Caius Origin and Meaning

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

Caius is classical and serious but also has a simple, joyful quality. There was a third century pope named Caius, as well as an early Christian writer, several Shakespearean characters, and a Twilight vampire. We would pronounce the name to rhyme with eye-us though at Cambridge University in England, where it's the name of a college, it's pronounced keys.

Nickname Cai is a definite asset.
