Rex is Latin in Origin.

Rex derives from Latin rex, genitive regis, "king," from the Proto-Indo-European root reg- "to rule, straighten, guide." The word functioned for centuries as a sovereign’s title in Roman and medieval Latin contexts, echoed on coins, charters, and mottos, which lends the name an unmistakably regal tone.

As a given name, Rex gained currency in the English-speaking world from the late 19th century, peaking mid-20th and enjoying a modern revival for its crisp, confident sound. Well-known bearers include actor Rex Harrison and mystery writer Rex Stout. Variants and cognates by language or meaning include Regis (French/Latin), Rey (Spanish), Roi/Roy (Old French into English), and the compound Leroy; semantic counterparts are King and Kingston, while Rexford is a surname-based elaboration. A feminine cognate is Regina. Rex is also sometimes adopted as a nickname for Reginald or other names in the reg- family.
