Nunatak Glacier (Danish: Nunatakgletscher), also known as Nunatak Glacier, is a glacier in King Christian X Land, Northeast Greenland. Administratively it lies in the Northeast Greenland National Park zone.

The area where the glacier flows is remote and uninhabited.

This glacier was named Nunatak glacieren in 1899 by Swedish Arctic explorer and geologist A.G. Nathorst during the expedition he led to Greenland in search of survivors of S. A. Andrée's Arctic balloon expedition of 1897. The name was chosen owing to the tops of nunataks appearing to overhang it.

The Nunatak Glacier originates at the eastern end of the Adolf Hoel Glacier, south of the area of the Jakob Kjøde Bjerg nunatak. Strindberg Land lies to the east and the northeastern end of Andrée Land on its western side. It flows in a roughly northwest to southeast direction for about 20 km (12 mi) until its terminus at the head of the Geologfjord. The Eyvind Fjeld Glacier flows beyond the northwestern end of the Nunatak Glacier, to the west of Jakob Kjøde Bjerg.
