Ottine Caroline Emilie Andersen (1895–1970) was a Danish historian and archivist.
An intricate researcher, her first published work Grams Historie (1926) was a detailed history of the Gram Estate at Gram in the south of Jutland which she undertook for its owner Adolph Brockenhuus Schack.
After working for the Provincial Archives of Southern Jutland and then those of Zealand, in 1958 she was engaged by the National Archives where she developed a legendary competence in documenting historical records, in particular the archives of Christian II, integrating sources from Stockholm and Oslo.
The corresponding registry titled München-Samlingen was published in 1969 as Volume 15 of Vejledende Arkivregistraturer.
