Ikerasak Fjord is a fjord in the Qaasuitsup municipality in northwestern Greenland. The fjord is filled with ice calved off from the active Store Gletscher, which empties into the fjord at its innermost end, and which flows from the Greenland ice sheet.
It is one of the fastest moving glaciers in the World, moving at 5.7 km per year. Lille Gletscher is another glacial tongue, emptying into Qaraasaap Imaa.
Ikerasak is the only settlement in the fjord, located on a oval-shaped Ikerasak Island in its northwestern part, where the fjord widens into the inner part of Uummannaq Fjord. Seasonal settlement on the shores of Nuussuaq Peninsula has been abandoned.
