Guató is a possible language isolate spoken by 1% of the Guató people of Brazil. Kaufman (1990) provisionally classified it as a branch of the Macro-Jê languages, but no evidence for this was found by Eduardo Ribeiro.

The Guato vowel system, like that of Macro-Jê languages, collapses a three-way distinction of height in oral vowels to two in nasal vowels.
