Klasson is a Swedish surname meaning "son of Klas". The name Klas is a Swedish short form of Nicholas, so Klasson ultimately derives from the Greek Nikolaos, meaning "victory of the people".Etymology and HistoryThe surname belongs to the widespread Scandinavian tradition of patronymic names—formed by adding -son (or -sson) to a father's given name. In Sweden, -son surnames became hereditary from the 19th century onward. The shorter form Klas, as opposed to Niklas or Nils, was historically common in southern and central Sweden.Notable BearersWhile Klasson is less common than variants like Niklasson (which preserves the full Nicola form), it appears in Swedish records since at least the 17th century. Notable modernbearers include Swedish footballer Oscar Klasson (born 1986) and artist Monika Klasson (born 1965). Karin Klasson (191.???—1959) was a Swedish physicist remembered for research in optics.DistributionForebears ranks Klasson as the 9,430th most common surname globally, with approximately 2,000 bearers—(https://forebears.io/surnames/klasson).
