Sandy Lake Band of Mississippi Chippewa (Ojibwe: Gaa-mitaawangaagamaag-ininiwag) are a historical Ojibwa tribe located in the upper Mississippi River basin, on and around Big Sandy Lake in what today is in Aitkin County, Minnesota. Though politically folded into the Mille Lacs Band of Ojibwe, thus no longer independently federally recognized, for decades, Sandy Lake Band members have been leading efforts to restore their independent Federal recognition.
