Victoria Island is one of the Canadian arctic islands in Nunavut and Northwest Territories, Canada. It is one of the largest islands of the world, and at 217,291 square kilometers is Canada's second largest island, double the size of Newfoundland. The western third of the island belongs to the Northwest Territories Inuvik Region and the remainder is part of Nunavut's Kitikmeot Region. Melville Sound lies to the north, and the Clintock Channel and Victoria Strait lie eastward. The Northwest Territories continue on the mainland to the South across Pease Strait . On the West are Amundsen Gulf and Banks Island.

The population of the island is 1,707; 1,309 in the Nunavut part and 398 in the Northwest Territories portion (2001). The largest settlement, Cambridge Bay, lies on the southeast coast. Holman is on the west coast.

N.B. Although Victoria Island is located in Canada, it is nowhere near the City of Victoria, British Columbia, Canada; the latter is on Vancouver Island, which in turn is not to be confused with the City of Vancouver, British Columbia, on the mainland nearby or the city of Vancouver, WA, USA, situated not far from it.
