D. Álvaro da Costa (c. 1470–1540) was a Portuguese fidalgo, diplomat and close advisor to King Manuel I.

He is particularly well-remembered today for having filled the important court position of Chief Armourer of Portugal: the 1509 Livro do Armeiro-Mor (Book of the Chief Armourer), the most important Portuguese roll of arms in existence, is thus known for having been kept by Álvaro da Costa and his descendants. Also associated with him is the Da Costa Book of Hours, 1515, now in the Morgan Library and Museum in New York.
