Iversen (Danish pronunciation: [ˈiˀvɐsn̩]) is a Danish-Norwegian patronymic surname meaning "son of Iver", from the Old Norse personal name Ívarr. The Old Norse personal name is composed of the two elements: either ív meaning "yew tree", "bow" or Ing (an old Germanic God); and the element ar meaning "warrior" or "spear". Scandinavian immigrants to English-speaking countries often changed the spelling to Iverson in order to accommodate English orthographic rules. People. Baard Iversen (1836–1920), Norwegian businessperson and politician.
