She made her debut for the senior national team on 19 February 2005 in a match against France. Her first goal came on 20 January 2006 in a match against China.
She was part of the squad for the 2007 Women's World Cup, playing in five matches, as well as the 2008 Summer Olympics held in Beijing, China, appearing in three matches. Knutsen also played in the 2005 European Championships, winning the silver medal after falling 3-1 to Germany in the finals.
On 21 October 2008 Marie Knutsen and four other Røa players -- Lene Mykjåland, Guro Knutsen, Marit Fiane Christensen and Siri Nordby—made headlines when they announced in a press release that they would not be returning to the national team due to issues the five had with the national team leadership. While the press statement never mentioned coach Bjarne Berntsen's name, it was assumed that he was instrumental in their decision to retire from the team. The retirement, which came off in many newspapers as a boycott, created widespread media attention.
Knutsen is a psychology student and was married in the summer of 2008. In January 2010 she announced she was expecting her first child and would not play football during 2010. She and her husband Patrick Johansen then moved to New York, USA where they live with their son Jasper. Her younger sister, Guro Knutsen still plays for Røa IL. She is a member of the Christian sports organization Kristen Idrettskontakt (KRIK).
