Bipasha (বিপাশা) is the Bengali name for the Beas River — one of the five rivers of Punjab. Sacred in Hindu tradition, mentioned in the Rigveda.
Bipasha Basu (born 1979) is the Indian actress and former Miss India Universe.
Bipasha 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 Bipasha reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
