Ingibiorg Finnsdottir (normalised Old Norse: Ingibjǫrg Finnsdóttir, Norwegian: Ingebjørg Finnsdotter) was a daughter of Earl Finn Arnesson and Bergljot Halvdansdottir.  She was also a niece of the Norwegian Kings Saint Olaf and Harald Hardraade. She is also known as Ingibiorg, the Earls'-Mother. The dates of her life are not known with certainty.
She married Thorfinn Sigurdsson, Earl of Orkney. The Orkneyinga Saga claims that Kalf Arnesson, Ingibiorg's uncle, was exiled in Orkney after her marriage to Thorfinn. This was during the reign of Magnus the Good, son of Saint Olaf, who ruled from 1035 to 1047, and probably before the death of Harthacanute in 1042. Thorfinn and Ingibiorg had two known sons, Erlend Torfinnsson and Pål Torfinnsson, who jointly rules as Earls of Orkney. Both also fought in Harald Hardraade's ill-fated invasion of the Kingdom of England in 1066.  
Ingibiorg remarried after Thorfinn's death (actual date unknown)  Her second husband was Malcolm III (Máel Coluim mac Donnchada), the King of Scots. Whatever the exact date of the marriage, Malcolm and Ingibiorg had at least one son, and probably two. The Orkneyinga Saga tells us that Duncan II of Scotland (Donnchad mac Mail Coluim') was their son, and it is presumed that the "Domnall son of Máel Coluim, King of Scotland" whose death in 1085 is reported by the Annals of Ulster was also their son.
Ingibiorg is presumed to have died in around 1069 as Malcolm married Margaret, sister of Edgar Ætheling, in about 1070. It may be, however, that she died before Malcolm became king, as an Ingeborg comitissa appears in the Liber Vitae Ecclesiae Dunelmensis, a list of those monks and notables from whom prayers were said at Durham, alongside persons known to have died around 1058. If Ingibiorg was never queen, it would help to explain the apparent ignorance of her existence displayed by some Scots chroniclers.

- Orkneyinga Saga, c. 32, says that he "died towards the end of the reign of Harald [Hardraade]". Harald reigned for twenty years. See also Duncan, p. 42, who suggests Thorfinn died in the early 1050s.
