Mireia is the Catalan form of the Provençal Mirèio — derived from the Occitan mirar, meaning "to admire" or "to wonder at." The name was popularised by Frédéric Mistral's 1859 epic poem Mirèio, written in Provençal — for which he received the Nobel Prize in Literature in 1904.
Mireia is widely used in Catalonia, Spain, and parts of southern France. It is rising slowly in Western records. Three lyrical syllables and a Nobel-laureate-attributed origin.
Mireia 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 Mireia reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
