Paornivik Island is an uninhabited island in Avannaata municipality in northwestern Greenland.

The horseshoe-shaped Paornivik Island is located in Tasiusaq Bay, in the north-central part of Upernavik Archipelago. It is sandwiched between Qullikorsuit Island in the north − from which it is separated by the narrow Paorniviup Tunua strait − and Mernoq Island in the southwest. To the east, inner waterways of Tasiusaq Bay separate it from an unnamed nunatak on the mainland of Greenland.
