The Bowen River is a river in northern Fiordland, New Zealand. The river runs south for 8 kilometres (5 mi) before flowing from a hanging valley to become the 162-metre (531 ft) Lady Bowen Falls and draining into the head of Milford Sound. The falls are named for Diamantina Bowen, wife of George Bowen, the fifth Governor of New Zealand.

The falls provide electricity for the Milford Sound settlement by feeding a small hydroelectric scheme, and are also the water source for the settlement.
