Baillie Island (Inuit: Utkraluk) is located off the north coast of Cape Bathurst in the Northwest Territories, Canada. The island formed part of the area used by the Avvaqmiut who are a branch of the Mackenzie Inuit. A rare endemic plant known as hairy rockcress or hairy braya (Braya pilosa, genus Braya of family Brassicaceae) is known to grow in five locations on the Baillie Islands as well as the nearby Cape Bathurst. The plant is listed by the Northwest Territories Species at Risk Committee as threatened and by the Committee on the Status of Endangered Wildlife in Canada as endangered.
