Caillou
Meaning of Caillou
Caillou is a French masculine name that literally means “pebble,” pronounced kai-YOO (/ka.ju/), and carries a gentle, unfussy quality. It first appeared in U.S. Social Security records in 2001 with 35 newborns (ranked 791) and has since maintained a quiet presence—most years seeing between five and twenty-odd births and generally hovering outside the top 800. While its rarity adds to its distinctive appeal, many English-speaking parents also recognize it from the long-running Canadian children’s series featuring a curious preschooler of the same name. With its straightforward sound and subtle literary and media associations, Caillou offers a grounded yet memorable choice for families seeking something both classic in origin and refreshingly uncommon.
