Annalisa is the Italian compound of Anna (grace) and Lisa (short for Elisabetta, "my God is an oath"). A traditional Italian feminine name.
Annalisa Scarrone (born 1985) is the Italian pop singer known mononymously as Annalisa.
Annalisa 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 Annalisa reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
