There is much confusion over the names of the Indian tribes. The following is a resource of sites from where to get a list of Indian tribe names:
1. Native Languages of the Americas
This site is located at http://www.native-languages.org/languages.htm. I has a long list of names from A to Z. There are descriptions of the tribes when one clicks on the links.
2. Indian Tribes List
This site is located at https://www.warpaths2peacepipes.com/indian-tribes/indian-tribes-list.htm. It shows the most famous tribes in Native America. This is a good list for those who need a revised list.
Wikipedia has a list of federally recognized tribes. It is located at https://en.wikipedia.org/wiki/List_of_federally_recognized_tribes. Those who need to know the current names can look here.
As one can see, there are many places that provide a list of Indian tribe names. The trick is finding one that is most relevant to one’s needs.
