Helia (Ἡλία) is the Greek feminine of Helios, the personification of the sun. The name simply means "sun" or "of the sun."
Helia is rare but rising as part of the broader return of Greek mythological names.
Helia 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 Helia reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
