Helge Iberg (born 27 March 1954 in Skien, Norway) is a Norwegian contemporary composer. Iberg studied musicology, history of ideas and religious studies at the University of Oslo under the tutorship of composers Olav Anton Thommessen and Ragnar Søderlind. 
As a composer, Iberg has made the transition from jazz to contemporary orchestral music. Iberg’s works have been commissioned and performed by several of Norway’s major symphony orchestras, the Norwegian Chamber Orchestra, Ultima Oslo Contemporary Music Festival and the Oslo Chamber Music Festival. 
Iberg is a recipient of a Prix Italia Work of the Year Award for his opera Det ondes problem (1990) as well as nominations to the Edvardprisen and the Spellemannprisen – the Norwegian equivalent to the Grammy. Iberg has composed concertos for pianist Christian Ihle Hadland, trumpeter Ole Edvard Antonsen as well as violinists Terje Tønnesen and Atle Sponberg. Iberg has also penned song cycles for vocalists Per Vollestad and Marianne Beate Kielland.
