Björnsson

Björnsson is a patronymic surname meaning "son of Björn". It originates from the given name Björn, which derives from the Old Norse word bjǫrn, meaning "bear". The name reflects the common Nordic tradition of constructing surnames by adding -son (or -sen in Danish and Norwegian) to the father's name. Variants include Bjarnesen (Danish), Bjørnson/Bjørnsen (Norwegian), and Bjornsen (nonstandard).

In Iceland, the surname Björnsson follows the Icelandic patronymic system, where family names are rarely fixed; instead, children take their father's name with the suffix -son (son) or -dóttir (daughter). However, Björnsson also exists as a fixed family name in some cases.
