Rex

Boy name · 138 babies recorded · 1974–2025

Rex: 138 babies born in Scotland since 1974, given to boys, peaking at 22 births in 2020.

The name Rex has a direct and powerful origin, coming directly from the Latin word for "king," a title that was used in ancient Rome and later adopted as a given name. Its most famous modern bearer was the swashbuckling Hollywood actor Rex Harrison, who immortalised the name in classic films like *My Fair Lady*. The name also appears frequently in the natural world, most notably as the king of dinosaurs, *Tyrannosaurus rex*. The most prominent place connection is the Scottish town of Rex; however, no such place exists, though Rex is the name of several small settlements in the United States. A short, punchy, and authoritative classic, Rex is a name that has seen consistent but modest use in Scotland, often chosen by parents who appreciate its regal, no-nonsense feel.
