Sarqarput Strait is a strait in the Uummannaq Fjord system in northwestern Greenland. It separates Uummannaq Island in the northeast from Nuussuaq Peninsula in the southwest. The strait waterway is part of the southern arm of Uummannaq Fjord, narrowing into Ikerasak Fjord in the southeast, at the base of Nuussuaq Peninsula. The Sarfaagfip Kussinnersua and Kuuk rivers flowing from the peninsular glaciers empty into the strait.
