Álvaro Velho (15th-16th century, born in Barreiro, Portugal) was a Portuguese sailor or soldier who took part in the first Portuguese expedition by sea to India, led by Vasco da Gama in 1497.
Velho is one of the purported authors of the anonymous Journal of Vasci Da Gama's trip of 1497 (the other being João de Sá).
In 1945, historian Franz Hümmerich identified the author of this manuscript with an Álvaro Velho who had spent eight years in Guinea and provided information about the Gambia region to Valentim Fernandes.
However, more recent studies by Carmen Radulet have exposed weaknesses in this theory and attributed the Journal with more certainty to scrivener João de Sá.
