Luigi is the Italian form of Louis, which comes from the Germanic Hludwig and means "famous warrior". It was the name of the composer Luigi Boccherini and the playwright Luigi Pirandello, but to American children it belongs above all to Mario's taller brother in Nintendo's video games. Luigi ranked number 1795 in 2000, its best recent position, and stands at number 2554 in 2025 after a small uptick since 2023.
