The Midnight Sun Mosque, also known as the Inuvik Mosque or Little Mosque on the Tundra, is a non-denominational Islamic house of worship located in Inuvik, Northwest Territories, Canada. The mosque was built in 2010 for the town's small Muslim community. It is the northernmost mosque in the Western Hemisphere and the only one in North America above the Arctic Circle.

Inuvik is the only town in the Inuvik Region, and the third largest community in Canada's Northwest Territories. Located in what is sometimes called the Beaufort Delta Region, it serves as its administrative and service centre and is home to federal, territorial, and Indigenous government offices, along with the regional hospital and airport.
