Kulusuk (old spelling: Qulusuk), formerly Kap Dan, is a settlement in the Sermersooq municipality in southeastern Greenland, located on an island of the same name. The settlement population of 267 is quite uncommon for an Inuit settlement in Greenland with many Danes choosing to live there due to the airport. In Kalaallisut, the name of the village means "Chest of a Black Guillemot".
