Bache Peninsula is a geological formation in Canada, on Ellesmere Island in Nunavut.
The peninsula is considered a cape', meaning that it is a headland that dramatically affects the ocean currents.
It is primarily known for being the site of the world's northernmost permanent settlement from 1926 to 1933, a Royal Canadian Mounted Police post.
The peninsula is thought to have been inhabited approximately 4,200 years ago by hunting bands originating in northeast Asia and Alaska.
Stone tools and artistic carvings have been found, dating back to the Dorset culture.
