Banks Island is a massive landmass in the Canadian Arctic.

It is part of the Arctic Archipelago and sits within the Inuvik Region. This region is located in the Northwest Territories of Canada. The island is also part of the Inuvialuit Settlement Region. It is a very large island. It ranks as the fifth largest island in Canada. Globally, it is the 24th largest island on Earth.

Several bodies of water surround the island. To the west lies the Beaufort Sea. The Amundsen Gulf sits to the south and separates the island from the mainland. To the east, the Prince of Wales Strait divides Banks Island from Victoria Island. To the northeast, the M'Clure Strait sits between the island and both Melville Island and Prince Patrick Island.

The topography of the island includes the Durham Heights in the south. This area is the highest point on the island. It reaches an elevation of about 300 meters.

The island has a tundra climate, which is known as the Köppen ET climate type. This means the island experiences very long, cold winters. The summers are short and remain cool. Because it is a tundra, the island is almost entirely treeless. The Arctic willow is the tallest plant found here. It usually stays no taller than a person's knee. Occasionally, it may grow to the height of a person's knee. The land is part of the tundra world biome.

Many different animal species live on Banks Island. There are at least fourteen different mammal species. These include polar bears and barren-ground caribou. The island is also home to the endangered Peary caribou. Muskoxen are very important to the island's ecology. At one time, over 68,000 muskoxen lived there. This number represented the majority of the world's muskoxen population. However, the bacterium Erysipelothrix rhusiopathiae caused a sharp decline in their numbers.

The island is a vital place for birds. Hundreds of thousands of migratory birds visit every summer. They nest in two federal migratory bird sanctuaries. These are known as Banks Island Migratory Bird Sanctuary No. 1 and No. 2. The common raven and the ptarmigan are the only birds that live there year-round. In Aulavik National Park, 43 different bird species use the area seasonally. This park protects much of the Arctic lowlands at the northern end of the island. The Thomsen River flows through this park. It is one of the northernmost rivers in North America that can be navigated by canoe.

Human history on the island goes back thousands of years. Pre-Dorset cultural sites have been found here. These sites date back to approximately 1500 BCE. In the Inuvialuktun language, Aulavik means "place where people travel." This name reflects how the land has supported people for over 3,400 years. European contact happened much later in the island's history. In 1820, Sir William Edward Parry saw the island from Melville Island. He named it "Banks Land" to honor Sir Joseph Banks.

Exploration in the 1850s brought more names and discoveries. The McClure Arctic expedition marked the island as "Baring Island" on their maps. During this time, the ship HMS Investigator became frozen in the Prince of Wales Strait.

Captain McClure sent out sledging parties to explore. They determined that Banks Island was indeed an island. McClure almost sailed all the way around the island. However, his ship was frozen again at Mercy Bay. The crew spent three months there before escaping across the ice. In 2010, archaeologists used sonar to find the ship in Mercy Bay.

Today, the island has a very small human population. The only permanent settlement is the Inuvialuit hamlet of Sachs Harbour, or Ikahuak. It is located on the southwest coast. According to the 2021 census, only 104 people live there. The residents have deep knowledge of the local environment. They understand weather, permafrost, and erosion patterns. Many people in the community work through fishing, hunting, and travel. They even hold an annual goose hunt every spring.
