The Lac du Flambeau Band of Lake Superior Chippewa (called Waaswaaganing in Ojibwe) are a federally recognized Ojibwa Native American tribe, with an Indian reservation lying mostly in the Town of Lac du Flambeau in south-western Vilas County, and in the Town of Sherman in south-eastern Iron County in the U.S. state of Wisconsin. The Lac du Flambeau Indian Reservation, located at 45°59′05″N 89°52′38″W / 45.98472°N 89.87722°W, has a land area of 108.065 sq mi (279.887 km²) and a 2000 census resident population of 2,995 persons. Its major settlement is the unincorporated Lac du Flambeau, which had a population of 1,646 persons.
Located at Waaswaagani-zaaga'igan (French: Lac du Flambeau; English: Torch Lake), the reservation of the Lac du Flambeau Band was established under the Treaty of 1854. The band had occupied this area since 1745, when it defeated the Sioux in the last battle between the peoples, driving them to the west. The Ojibwe had gradually migrated over centuries from the Atlantic coast.
