Sanningasoq (old spelling: Sáningassoq) is a large oligotrophic twin lake in central-western Greenland, in the Qeqqata municipality. It is located approximately 9 km (5.6 mi) northeast of Kangerlussuaq. It is characteristic in that it is composed of two lakes connected via a narrow water passage through a broken isthmus. Its northwestern shore is at 67°05′15″N 50°39′50″W / 67.08750°N 50.66389°W / 67.08750; -50.66389 and its southeastern shore at 67°04′00″N 50°28′53″W / 67.06667°N 50.48139°W / 67.06667; -50.48139.

The 2x10 km twin lake is separated from the Akuliarusiarsuup Kuua valley and Kangerlussuaq in the south by a low tundra ridge − part of the Kangaamiut dike swarm. To the east lies a sibling Aajuitsup Tasia lake, separated from Sanningasoq by a low marshland isthmus of little relief. To the north-east lies the 549 m (1,801 ft) Maniitsoq hill in the wide highland of Isunngua. The wide Tarajornitsut tundra highland lies to the west of the lake.
