Elíasson

Elíasson is an Icelandic patronymic surname meaning "son of Elí" (or Eli). It is formed from a given name plus the Icelandic suffix -asson, which indicates a paternal lineage. In Iceland, such names commonly function as patronymics rather than fixed family surnames; they typically denote the father’s name and change with each generation rather than being inherited by all siblings.

Spelling and usage vary in practice. The Icelandic form Elíasson retains the diacritic on the i, while anglophone contexts often render the name without diacritics as Eliasson. As a result, individuals with this name may appear under slightly different spellings in different records. Outside Iceland, the surname is relatively rare and may be found among emigrant communities or in contexts where Icelandic naming conventions are less strictly followed.

Notable people with the name include Olafur Eliasson (born 1967), an Icelandic-Danish contemporary artist known for large-scale installations that explore perception, light, and environmental phenomena. The name can appear among people of Icelandic heritage in various countries, reflecting the broader diaspora of Icelandic naming practices.
