Russell Island is an uninhabited island of the Canadian Arctic Archipelago in the Qikiqtaaluk Region of Nunavut, Canada. It is located in the Parry Channel, separated from the northern tip of Prince of Wales Island by the narrow Baring Channel. The island is longer than it is wide. The western third of the island is separated from the other two thirds by a narrow lake and its outlet. At the northern end of the lake there is an isthmus just 1.1 km (0.68 mi) wide and this joins the two parts of the island.
