Meaning & origin

Tavius is an uncommon given name in the United States, first recorded in 1974. It has never entered widespread use; its peak popularity occurred in 1999, after which its frequency has declined. As of 2025, approximately 1 in 244,011 newborns receive the name, placing it at rank 9,714. The name's origins are unclear, but it likely emerged as a modern variant of Octavius or as a shortened form of names like Octavio. Despite its obscurity, Tavius has a melodic, three-syllable sound that fits with contemporary trending names ending in -ius, such as Julius or Cassius.

Tavius first appeared in U.S. records in 1974. It is likely a modern coinage, possibly as a given-name form based on the Latin surname Octavius (meaning 'eighth') or as a variant of the Spanish and Italian name Tavio, which itself may derive from Octavio. The name has seen sporadic use in the United States, peaking in 1999.
