Meaning & origin

Pio is a name with deep Latin roots, meaning 'pious' or 'devout'. It has been used in Italy and Spain for centuries, often in honor of Pope Pius, and first appeared in U.S. records in 1916. Despite its long history, it remains uncommon: as of 2025, it ranks 4,396th in popularity, with a frequency of about 1 in 74,264 male births. The name saw its peak year in 2025, and its trajectory suggests stability rather than a dramatic rise or fall. Its rarity may appeal to families seeking a distinctive name with strong religious and cultural resonance.

Derived from the Latin 'pius', meaning 'pious' or 'devout'. It has been used as a given name in Italy and Spain, often in honor of Popes named Pius, including Pope Pius X (born 1835). The name became particularly common in Italian communities but remains relatively rare in English-speaking countries.
