Nioghalvfjerdsbrae (79°00′N 025°00′W / 79.000°N 25.000°W), sometimes referred to as "79 N Glacier", is a large glacier located in northeast Greenland. It drains an area of 103,314 km2 (39,890 sq mi) of the Greenland Ice Sheet with a flux (quantity of ice moved from the land to the sea) of 14.3 km3 (3.4 cu mi) per year, as measured for 1996.
The glacier has had an 80 km long and 20 km wide floating tongue, widening toward its terminus north of Lambert-Land. There are two calving fronts where the glacier meets the ocean, separated by Hovgaard Island. In August 1997 the southern calving front retreated by 5 km with no significant upstream thinning.
