Gjon  (definite form: Gjoni) is an Albanian male given name, clan, surname and onomastic element.

As given name

Etymology and history
Gjon as a given name is a form of the English name John. It is the name of the apostle Saint John in Albanian (). Most saint names in Albanian come from Latin;  John is from the Latin Iohannes, the Latin form of the  Greek Ioannes (), derived from the Hebrew name Yohanan (), meaning "God is gracious". Both theologists and linguists are unsure about the relationship of the name Gjon to Gjin—the Catholic clergy considers the two to be the same saint, but the Christians of the Central Albanian Shpati region (who are Orthodox) revere Gjin and Gjon as separate saints, while linguists are unsure about the etymology of Gjin and whether or not it shares its origin with Gjon.

In the Middle Ages the name Gjon was very widespread in all Albanian regions. Until lately it was also prevalent among Arvanites in Greece

The name Gjon is also mentioned in the afterword of Gjon Buzuku's 1555 book, Meshari, where the author introduces himself to the reader as "Unë, dom Gjoni, biri i Bdek Buzukut" ("I, don Gjoni, son of Bdek Buzuku").
