Waitaká (Guaitacá Goyatacá Goytacaz) is an extinct and unclassified language of Brazil (Campbell & Grondona 2012) on the São Mateo River and near Cabo de São Tomé in the state of Rio de Janeiro. Dialects or at least tribal divisions were Mopi Yacorito Wasu and Miri. Loukotka (1968) suggests it may have been one of the Purian languages.
