Duarte Barbosa (circa 1480, Lisbon, Portugal - 1 May 1521, Philippines) was a Portuguese writer and Portuguese India officer between 1500 and 1516-17, with the post of scrivener in the Cannanore Factory in India and sometimes interpreter of the local language (Malayalam). His "Book of Duarte Barbosa" (Livro de Duarte Barbosa) is one of the earliest examples of Portuguese travel literature, written circa 1516, shortly after his arrival in the Indian Ocean. In 1519 Duarte Barbosa embarked on the first expedition to circumnavigate the world, led by his brother-in-law Ferdinand Magellan, dying in 1521 at a feast held by the Rajah Humabon in Cebu in the Philippines.
