(male) English form of Latin Io(h)annes, New Testament Greek Iōannēs, a contracted form of the Hebrew name Johanan ‘God is gracious’ (the name of several different characters in the Old Testament, including one of King David's ‘mighty men’). John is the spelling used in the Authorized Version of the New Testament. The name is of great importance in early Christianity: it was borne by John the Baptist (the precursor of Christ himself, who baptized sinners in the River Jordan), by one of Christ's disciples (John the Apostle, a fisherman, brother of James), and by the author of the fourth gospel (John the Evangelist, identified in Christian tradition with the apostle, but more probably a Greek-speaking Jewish Christian living over half a century later). The name was also borne by many saints and by twenty-three popes, including John XXIII (Giuseppe Roncalli, 1881–1963), whose popularity was yet another factor influencing people to choose this given name. It was also a royal name, being borne by eight Byzantine emperors and by kings of Hungary, Poland, Portugal, France, and elsewhere. Among numerous bearers of note in recent times have been American president John F. Kennedy (1917–63) and British pop singer John Lennon (1940–80). In its various forms in different languages, it has been the most perennially popular of all Christian names.

English (East Midlands): from the Middle English personal name Thurmond, Old Norse þormundr, composed of the elements þórr, name of the Norse god of thunder (see Thor) + mundr ‘protection’. Reaney and Wilson suggest that, Thurmond having been an uncommon personal name, this surname may also represent the commoner name Thurmod, Thormod with the second element derived from Old Norse móþr ‘mind’, ‘courage’, but assimilated to -mund (a common second element in other compound names).
German (Thurmann): habitational name for someone from a place called Thur (see Thur).
