Margaux is a stylish French form of Marguerite, and so of Margaret, meaning a pearl.
It carries an air of Bordeaux and vineyards, echoing the famous Château Margaux, and was memorably borne by the model Margaux Hemingway. The result is a name that feels both refined and a little bohemian.
For parents who love Margaret's meaning but want something chicer, Margaux is the pearl reset in modern gold.
Margaux does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Margaux reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
