Naomi comes from the Hebrew Noʿomī (נָעֳמִי), meaning "pleasantness" or "sweetness" — derived from the root n-ʿ-m. In the Book of Ruth, Naomi is the mother-in-law of Ruth and grandmother of Obed (great-grandfather of King David). After tragedy, she asks to be called Mara ("bitter") instead of Naomi — but the original name is the one history remembers.
Naomi has been continuously used in Jewish communities for millennia and entered widespread Christian use through Puritan influence in the seventeenth century. Today it sits in the U.S. top 75 and is one of the most beloved biblical names that has not become tired through overuse.
Naomi 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 Naomi reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
