Reinaldo is the Spanish and Portuguese form of the Germanic name Reynold, itself derived from the elements ragin meaning 'advice' or 'counsel' and wald meaning 'ruler' or 'power'. The name was introduced to the Iberian Peninsula through the Visigoths and later reinforced by medieval French influence. It has been in use in Spanish-speaking countries since the Middle Ages, though less common in English-speaking regions.
