Mangaonoho railway station was a station on the North Island Main Trunk in New Zealand. For almost a decade, from 1893 to 1902, Mangaonoho was important as the northern terminus of the NIMT's southern section; even a refreshment room was planned. The route north was delayed by construction of major viaducts, the first being Makōhine. To build Makōhine a railway workshop was set up just north of Mangaonoho. Unlike many other NIMT construction camps, Mangaonoho gradually declined after the line was completed. By 1911 the population was down to 167. Decline continued, with removal of the stockyards in 1973 and closure in 1982. There is now only a single line through the former station site.
