Guaianases is one of 96 districts in the city of São Paulo, Brazil. The Guaianases district was formed in the same way as Itaquera: both were born from indigenous settlements and from the efforts of the Jesuits, especially Father Manuel da Nóbrega and José de Anchieta, who founded the Jesuit school for the catechism of the Guaianás. The settlement continued, but "by around 1820 the Indians were already extinct and the land was in private hands".
