Anna Olsson (19 August 1866, Värmland, Sweden – 15 February 1946, Rock Island, Illinois) was a Swedish-American author.

Olsson's father accepted a professorship at Augustana College and Theological Seminary in 1877, and the family moved to Rock Island, Illinois.

[3] During this trip, Olsson continued her education in a German school and attended literature and philosophy lectures at the University of Zurich.

[1] According to a report prepared to designate her home as a historic landmark, Olsson was "as well known as Mark Twain and Harriet Beecher Stowe for her children's books," although literary scholar Ann Boaden places her fame at a more moderate level.

[5][6] En prärieunges funderingar, the book she is best known for, is a semi-autobiographical work about her family's immigration to the United States and their years living on the Kansas prairie.

[2] Olsson was also a popular contributor to Swedish and Lutheran periodicals, publishing her work in Ungdomsvännen, Fosterlandel, Prairieblomman, Julrunan, and Julgranan, among others.

Prärieungen: Anna Olssons barndomsminnen, an abbreviated version of En prärieunges funderingar, was published by Joan Sandin in 1984 (Stockholm: Rabén & Sjögren, ISBN 9789129564037).
