Stein Ingebrigtsen (born 23 August 1945) is a Norwegiansinger. He was enormously popular in Norway in the 1970s, nicknamed "Mr. Norsktoppen" for his countless hits topping Norsktoppen, an official chart for music in Norwegian.
From the 1960s and through the 1970s he sold more than one million albums, most of his songs being Norwegian translations of classics and famous pop songs of that period. Ingebrigtsen was heavily involved in the Treff-series ("Treff" being a direct Norwegian translation of "hit") which by 1978 finally comprised 21 discs consisting of translations of popular foreign songs. Among his hits were Norwegian versions of "Only You (and You Alone)" ("Bare du") and "It Never Rains in Southern California" ("Solen skinner der du aller helst vil være"). After this, Ingebrigtsen stepped down his own musical activity and only sporadic releases such as Stjernetegn and Soldatenes kortstokk in 1988 and 1989. He continued working as a producer for other musicians. Ingebrigtsen released Edelstein – de 20 beste in 2001.
