Lior (לִיאוֹר) is a Hebrew name composed of li (to me, mine) and or (light) — meaning "my light." Used for both boys and girls in modern Israel, with the feminine form Liora more common for girls in the diaspora.
Lior is rising in the U.S. and Israel. The Australian-Israeli singer Lior Attar is a male bearer.
Lior 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 Lior reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
