Bea is the diminutive of Beatrice — from the Latin beatrix, meaning "she who brings happiness" or "blessed." Used independently since the 19th century.
Bea has been rising rapidly in the 2020s as part of the broader return to vintage diminutives. The actress Bea Arthur (The Golden Girls) and Bea Smith (Wentworth) are notable bearers.
Bea 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 Bea reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
