The Mangatainoka railway station on the Wairarapa Line was located in the Tararua District of the Manawatū-Whanganui region in New Zealand’s North Island.

Located between the stations of Pahiatua (to the south) and Ngawapurua (to the north), it served the farming settlement of Mangatainoka and surrounding districts.

[3] A new passenger-only service was provided from 1936 with the introduction of the RM class Wairarapa-type railcars, which supplemented and later replaced the Wairarapa Mail in 1948.

Other facilities included a 40 x 30 ft goods shed, loading bank, cattle and sheep yards, stationmaster's house & public urinal, and three loops off the main line for shunting wagons.

The station was upgraded in 1920 with the platform front replaced with concrete and stockyards moved south to less swampy land, which required the culverting of a small stream in the area.

[2] Today all that remains is the 1970's station building, a short passenger platform, the former loading bank, a few railway telephone poles and a single loop serving the Ravensdown fertilizer depot.
