Meaning & origin

Gregorio, the Italian and Spanish form of Gregory, has a long history in the United States but has never been among the most popular names. First recorded in Social Security data in 1880, it reached its peak rank in 1929, after which use gradually declined. It has been falling in popularity since 1993, with recent birth counts low. The name is most common in states with large Hispanic and Italian American communities, such as California, Texas, and Florida. Despite its relative rarity today, Gregorio remains a recognizable and culturally rich choice, especially among families with Italian or Spanish heritage.

Gregorio is the Italian and Spanish form of Gregory, which derives from the Late Latin name Gregorius, itself from the Greek Gregorios, meaning 'watchful' or 'alert.' The name was borne by several early Christian saints, including Pope Gregory I, and has been used throughout the Romance-speaking world since the Middle Ages.
