The Mille Lacs Indians, also known as the Mille Lacs and Snake River Band of Chippewa, are a Band of Indians formed from the unification of the Mille Lacs Band of Mississippi Chippewa (Ojibwe) with the Mille Lacs Band of Mdewakanton Sioux (Dakota). Today, their successor apparent Mille Lacs Band of Ojibwe consider themselves as being Ojibwe, but many on their main reservation have the ma'iingan (wolf) as their chief doodem (clan), which is an indicator of Dakota origins.

The Mdewakanton or Mdewakantonwan are one of the sub-tribes of the Isanti (Santee) Dakota (Sioux). Their historic home is Mille Lacs Lake in central Minnesota. Together with the Wahpekute, they form the so-called Upper Council of the Dakota or Santee Sioux. Today their descendants are members of federally recognized tribes in Minnesota, South Dakota and Nebraska of the United States, and First Nations in Manitoba, Canada.
