Ingibiorg Finnsdottir (normalised Old Norse: Ingibjǫrg Finnsdóttir, Norwegian: Ingebjørg Finnsdotter) was a daughter of Earl Finn Arnesson and Bergljot Halvdansdottir.
The Orkneyinga Saga claims that Kalf Arnesson, Ingibiorg's uncle, was exiled in Orkney after her marriage to Thorfinn.
[4] Thorfinn and Ingibiorg had two known sons, Paul and Erlend Thorfinnsson, who jointly ruled as earls of Orkney.
[11] Ingibiorg is presumed to have died in around 1069 as Malcolm married Margaret, sister of Edgar Ætheling, in about 1070.
[13] If Ingibiorg was never queen, it would help to explain the apparent ignorance of her existence displayed by some Scots chroniclers.
