Pelin is the Turkish word for wormwood (Artemisia absinthium) — the bitter aromatic herb associated with Artemis. A poetic modern Turkish feminine name.
Pelin Karahan (born 1984) is the Turkish actress.
Pelin 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 Pelin reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
