Renauld is of French origin, derived from the Germanic given name Rainald, which was formed from the elements ragin, meaning "counsel" or "advice," and wald, meaning "rule." It gained popularity in France through the Normans who brought it over during their rule. The name reached its peak usage in France during the 19th century but has since become less common.
Renauld has seen a fluctuating number of births over the years, with peaks in 1970 and 1978, and lower numbers in between.
