Meaning & origin

Lucius is a masculine name of Latin origin meaning 'light.' After its peak in 1881 (rank 1128), it declined but has been rising again since 1994. In 2025, it ranked 1128th with about 1 in 9,037 boys receiving the name. It remains most strongly associated with states like Iowa, Kansas, and Washington. The name's steady revival reflects a broader interest in classical Roman names, offering a distinguished yet accessible choice for modern parents.

Lucius is a Latin praenomen (given name) derived from 'lux' (light). It was common in ancient Rome, borne by several notable figures including Lucius Junius Brutus, the founder of the Roman Republic, and Lucius Cornelius Sulla, a Roman general. The name continued in use through the medieval period and into the Renaissance, and was revived in the 19th century.
