The Gjøvik Line (Norwegian: Gjøvikbanen) is a Norwegian railway line between Oslo and Gjøvik. It was originally named the North Line (Nordbanen) and ran between Grefsen and Røykenvik. The line was completed to Gjøvik in 1902. The Gjøvik Line was one of the first lines of the Norwegian railway system which was to be contracted on public service obligation, but it was the state owned Norges Statsbaner which won it through its subsidiary NSB Anbud.
