Rosalia comes from the Latin rosa, the rose, and echoes an ancient Roman festival of roses. It is best known as the name of Saint Rosalia, the beloved patron of Palermo, whose feast fills the Sicilian streets each summer.
Lush and Mediterranean, it has recently gained fresh glamour through the acclaimed singer Rosalía.
Floral, warm and a little dramatic, Rosalia is a rose in full bloom.
Rosalia 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 Rosalia reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
