impressive total drop, the relatively low mean gradient of around 42 degrees gives the falls a thin, aerated appearance that can blend into the surrounding cliffs and mist.

There is no walking track to the site; visitors reach it by cruise boat, kayak, or helicopter along Doubtful Sound.
