António Cordeiro (c.1641; Angra – 2 February 1722; Lisbon) was a Portuguese Catholic priest in the Society of Jesus, Azorean historian, author of the classical chronicle Historia Insulana, and first to publish a public opinion on the form of governance for the archipelago of the Azores.
Aside from being physically punished, he was brought before the supreme commander of Spanish forces, the Duke of Medinaceli, who was impressed by his brilliant oratory, and granted him safe passage to Portugal.
In addition to his work as professor in the Society of Jesus, he was a renowned orator, who traveled between dioceses in catechism missions and introducing reforms organized by the Jesuits; he was a regular on the "circuit" between Braga, Viseu, Pinhel, Torres Novas and other places.
D. José de Barbosa, on the publication of Cordeiro's História Insulana affirmed: He dedicated himself to the history of the Azores, aided by the manuscripts of Gaspar Frutuoso, which were held in the possession of the Society of Jesus.
It was the first work to be edited, and published: it became a fundamental text on Azorean history, even as Frutuoso's Saudades da Terra was inaccessible and parts uncompleted until the end of the 20th Century.
