Þórfinnr is an Old Norse masculine name, the direct forerunner of the later Scandinavian form Torfinn. The name is a compound of two elements: the first, Þórr, refers to the thunder god Thor (see Thor), from Proto-Germanic *Þunraz meaning "thunder"; the second element, finnr, means "Sámi, person from Finland" (finnr). Thus the name as a whole can be interpreted as "Thor's Finn" or "Finn of Thor."
In Norse mythology, Thor is one of the most prominent gods, a son of Odin, associated with storms, thunder, war, and strength. He is depicted as a red-bearded, short-tempered deity armed with the hammer Mjölnir and an enchanted belt that doubles his power. According to the mythological accounts, at Ragnarök Thor kills the world serpent Jörmungandr but succumbs to its venom. The inclusion of Þór- in personal names reflects the widespread veneration of this god across the Germanic world.
Names beginning with Þór- were especially common in medieval Scandinavia, and Þórfinnr is a characteristic example of the blending of pagan devotion with geographical or ethnic designations. The name first appears in runic inscriptions from the Viking Age, testifying to its pre-Christian usage. Vikings and settlers carried the name across the North Atlantic, occurring in Iceland, the Faroe Islands, and the Norse settlements in Greenland and the British Isles. In Iceland, the name is attested in Landnámabók, the Book of Settlements, as the name of early settlers.
Although the Old Norse form Þórfinnr eventually fell out of common use after the Christianization of Scandinavia, its descendant Torfinn survived, particularly in Norway and Iceland, and later enjoyed a moderate revival in modern times. The related name Þórr is a direct root, while other compounds with Thor (e.g., Þórsteinn, Þórvaldr) share similar cultural resonance.
Notable Bearers
While few historic individuals named Þórfinnr are recorded by name, Icelandic sagas mention a Þórfinnr Kárason, a Norwegian royal official in the early 11th century. Earldom candidates from Norse-turned-Norman lines occasionally Latinized their names as Turfinnus. The name is also identified in rune stones in Sweden, showing its spread outside Norway and Iceland.
Cultural Significance
As a compound name linking a major deity with an ethnic descriptor, Þórfinnr offers insight into Norse onomastic conventions that expressed identity, kinship, and fealty. Names invoking gods intended blessings upon the bearer, while finnr might reference participation in trade with the Sámi or voyages eastward — a term Finns and Sámi were often interchanged in early medieval sources.
