Niingsvatnet
or is a Norwegian lake that lies high in the mountains on the border of two municipalities: Evenes in Nordland county and Tjeldsund in Troms og Finnmark county.
The water from the lake flows through a pipe down to the hydroelectric powerstation near the village of Bogen in Evenes. The powerstation is owned by Evenes Kraftforsyning and is situated at almost lower than the lake Niingsvatnet. The water from the powerstation then flows into the Strandvatnet lake. A short river goes from Strandvatnet past the village of Bogen to the Ofotfjord.
