Qoornoq (old spelling: Qôrnoq) is an abandoned fishing village in the Sermersooq municipality in southwestern Greenland.
The area was known to have been inhabited by the ancient pre-Inuit, Paleo-Eskimo people of the Saqqaq culture as far back as 2200 BC. It still contains archaeological ruins of ancient Inuit and Norse buildings. The site was excavated in 1952 and the remains of an old Norse farm and ancient tools were discovered. The outside walls of the farm are double hatched and contain several Inuit houses. The village was abandoned in 1972.
Qoornoq is located on the northeastern coast of the Qoornuup Qeqertarsua Island in the Nuup Kangerlua fjord, to the northeast of Nuuk, the capital of Greenland.
