Qeqertaq (pronounced: [qɜˈqɜtːɑq] (according to the old spelling K'eĸertaĸ)) is a settlement in the Avannaata municipality in western Greenland, located on an island off the southern shore of the Nuussuaq Peninsula in an inlet of Sullorsuaq Strait.

[2] Archaeological finds of stone tools have been made in Qeqertaq, which suggest that the site was inhabited long before the colonial era.

The Danish udstedsbestyrer (trading post administrator) lived in a wooden house with two rooms and a kitchen.

There was also an official udstedsbestyrer's apartment, which was built in 1878 as a half-timbered building with a turf wall façade and shingle roof, which had two rooms, a kitchen and a hall.

The saltwork was built in 1911 and was made from materials from an old penthouse from the long-abandoned Alluttoq (Klokkerhuk) settlement.

Qeqertaq was part of the Ilulissat Parish and belonged to the Chief Catechists' District of Appat.

During winter, Air Greenland serves the village as part of government contract, with helicopter flights to Ilulissat.

[6] During summer and autumn, when the waters of Disko Bay are navigable, communication between settlements is by sea only, serviced by Diskoline.
