The turquoise tanager (Tangara mexicana) is a medium-sized passerine bird. This tanager is a resident bird from Trinidad, Colombia and Venezuela south to Bolivia and much of Brazil (despite its scientific name, it is not found in Mexico). It is restricted to areas with humid forest, with its primary distribution being the Amazon, while a disjunct population occurs in the Atlantic Forest of eastern Brazil. The latter population is sometimes considered a separate species, the white-bellied tanager (Tangara brasiliensis) .
