List of extinct Indigenous peoples of Brazil
At the time of the discovery of Brazil by the Europeans, a total of 2,000 Indigenous nations, divided into several thousand tribes, existed in Brazil. The total number of Native tribes which inhabited present day Brazil at the time of first contact is disputed and difficult to ascertain. The names of large number of tribes who were exterminated as a result of intertribal warfare are not recorded anywhere and so is the case of several smaller tribes who were wiped out by the colonizers. Curt Nimuendajú gives a list of 1,400 nations in his monumental work Mapa etno-histórico do Brasil e regiões adjacentes, but he ignored many smaller (extinct) tribes in Eastern Brazil, and was at the time of writing unaware of some other tribes which were uncontacted at that time. Currently only 200 nations (790 tribes) are alive, with no survivors being reported for the remaining nations. However, this doesn't mean their bloodlines are extinct; only their cultures. Brazilian Pardo and Mestizo population have mostly unknown indigenous backgrounds, some or several of them likely stemming from extinct cultures. The Bandeirantes hunted and enslaved indigenous peoples in the then unexplored interior of Brazil from the 16th to the early 19th century. The indigenous peoples were eventually acculturated and integrated into European civilization.

Most of the recorded extinctions of the Brazilian tribes were caused by warfare with the neo-Brazilians and from the epidemics which were sometimes deliberately spread by the colonizers. Intertribal warfare between various native Brazilian tribes also caused a significant number of extinctions. For example, the Matses, one of the tribes in the Vale do Javari region exterminated at least 4 smaller tribes during the 20th century.

Recent Extinctions

According to Darcy Ribeiro, a total of 87 tribes became extinct during the 1900-57 period. Another 38 became Assimilated (detribalized and merged in to the general population).

Recorded extinctions of Brazilian tribes during the 1900–1957 time period:

*Ribeiro grouped several nations into one in certain cases. For example, the Arara are actually 4 different tribes, which may or may not be linguistically and ethnically related. In such cases, the names of the known individual nations are given in Square Brackets.
In some cases, the tribes which were classified as extinct later re-emerged and exerted their identity. Examples are Krenak and Apiacá
In certain other cases, tribes which became extinct in Brasil existed as a living nation elsewhere, such as the Oyanpik
