Meaning & Origin
A male given name from Latin, in occasional use.
Octavius is a boy's and girl's baby name of Latin origin, from the Latin octavus, meaning 'eighth.' It was a Roman family name of the Octavii clan, most famously borne by Gaius Octavius — who became Augustus Caesar, the first Roman Emperor and one of history's most consequential rulers.
With over 3,600 U.S. births, Octavius has a majestic Roman grandeur — it is a name that carries the weight of empire, the elegance of classical antiquity, and an unmistakable sense of destiny.
