Elin Matilda Elisabet Wägner (16 May 1882 – 7 January 1949) was a Swedish writer, journalist, feminist, teacher, ecologist and pacifist.

Among Wägner's most popular novels — which continue to be read — are: Norrtullsligan ("Men and Other Misfortunes", 1908), Pennskaftet ("The Penholder", 1910), Åsa-Hanna (1918), Kvarteret Oron ("Stormy Corner", 1919), Silverforsen ("The Silver Rapids", 1924), Vändkorset ("The Turnstile", 1934), Väckarklocka ("Alarm Clock", 1941) and Vinden vände bladen ("The Wind Turned The Pages", 1947).

Her three novels Dialogen fortsätter, 1932, Genomskådad, 1937, and Hemlighetsfull, 1938, are credited with projecting her pacifist stance foreseeing the threat of further war.

Her 1941 non-fiction title Väckarklocka (Alarm Clock) foresees environmental issues, but it was her biography of Selma Lagerlöf that is credited with winning her a place at the prestigious Swedish Academy.

[2] Wägner has recently been translated into English with Stockholm Stories (2002), which contains two of her wittiest novels: Men and Other Misfortunes and Stormy Corner.
