Navarius is of Latin origin, derived from the Roman family name Navius. It means "of Neptune" or "of the sea," after the Roman god of water and horses. The name was popular among Romans, especially during the empire's early years. Today, it's still used occasionally but remains somewhat rare, giving it a unique and distinctive sound.
Navarius was given to exactly five babies in the year 2007, with no occurrences since then.
