French word meaning 'handsome' or 'beautiful,' used as a given name since the 18th century.
Beau is a French word meaning "beautiful" or "handsome," from the Latin bellus, meaning "pretty" or "fine." Unlike many names with ancient saintly or royal pedigrees, Beau began as an epithet and term of admiration before settling into use as a personal name. In English, the word long carried a social meaning as well: a beau was a suitor, escort, or fashionable gentleman.
That layer of meaning gave the name an immediate air of charm, polish, and easy confidence. One of its most famous cultural echoes is Beau Brummell, the early nineteenth-century English dandy whose surname became synonymous with elegance and male fashion, even though Beau in his case was a nickname-title rather than a given name. In the American South and Southwest, Beau gradually took root as a given name, helped by its brevity, French flavor, and smooth, masculine image.
It has also appeared in popular culture through characters in novels, film, and television, often attached to charismatic or romantic figures. Over time, Beau has shifted from seeming slightly regional or rakish to feeling stylishly mainstream. It fits modern tastes for short, vowel-rich, understated names, and it carries an unusual duality: softness in sound, confidence in meaning.
While it is often read as distinctly masculine in English-speaking countries, its origin in an adjective gives it a lighter, more fluid history than many traditional boys' names. Today Beau suggests warmth, charm, and polish without sounding fussy, which helps explain its rising appeal.
