Javan (Hebrew יָוָן, Standard Hebrew Yavan, Tiberian Hebrew Yāwān) was the fourth son of Noah's son Japheth according to the "Table of Nations" (Genesis chapter 10) in the Hebrew Bible. Flavius Josephus states the traditional belief that this individual was the ancestor of the Greek people.
Also serving as the Hebrew name for Greece or Greeks in general, יָוָן Yavan or Yāwān has long been considered cognate with the name of the eastern Greeks, the Ionians (Greek Ἴωνες Iōnes, Homeric Greek Ἰάονες Iáones; Mycenean Greek *Ιαϝονες Iawones). The Greek race has been known by cognate names throughout the Eastern Mediterranean, Near East and beyond—even in Sanskrit ( yavana). In Greek mythology, the eponymous forefather of the Ionians is similarly called Ion, a son of Apollo. The opinion that Javan is synonymous with Greek Ion and thus fathered the Ionians is common to numerous writers of the early modern period including Sir Walter Raleigh, Samuel Bochart, John Mill and Jonathan Edwards, and is still frequently encountered today.
