Browne Falls is a waterfall above Doubtful Sound, which is located in Fiordland National Park, New Zealand. In breathtaking scenery amidst temperate rain forest, the falls cascade down to the fiord near Hall Arm. Heights of 619 metres and 836 metres have been given for the falls. Their source is a tarn called Lake Browne (836 m above sea level) which when full, overflows down the side of the mountain face (similar to Sutherland's source). The stream makes 836 m height difference over 1,130 m horizontal difference, thus the mean gradient of stream is 42 degrees.
The falls are one of the two candidates for the title of New Zealand's highest waterfall. The other is sourced from a tarn behind Elizabeth Island which is also in Fiordland.There is a diversity of plant and birdlife in the vicinity and watershed of Browne Falls. Extensive stands of nothofagus dominated trees are present along with a wide variety of understory ferns and shrubs; examples of the forest floor vegetation include Crown Fern, Blechnum discolor.
