The Portuguese conquest of Maranhão took place between 23 August 1612 and 3 November 1615, in the state of Maranhão, Brazil, between Portuguese and Tabajara forces, on the one hand, and French and Tupinambá forces, on the other. The campaign resulted in the definitive expulsion of the French from Maranhão on November 4, 1615.

The expulsion of the French allowed a large part of the Amazon to fall under Portuguese dominion.
