Corinne is the French form of the Greek Korinna ("maiden") — the 5th-century BCE Greek poet from Tanagra in Boeotia (covered separately as Korinna). Corinne Olympios — Bachelor contestant. Saint Corinne is venerated in the French Catholic tradition.
Corinne 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 Corinne reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
