Hernando Arias de Saavedra (ārnän´dō ä´ryäs dā sävā´drä), known as Hernandarias (ārnändä´ryäs), 1561–1634, Spanish colonial governor, b. Asunción, in present-day Paraguay. An able administrator, he was elected (1592) lieutenant governor of Asunción by the cabildo and was chosen governor of Río de la Plata prov. three times (1597–99, 1602–9, 1614–18). He consolidated the Spanish settlements, pacified the Native Americans, introduced public schools, and stimulated the growth of Buenos Aires.
