Reina is from the Spanish reina (queen) — from the Latin regina. Reina Caponi — modern Argentine figure. Reina Roffé — Argentine novelist. Reina Pelaez — modern American figure. Hotel Reina Sofía — historic Madrid landmark. La Reina (album) — Karol G's 2024 release.
Reina 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 Reina reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
