Marisa is the Italian and Spanish contraction of Maria-Luisa — also linked to the Latin mare (sea), interpreted as "of the sea."
Marisa Tomei (born 1964) is the American Oscar-winning actress; Marisa Berenson (born 1947) is the American model and actress.
Marisa 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 Marisa reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
