Xenia (Ξενία) comes from the Greek xenos, meaning "guest" or "stranger" — and the abstract noun xenia, which refers to the ancient Greek concept of sacred guest-friendship: the moral obligation of hosts to welcome strangers, considered a fundamental virtue.
Xenia is widely used in Russia and Greece. In the U.S. it remains rare but distinctive.
Xenia 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 Xenia reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
