Catalina is the Spanish and Catalan form of Catherine — from the Greek katharos, meaning "pure." Catalina Island off the coast of southern California is named after Saint Catherine of Alexandria.
Catalina has been climbing rapidly in the U.S. since the 2010s. Today it sits in the U.S. top 350.
Catalina 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 Catalina reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
