Meaning & origin

Basilio has been in use in the United States since at least 1904, when it first appeared on the Social Security Administration's records. That first year was also its peak year, though it has remained a very rare choice. As of 2025, the name ranks 7,679, with roughly 1 in 170,808 male newborns receiving it. The name has been on a rising trajectory since 2017, suggesting a modest revival. Basilio is the Italian, Spanish, and Portuguese form of Basil, connecting it to a wide European tradition. For families seeking a name with a strong, regal meaning and a melodic sound, Basilio offers an uncommon but recognizable option.

Basilio is the Italian, Spanish, and Portuguese form of Basil, which derives from the Greek name Basileios, meaning 'kingly' or 'royal.' The Greek root 'basileus' means 'king.' The name has been used in various Christian cultures, often in honor of saints such as Saint Basil the Great.
