Ivarsson

Ivarsson is a Swedish patronymic surname meaning "son of Ivar." It originates from the given name Ivar, a common Old Norse personal name, and follows the traditional Nordic naming pattern in which -sson denotes "son of." Historically, Ivarsson would identify someone as the child of a man named Ivar; in modern times, it functions as a fixed family surname rather than a direct indicator of paternity.

The surname is most prevalent in Sweden, where it ranks among the more common family names. It is also found among Finnish populations with Swedish heritage and within other Nordic communities. Variants and related surnames include Iversen, common in Denmark and Norway, and Iverson, an anglicized form found in English-speaking countries. Other transliterations or spellings exist in immigrant contexts, reflecting adaptation to local languages.

Notable individuals bearing the name span various fields, including sports, academia, and the arts, reflecting the broader distribution of the surname rather than a single lineage. As with many Nordic patronymics, Ivarsson represents both a historical naming convention and a modern, inherited surname.
