Template:Short description Template:Use New Zealand English Template:Use dmy dates Template:Infobox body of water
Lake Poteriteri is the southernmost of the large lakes in Fiordland National Park in New Zealand's South Island. Only Lakes Hakapoua and Innes lie further south on the southern of New Zealand's two main islands. It is located Template:Convert to the west of the town of Tuatapere.
Lying in a steep-sided mountain valley, Poteriteri runs roughly north–south for a distance of Template:Convert with an average width of under Template:Convert. It covers an area of Template:Convert. The outflow of Poteriteri is the Waitutu River, a short Template:Convert river which flows into the western end of Foveaux Strait.
The naming of the lake is unclear. The Māori word may mean 'to drift forwards and backwards', with another theory that the spelling of the lake should be Poutiritiri, which would translate as a 'post on which offerings are hung'. A third theory is that the spelling should be Poeteretere, in which case it would mean 'dripping wet'.<ref>Template:Cite book</ref>
Access to the lake is via helicopter, a rough deer trail from Slaughter Burn or Harry's Track, a marked route from the outlet of Lake Hauroko.
