Elín Rannveig Briem née Eiriksdóttir (1856–1937) was an Icelandic teacher and writer who in 1889 published one of Iceland's most popular books, Kvennafræðarinn (The Women's Instructor).
Principally a cookbook, it also provided advice to housewives on health, hygiene and economics.
The work was based on the classes she gave to her students while headmistress of the girls college at Ytri-Ey near Skagaströnd in the north of Iceland.
