Antoni is the Polish and Catalan form of Anthony, from the Roman family name Antonius, whose meaning is unknown; the popular reading "priceless" is a later folk etymology, as is the link to the Greek anthos, "flower". Architect Antoni Gaudí, creator of the Sagrada Família, is its most famous bearer. In the United States Antoni peaked at number 1563 in 2007 and ranks number 2286 in 2025.
