Zbigniew Karkowski (14 March 1958 – 12 December 2013) was a Polish experimental musician and composer.

During his education, he also attended many summer composition master courses arranged by Centre Acanthes in Avignon and Aix-en-Provence, France, studying with Iannis Xenakis, Olivier Messiaen, Pierre Boulez and Georges Aperghis, among others.

He wrote pieces for large orchestra (commissioned and performed by the Gothenburg Symphony Orchestra), plus an opera and several chamber music pieces that were performed by professional ensembles in Sweden, Poland, Switzerland and Germany.

Along with Edwin van der Heide and Atau Tanaka, he was a founding member of "Sensorband."

Karkowski lived and worked in Tokyo, Japan, for the last years of his life and was active in the underground noise scene there.
