jùn

Jón is a masculine given name in Icelandic and several North Atlantic cultures. It is the Icelandic form of John, itself derived from the Hebrew Yochanan, commonly translated as "God is gracious" or "the Lord is gracious."

Jón is usually written with an acute accent on the o, as in Jón, and is pronounced roughly "YOHN." In Iceland, it is one of the most common given names, both in historical records and in contemporary use.

Icelandic naming conventions typically use patronymic or matronymic surname forms rather than fixed family names. A man named Jón would ordinarily be identified by his given name followed by a patronymic, such as Jónsson for a son of Jón or Jónsdóttir for a daughter of Jón, rather than a traditional surname.

Notable people named Jón include Jón Sigurðsson (1811–1879), a leader of the Icelandic independence movement; and Jón Gnarr (born 1967), a comedian, writer, and former mayor of Reykjavík. Other Icelandic figures with the name include the composer Jón Leifs (1894–1968) and various politicians and athletes.

Jón is closely related to the wider name John, with cognates in many languages, including Jón in Icelandic, Johan in Dutch and Norwegian, and Ioannes in Greek.
