Fidalgo, from Galician fillo de algo and Portuguese filho de algo—equivalent to nobleman, but sometimes literally translated into English as "son of somebody" or "son of some "—is a traditional title of Portuguese nobility that refers to a member of the titled or untitled nobility. A fidalgo is comparable in some ways to the French gentilhomme and to the Italian nobile. The title was abolished after the overthrow of the Monarchy in 1910. It is also a family surname.
