The Dois Paus redoubt (Portuguese: Reduto dos Dois Paus) is a redoubt fortification situated on the peninsula of Monte Brasil, in the civil parish of Sé, in the municipality of Angra do Heroísmo, in the Portuguese archipelago of the Azores.

It was part of the fortified defenses of the Fortress of São João Baptista.

Bartolomeu Ferraz first presented his recommendations to John III of Portugal in 1543 for the fortification of the Azores, then an important waypoint in trans-Atlantic commerce between the Indies and America.

[1] On 5 March 1567, in his proposal to the Crown, Engineer Tommaso Benedetto elaborated a plan to protect the island's coastal defence, that included the construction of a fort on Monte Brasil.

In the context of the Captaincy-General of the Azores, there was a reference to the structure, stating in 1767: Its remains continue to lie on the volcanic cone of Monte Brasil to this day, in ruins.
