Northeast Greenland National Park (Greenlandic: Kalaallit Nunaanni nuna eqqissisimatitaq, Danish: Grønlands Nationalpark) is the world's largest national park and the 10th largest protected area (the only larger protected areas consist mostly of sea).

It protects 972,000 km2 (375,000 sq mi)[2] of the interior and northeastern coast of Greenland and is larger than the area of Tanzania, but smaller than that of Egypt.

Originally established on 22 May 1974 from the northern, practically uninhabited part of the former Ittoqqortoormiit Municipality in Tunu (East Greenland), in 1988, the park was expanded by another 272,000 km2 (105,000 sq mi) to its present size, adding the northeastern part of the former county of Avannaa (North Greenland).

In 2008, only 31 people and about 110 dogs were present over winter in North East Greenland, distributed among the following stations (all on the coast, except Summit Camp):[3][4] During summer, scientists add to these numbers.

An estimated 5,000 to 15,000 musk oxen, as well as numerous polar bears and walrus, can be found near the coastal regions of the park.
