Athaliah (עֲתַלְיָה) is a Hebrew name meaning "God is exalted." In the Hebrew Bible, Athaliah was the daughter of Ahab and Jezebel who became queen of Judah and reigned for six years (2 Kings 11) — the only woman to rule Judah in her own right.
Athaliah is rare but distinctive.
Athaliah 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 Athaliah reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
