Araújo or Araujo or Arauxo is a Galician and Portuguese surname. The surname Araújo is of toponymic origin derived from a place in the Province of Ourense which is part of the Autonomous Community of Galicia in North Western Spain next to the Portuguese border where a Crusader Knight of French Noble descent, Don Rodrigo Anes, was rewarded with reconquered Iberian lands during the Reconquista. Don Rodrigo Anes de Araújo lived in the 14th century during the reign of King Ferdinand I of Portugal (1367-1383). Don Rodrigo Anes de Araújo built a Castle and named it Araújo which can be found in all the ancient Galician maps.
