En-haddah is a place name meaning perhaps 'swift spring' or 'sharp spring,' combining 'en' (spring/fountain) with an adjective suggesting quickness or sharpness. It was a town within the tribal allotment of Issachar, appearing in the boundary list in Joshua 19. The exact location is unknown, though it was somewhere in the Jezreel valley region or surrounding hills where Issachar settled. Springs were vital for settlement in ancient Israel, and towns were often named after their water sources. The adjective 'haddah' (sharp/swift) may describe the spring's rapid flow or the quality of its water. The Septuagint's Greek transliteration shows uncertainty about the original pronunciation. Like many biblical place names, En-haddah survives only in this boundary list.
