The Norwegian Football Cup (Norwegian: Norgesmesterskapet i fotball for herrer) is the main knockout cup competition in Norwegian football. It is run by the Football Association of Norway and has been contested since 1902, making it the oldest football tournament in the country. The tournament is commonly known as Cupen ("The Cup") or NM, an acronym formed from Norgesmesterskap ("Norwegian Championship"). These terms are used to describe both the men's and women's competitions. The equivalent competition for women's teams is the Norwegian Women's Football Cup.
The Norwegian Football Cup is a national championship, meaning that while the Norwegian Premier League may be the most prestigious competition to win, it is the winners of the Cup who are awarded the title "Norwegian football champions". This differs from, for example, English football, where the winners of the FA Premier League are the ones who become English champions.
The current Norwegian champions and holders of the cup are Rosenborg, who defeated Sarpsborg 08 2–0 in the 2015 final.
