Bernard Harbour (Inuit: Nulahugiuq) is a bay on the mainland of Nunavut, Canada. It is situated on Dolphin and Union Strait, southwest of Sutton Island. At one time, it was the site of a Hudson's Bay Company trading post. It is also a former Distant Early Warning Line (PIN-C) and current North Warning System site. As of August 2004, there were several abandoned structures remaining at the site. The harbour is well sheltered and can accommodate ships up to 20 ft in draught. The butterfly Colias johanseni is found in the area. The Hudson's Bay Company vessel Aklavik over-wintered at Bernard Harbour, in 1930, where she sank. She was refloated and repaired. The closest inhabited community is Kugluktuk, about 100 km south of Bernard Harbour.
