Fidalgo (, ), from Galician and Portuguese —equivalent to a nobleman, but sometimes literally translated into English as "nobleman" —is a traditional title of Portuguese nobility and Brazilian nobility that refers to a member of the titled or untitled nobility. A fidalgo is comparable in some ways to the French gentilhomme (the word also implies nobility by birth or by charge), and to the Italian nobile but having a higher rank to the British baronet as being a part of the aristocracy, not a commoner. The title was abolished after the overthrow of the monarchy in 1910 by the republic and is also a family surname.
