Mokihinui (Māori: Mōkihinui) is a lightly populated locality[1] on the West Coast of New Zealand's South Island.

Mokihinui is on the Tasman Sea coastline north of Westport and is on the southern side of the Mōkihinui River's mouth, the third largest river on the West Coast.

[4] Mokihinui's population increases during whitebait season, when visitors come to fish in the Mōkihinui River's mouth.

The line continued to operate until the end of the 1970s, when the coal mining activity that provided almost the sole freight on the line declined to such a point that revenue was lower than maintenance costs.

The railway closed north of Ngakawau on 3 May 1981 and traces of its formation can be seen in the countryside around Mokihinui.
