The Save Manapouri campaign was an environmental campaign waged between 1969 and 1972 in New Zealand to prevent the raising of the levels of lakes Manapouri and Te Anau as part of the construction of the Manapouri Power Project.

Lake Manapouri is located in the South Island of New Zealand. The lake is situated within the Fiordland National Park and the wider region of Te Wahipounamu South West New Zealand World Heritage Area.
