Beatriz is the Spanish and Portuguese form of Beatrice — from the Latin beatrix, meaning "bringer of joy" or "she who blesses." The same root gives the English "beatitude."
Beatriz is one of the most popular girl's names across the Spanish- and Portuguese-speaking world. In Italian literature, Beatrice was Dante's beloved muse in The Divine Comedy (her name spelled Beatrice in the original).
Beatriz 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 Beatriz reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
