Indrani (इन्द्राणी) is the feminine of Indra — "queen of Indra." Wife of Indra, king of the Vedic gods — also called Shachi ("power"). Mother of Jayanta and Jayanti; her temple at Indrani in Maharashtra is a renowned pilgrimage site.
Indrani 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 Indrani reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
