Acroá is an extinct Akuwẽ (Central Jê) language (Jê, Macro-Jê) of Brazil. It was spoken by the Acroá people around the headwaters of the Parnaíba and of the Paranaíba in Bahia, who were later settled in the missions of São José do Duro (Formiga) and in São José de Mossâmedes. The language went extinct before it could be documented; it is only known through a short wordlist collected by Carl Friedrich Philipp von Martius.[2]: 14 Due to an account of Martius' travels appearing in three large volumes from 1823 to 1831, the language probably went extinct sometime around then. Acroá is also known as Akroá, Acroamirim, Coroá and Koroá.[3]
