Iro (Ηρώ) is the modern Greek pronunciation of Hera — queen of the Olympian gods, wife of Zeus. Among the most poetic modern Greek feminine names.
Featured in modern Greek literature.
Iro 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 Iro reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
