Nukini (Nukuini, Nuquini) is an obsolescent Panoan language of Brazil. In some historical texts the Nukini are also referred to as Inucuini, Nucuiny, Nukuini, Nucuini, Inocú-inins and Remo.
As a result of contact with outsiders, there are currently few who speak Nukini as a mother tongue. The Nukini stopped passing on the language to their descendants, and the current generation speaks Portuguese. The language has been taught in schools since 2000.
The language uses 18 letters.
