Many years a politician, she was previously Iceland's Minister of Social Affairs and Social Security from 1987–1994 and 2007–2009. She has been a member of the Althing (Iceland's parliament) for Reykjavík constituencies since 1978, winning re-election on eight successive occasions.

Jóhanna is a social democrat and Iceland's longest-serving member of Parliament. In the 1990s, when she lost a bid to head the party, she lifted her fist and declared "Minn tími mun koma!" ("My time will come!"), a phrase that became a popular Icelandic expression. In 2009, Forbes listed her among the 100 Most Powerful Women in the world
