Jónína Leósdóttir (born 16 May 1954) is an Icelandic novelist, playwright and former journalist. She is the author of a dozen plays, seven novels, two biographies and a collection of articles she originally wrote for a women's magazine. She is married to the former Icelandic Prime Minister Jóhanna Sigurðardóttir, who was the first openly lesbian head of government in modern history. They were one of the first same-sex couples in Iceland to get married (in 2010, shortly after the law took effect, and while Jóhanna was in office); and until 2015, Jónína was the only modern person to have been the same-sex spouse of a sitting head of government (Belgium's Elio Di Rupo has never been married, while Luxembourg's Xavier Bettel was unable to legally marry until January 1, 2015). She has now written a book about her relationship with the former head of state. She has one son from a previous marriage. She has a BA in English and Literature from the University of Iceland.
