Agnar is a masculine given name of Old Norse origin, derived from the elements agi meaning "fear" or "terror" and her meaning "army." The name is often interpreted as "all-knowing" or "completely terrific." In modern times, the name is relatively rare but has been used in various cultures, particularly in Scandinavian countries. The Hebrew translation of Agnar is אָגְנָר (pronounced "Ag-nar"). In other languages, the name may be rendered as Agnarr in Icelandic and Agnar in Norwegian and Swedish. The name has historical significance, as it was borne by several figures in Norse mythology and sagas, including Agnarr, a king of Sweden mentioned in the Ynglinga Saga.
