The Vålerenga Line (Norwegian: Vålerengalinjen), also known as Helsfyr Line and Etterstad Line, is an abandoned line of the Oslo Tramway of Norway. It branched from the Gamlebyen Line in Schweigaards gate and ran into the neighborhoods of Vålerenga, Etterstad and Helsfyr. The line followed the streets of Schweigaards gate, St. Halvars gate, Enebakkveien, one direction each in Vålerenggata and Strømsveien, and Etterstadgata. The line continued as a suburban light rail as the Østensjø Line and the Lambertseter Line.
