American Indian tribe

In the United States, an Indian tribe, Native American tribe, tribal nation or similar concept is any extant or historical clan, tribe, band, nation, or other group or community of Indigenous peoples in the United States. Modern forms of these entities are often associated with land or territory of an Indian reservation. "Federally recognized Indian tribe" is a legal term of art in United States law with a specific meaning.

An Indian tribe recognized by the United States government usually possesses tribal sovereignty, a "dependent sovereign nation" status with the Federal Government that is similar to that of a state in some situations, and that of a nation in others. Depending on the historic circumstances of recognition, the degree of self-government and sovereignty varies somewhat from one tribal nation to another.

The term is defined in the United States for some federal government purposes to include only tribes that are federally recognized by the Bureau of Indian Affairs (BIA), established pursuant to the Alaska Native Claims Settlement Act [43 U.S.C. 1601 et seq.]. Such tribes, including Alaska Native village or regional or village corporations recognized as such, are known as "federally recognized tribes" and are eligible for special programs and services provided by the United States. The BIA, part of the US Department of the Interior, issues Certificate of Degree of Indian Blood, which tribes use as a basis for tribal enrollment.

Some tribes, such as the Little Shell Chippewa, do not have federal recognition, but are recognized at the state level using procedures defined by various states, without regard to federal recognition. Other tribes are unrecognized because they no longer exist as an organized group or because they have not completed the certification process established by the government entities in question.
