Nattoralik, old spelling Nagtoralik,[1] is a fjord in the King Frederick VI Coast, Kujalleq municipality, southern Greenland.

There is a Paleo-Eskimo archaeological site on the northern shore of the fjord.

It extends in a roughly east–west direction from its mouth in the North Atlantic Ocean for about 8 km until its head.

Its entrance lies 3.5 mi (5.6 km) north of Nanuseq and Cape Walløe rises 4.5 mi (7.2 km) to the northeast.

[3] In the same manner as in the fjords further north, dark-hued mountains rise steeply from the coastline on both sides with heights averaging between 600 and 800 m.[4] No glaciers reach the waters of this fjord, instead the fjord bends sharply northwards at its head ending in a valley with a succession of small lakes and a 932 m (3,058 ft) high snowy peak towering above it on its eastern side.
