In Brazil, an Indigenous territory or Indigenous land (Portuguese: Terra Indígena [ˈtɛʁɐ ĩˈdʒiʒẽnɐ], TI) is an area inhabited and exclusively possessed by Indigenous people. Article 231 of the Brazilian Constitution recognises the inalienable right of Indigenous peoples to lands they "traditionally occupy" and automatically confers them permanent possession of these lands.
A multi-stage demarcation process is required for a TI to gain full legal protection, and this has often entailed protracted legal battles. Even after demarcation, TIs are frequently subject to illegal invasions by settlers and mining and logging companies.
