Andrzej Krzanowski (9 April 1951 in Czechowice-Dziedzice – 1 October 1990 in Czechowice-Dziedzice) was a Polish composer of classical music, accordionist, and teacher.
Between 1971–75 Krzanowski studied with Henryk Górecki at the University of Music in Katowice.
He was an author of small and big chamber music forms scored for unconventional instruments, often in combination with a human voice or tape music, most often with the participation of the accordion. He was inspired by contemporary literature and he liked to use a quotation (Johann Sebastian Bach, Karol Szymanowski, Henryk Mikołaj Górecki). He was capable of creating an unusual climate with a considerable amount of expression ranging from spontaneous (Concerto for Orchestra) to lyrical and contemplative (Second Symphony, Third String Quartet).Audycja II WG Poezji (After Jacek Bieriezin); for reciter, flute, tam-tam, siren, whistle and 2 tapes, 1973
