Pedro Mascarenhas (1470- June 23, 1555) was a Portuguese explorer and colonial administrator.
The first Europeans to discover the Seychelles were Vasco da Gama in 1502 and Pedro de Mascarenhas 1505.
Mascarenhas was the first European to discover the island of Diego Garcia in the Indian Ocean in 1512. He also encountered the Indian Ocean island of Mauritius in 1512, although he may not have been the first Portuguese explorer to do so; earlier expeditions by Diogo Dias and Afonso de Albuquerque may have encountered the islands.
In 1528 explorer Diogo Rodrigues (after whom the island of Rodrigues is named) named the islands of Réunion, Mauritius, and Rodrigues the Mascarene Islands, after Mascarenhas.
Mascarenhas served as Captain-Major of the Portuguese colony of Malacca from 1525 to 1526, and as viceroy of Goa, capital of the Portuguese possessions in Asia, from 1554 until his death in 1555. He was succeeded as viceroy by Francisco Barreto.
