Wiktoria is the Polish form of Victoria — from the Latin victoria, meaning "victory."
Wiktoria is among the most popular girls' names in modern Poland.
Wiktoria 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 Wiktoria reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
