Anna Magdalene Thoresen, née Kragh (3 June 1819 – 28 March 1903) was a Danish-born Norwegian poet, novelist, short story writer and playwright.

She was a friend of Bjørnstjerne Bjørnson, who published her poetry collection Digte af en dame in 1860.

Among her novels are Studenten, published in the collection Fortællinger in 1862, Signes Historie from 1864, Min Bedstemoders Fortælling from 1867, and Solen i Siljedalen from 1868.

Among her successful plays are Et rigt Parti, which was first staged at the Royal Danish Theatre in 1870 and later in Stockholm and in Christiania, and Inden Døre from 1877.

[1][2] Thoresen's personality became a model for several female characters in Norwegian literature, including Ibsen's "Rebekka West" (from Rosmersholm) and "Ellida Wangel" (from The Lady from the Sea), and Bjørnson's "Maria Stuart" (from his 1864 play), the wild girl "Petra" from Fiskerjenten and "Leonarda" (from his 1879 play).
