The Pohangina River is a river of the southwestern North Island of New Zealand. A tributary of the Manawatu River, it flows generally southward from its source in the Ruahine Range, joining the Manawatu River about 15 kilometres (9 mi) northeast of Palmerston North at Ashhurst. Brown and (rarely) rainbow trout live in the river but are rare above the Centre Creek confluence. The headwaters of the river above the Cattle Creek confluence are home to small numbers of whio (blue duck; Hymenolaimus malacorhynchus).
