Ereshkigal (𒀭𒊩𒌆𒆠𒃲) is the Sumerian goddess queen of Irkalla, the underworld — elder sister of Inanna. Her name means "Queen of the Great Below." She rules the realm of the dead with implacable authority.
Featured in The Descent of Inanna, one of the oldest myths in human literature.
Ereshkigal 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 Ereshkigal reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
