Meaning & origin
Justo is a Spanish name that has never gained widespread popularity in the United States. It first appeared in U.S. birth records in 1890 and reached its peak rank that same year, placing among the bottom of the charts. Since 1985, its usage has been on a declining trajectory. In 2025, the name ranked 8,910th with an estimated 1 in 213,510 newborns receiving the name. The name is almost never given to girls. While top states for its use are not recorded, Justo remains a rare but meaningful choice for families seeking a virtue name with Spanish heritage.
Justo is the Spanish form of the Latin name Iustus, which means 'just' or 'righteous.' It was borne by several early Christian saints, including Saint Justus of Canterbury, a 7th-century archbishop. The name has been in steady use in Spanish-speaking countries, though it has never been common in the United States.
