Majorqaq is a meltwater river and valley of the same name in the Qeqqata municipality in central-western Greenland.

The river source at 65°41′30″N 50°32′00″W / 65.69167°N 50.53333°W / 65.69167; -50.53333 is an outflow glacier draining the Greenland ice sheet, in the far inland region of the country.

The river flow is variable, with large patches of quicksands across its entire length, particularly near the delta.

[2] There are advanced plans for the Alcoa aluminium smelting plant in the Qeqqata municipality.

[7][8] A hydroelectric power plant at the river source would yield an estimated energy output of 1,000 gigawatt-hours per year.
