Vienna comes from the Latin Vindobona, the Roman name for the settlement that became the modern Austrian capital. The Celtic root vindo means "white" or "fair."
Vienna entered the U.S. top 1000 in 2014.
Vienna 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 Vienna reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
