Feliu is the Catalan form of the Latin name Felix, which derives from the Roman cognomen meaning "lucky, successful". The name was popularized as an agnomen by the 1st-century BC Roman general Sulla, who adopted it after his military successes. In the New Testament, Felix appears as the governor of Judea who imprisoned Saint Paul (Acts 23–24). Early Christians favored Felix for its auspicious meaning, leading to many early saints and four popes bearing the name. While Felix has been used throughout Europe, Feliu specifically emerged in the Catalan-speaking regions, where it has been in use since the Middle Ages. Until the 20th century, it was primarily given in its original Latin form, but Feliu has persisted as a distinct local variant. Although less common today, Feliu remains a recognized given name in Catalonia, Valencia, and the Balearic Islands. It may also appear as a surname in some contexts. Related forms in other languages include Felix (Swedish), Félix (Spanish), Felice (Italian), Feliks (Slovene), and the Biblical Greek Phelix.
