Mangatainoka is a small settlement in the Tararua District of New Zealand's North Island.

It is located on the banks of the Mangatainoka River, 5 km (3.1 mi) north of Pahiatua.

[8] Passenger train services were originally provided by the Napier Express until it was re-routed via the former Wellington and Manawatu Railway Company's western line through the Kāpiti Coast and Horowhenua in early 1909.

Carriage trains through Mangatainoka were reintroduced in 1964 but did not fully replace the railcars until 1977.

As roads in the area improved through the 1980s, passenger numbers declined and all services north of Masterton ceased on 29 July 1988.

Since this time, only freight trains have regularly operated through Mangatainoka; passenger services have been limited to occasional excursions, typically organised by enthusiast societies.
