Bjørn G. Gjerstrøm (born in Oslo in 1939, deceased 8 May 2017) was a Norwegian contemporary composer.
From an early age, Gjerstrøm would receive musical impulses from his parents, the composer Gunnar Gjerstrøm and music teacher Elsa Gjerstrøm. His mother began teaching him on the piano from the age of 4-5. He completed his first composition at the age of 9. At the age of twelve, his first compositions, 5 piano pieces that he performed on Norwegian and Swedish radio, were published by Norsk Notestikk and Forlag.

In the 60s, Gjerstrøm studied with Trygve Lindeman and Conrad Baden at the Music Conservatory in Oslo, where he followed classes in music theory, harmony and composition. He also studied piano with Waldemar Alme and Ivar Johnsen. From 1969 to 1976 he studied composition with Hallvard Johnsen. 
Gjerstrøm’s list of works encompasses film scores, orchestral works, chamber music as well as solo pieces for flute, oboe, guitar and accordion. Gjerstrøm has also penned songs for poems by Peter R. Holm, Stein Mehren, Arnulf Øverland and Elsa Gjerstrøm.

Key Gjerstrøm works includes Concerto for piano and orchestra Op.7, premiered in 1983 by pianist Kjell Bækkelund and the Oslo Philharmonic Orchestra with conductor Per Dreier. The Stavanger Symphony Orchestra has performed the work on later occasions in Stavanger and Bergen. With composer Greta Jordhøy, Gjerstrøm has performed on a number of occasions with his own works at venues in Oslo and Heggedal.
