Adina (עֲדִינָה) is a Hebrew name meaning "delicate," "refined," or "gentle." The masculine Adin appears in the Hebrew Bible (Ezra 2:15).
Adina is widely used in modern Israel and in observant Jewish families across the diaspora.
Adina 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 Adina reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
