History & Origin

Ioannis is the Greek John — descended from Hebrew Yochanan, 'God is gracious', via the New Testament's Ioannes, the form behind every European John from Juan to Ivan. Greece keeps it among its most common men's names, with name-day celebrations each January; Yannis and Giannis are its working nicknames.

Basketball superstar Giannis Antetokounmpo introduced America to the nickname; the formal Ioannis remains rare stateside, a passport-stamped classic for Greek-American families.

Did you know? When you read 'John' in the New Testament, the Greek text says Ioannes — meaning this 'exotic' name is the most textually authentic John there is.
