Oddbjǫrg is an Old Norse feminine name, the historical spelling of the more modern Oddbjørg. It is composed of the elements oddr meaning "point of a sword" and bjǫrg meaning "help, salvation". The combination suggests a martial yet protective meaning: "sword-salvation" or "point-of-sword help".
Like many compound names from the Old Norse tradition, Oddbjǫrg exemplifies the Viking-era practice of crafting names from heroic and defensive concepts. The element odd (point, spearhead) appears in names like Oddr and Oddgeir, while bjǫrg (help, salvation) is found in female names such as Bjǫrg and Herbjǫrg.
The name is attested in Norse sagas and runic inscriptions, though it was never among the most common. Notable legend associates it with mythological or semi-legendary figures, highlighting that even rare compound names carried significant cultural weight among the Norse. During Christianization, many such Old Norse names gave way to saints’ names, preserving forms like Oddbjǫrg primarily in Scandinavian historical sources. In the modern era, forms like Oddbjørg see sporadic revival in Norway, furthered by local nicknames and literary uses.
