Luca is the Italian and Romanian form of Luke, from the Greek Loukas, "from Lucania", and is often linked to the Latin lux, "light". It is a boys' name in Italy and Hungary, and in the United States Pixar's film Luca in 2021 gave it its biggest push. Luca rose from number 626 in 2000 into the top 100 in 2019 and ranks fourteenth in 2025.
