The Mokihunui Hydro was a proposed hydroelectric dam and power station planned for the conservation land in the Mokihinui River on the West Coast of New Zealand. The project, developed by Meridian Energy was expected to cost $300 million. In April 2010, resource consents to dam the Mokihinui River were granted to Meridian.

In May 2010 the Department of Conservation lodged an appeal with the Environment Court.

On 22 May 2012 Meridian Energy cancelled the project, withdrawing it from the Environment Court. The project was withdrawn due to high costs and environmental concerns and the project's risks and uncertainties.

The 85-megawatt (114,000 hp) power station was expected to generate up to 360 gigawatt-hours (1,300 TJ) a year, or 14 percent more than the annual electricity consumption of the entire West Coast region (317 gigawatt-hours (1,140 TJ)). It would also provide much needed electricity generation to the Upper South Island, as local generation is well short of local demand and most of the electricity has to be transmitted from the Waitaki Valley, over 600 kilometres (370 mi) away.

In 2007, Meridian Energy Limited consulted affected parties about its proposal to place a hydro-electric dam on the Mohikinui River. The dam would have been located 3 kilometres (1.9 mi) upstream from Seddonville, between it and the Mokihinui River Forks. Meridian Energy began investigating the proposal in 2006, following from similar studies conducted by the New Zealand Ministry of Works in the 1960s and 1970s. On 15 March 2008, the West Coast Regional Council called for public submissions on Meridian's applications for resource consents. Forest and Bird opposed the dam and accused Meridian of not making public a report from Landcare Research that advised that the hydro scheme would cause significant adverse environmental effects.

Meridian Energy stated that there would be recreational benefits with the lake formed by the proposed dam. Boat ramps would be provided for access onto the new lake. A local trust was planned that would have an access track, called the "Old Ghosts Road", pushed through to Lyell, following a historic gold miners route.
