Kangerluluk, meaning 'the awful fjord',[2] is a fjord in the King Frederick VI Coast, Kujalleq municipality, southern Greenland.

To the east the fjord opens into the North Atlantic Ocean between Cape Olfert Fischer and the headland of Qajartalik, just north of Qeqertatsiaq Island.

[4] The fjord has a large active glacier at its head and is frequently blocked by ice.

On the northern shore the Syenitbugt is a bay with an islet, located about 11 km from the fjord's mouth.

There are high mountains on the sides of the fjord, a craggy group known as the Kangerluluk Range (Kangerluluk Bjerge) rises to a height of 1,291 m (4,236 ft) on the northern side about 15 km within the fjord and continues westwards culminating in a massive ultra-prominent peak at 61°9′7″N 43°44′51″W / 61.15194°N 43.74750°W / 61.15194; -43.74750 towering to a height of 2,020 m (6,630 ft) above the glaciers at the head of the fjord.
