Gaius Origin and Meaning

The name Gaius is a boy's name of Latin origin meaning "to rejoice".

Stately Gaius (pronounced GUY-us) was in the name of many ancient Romans, including Julius Caesar. Little-used before the year 2000, it now feels like a fresh possibility in the revival of Latin boys' names like Atticus and Cassius. Caius and derivatives like Caio come from the same root. You could also see Gaius as a male version of the earth-goddess name Gaia.
