Duarte Barbosa (Portugal - † 1521, Philippines) was a Portuguese writer and Portuguese India officer between 1500 and 1516–17, with the post of scrivener in Cannanore factory 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 the 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 the feast of rajah Humabon in Cebu at the Philippines.
