Mestersvig, also called Mesters Vig, is a military outpost located in Scoresby Land, on the southwestern shore of Davy Sound in King Christian X Land, NE Greenland.

This airport is located near the Stauning Alps mountainous area.

Later Mestersvig used to be the only permanent station in the Northeast Greenland National Park; however, all of the 1986 population of 40 has been split up into the three newer Northeast Greenland National Park research stations (Danmarkshavn, Nord and Daneborg) except a permanent population of two people, although tourists visit the station occasionally.

In September 2015, as part of the newest defence agreement to increase the enforcement of sovereignty in Greenland, Mission Mestersvig was executed.

The mission was to test the responsiveness of the military of Denmark and if the equipment could handle winter weather.
