Ketil Bjørnstad (born 25 April 1952 in Oslo) is a Norwegian pianist and composer. Initially trained as a classical pianist, Bjørnstad discovered jazz at an early age and has enthusiastically embraced the emergence of "European jazz".
Although perhaps best known as an artist on the ECM record label, Bjørnstad is also an accomplished writer, having published some 20 books (predominantly novels) and a number of poetry and essay collections.
