Álvaro Fernandes (sometimes given erroneously as António Fernandes), is a 15th Century Portuguese slave-trader and explorer from Madeira, in the service of Henry the Navigator.
He captains two important expeditions (in 1445 and 1446), which expand the limit of the Portuguese discovery of the West African coast, probably as far as the northern borderlands of modern Guinea-Bissau.
Álvaro Fernandes's farthest point (c. Cape Roxo) would not be surpassed for ten years, until the voyage of Alvise Cadamosto in 1456.
