Hartvikvatnet

or is a lake in Narvik Municipality in Nordland county, Norway. The 2.3 km2 lake is located about 4 km east of the village of Bjerkvik and just less than 20 km with the border with Sweden. The Elvegårdsmoen military camp lies just west of the lake.

In April 1940, 11 German Junkers Ju 52 planes landed on the frozen lake with supplies for the German forces during the Battle of Narvik. 10 of the planes were not able to take off and were left on the ice. In the 1980s, some of the wrecks were salvaged, and are noe on display in museums in Norway and Germany. Tree plane wrecks are still in Hartvigvatnet.
