Meaning & Origin
Kolsen is a boy's baby name of Scandinavian origin, a variant of Colsen or Kolsen, from the Norse surname tradition meaning 'son of Kol' — where Kol is a short form of names meaning 'dark' or 'charcoal,' from Old Norse kol.
A rare surname-name with Norse heritage, Kolsen has the clean, distinctive quality of Scandinavian surnames that have made the crossover into first-name territory. It sounds strong and crisp, with the double-syllable rhythm that fits naturally in contemporary American naming.
