Comer's Midden was a 1916 archaeological excavation site near Thule (modern Qaanaaq), north of Mt. Dundas in North Star Bay in northern Greenland. It is the find after which the Thule culture was named. The site was first excavated in 1916 by whaling Captain George Comer, ice master of the Crocker Land Expedition's relief team, and members of Knud Rasmussen's Second Danish Thule Expedition who were in the area charting the North Greenland coast.
The site shows signs of having been inhabited from the 14th to the 20th century although Holtved reports that the 17th and 18th centuries are poorly represented. The site contains about 26 house ruins and several middens distributed over an area of about 120 m in width and stretching over 400 m inland with the midden Comer excavated located at its south end.
The majority of the houses were more or less rounded, typically around 3m to 5m across and most likely residential. One house was rectangular 4.5m by 6m, with narrow platforms along two of the walls, was probably a "qassi" or "mens' house" and was probably used as a workshop and for social gatherings.
