Arturo is the Spanish and Italian form of Arthur, a name of uncertain origin that is usually traced to the Celtic artos, "bear", or to the Roman family name Artorius. The conductor Arturo Toscanini carried it to America, and it remains a traditional choice in Mexican-American families. Arturo ranked number 291 in 2000, peaked at number 284 in 2001 and has eased to number 627 in 2025.
