The Mount Cass Wind Farm is a proposed wind farm to be located east of Waipara on Mount Cass in the Canterbury region of New Zealand. The project dates back to 2006, and the current plan by MainPower is to construct 22 wind turbines along a ridge of Mount Cass.

Resource consent was initially refused by the Hurunui District Council in 2009 but approved by the Environment Court in 2011. Preliminary work began in 2019 with the intent to be completed by late 2021, but was delayed by animal conservation concerns among other issues. As of July 2024 the project's status is unclear after a major investor pulled out.
