Bengt Hallberg (13 September 1932 – 2 July 2013) was a Swedish jazz pianist, composer and arranger. Born in Gothenburg, he studied classical piano from an early age, and wrote his first jazz arrangement at the age of 13. At the age of 15 he recorded his first record as a member of a group led by bassist Thore Jederby and in 1949 he recorded with the Swedish alto saxophonist Arne Domnérus for the first time, and the two musicians continued to play together for several decades. Hallberg died from congestive heart failure.
