Wilhelm Przeczek (7 April 1936 in Karviná – 10 July 2006 in Třinec) was a Polish teacher, poet, writer, and activist from Zaolzie region of Cieszyn Silesia. He is considered one of the most important Polish writers of his generation from Zaolzie. During the Prague Spring of 1968, Przeczek supported the reformist wing of the Communist Party of Czechoslovakia. His stances led to ban of his works from 1969 to 1989 in Czechoslovakia. His books were therefore published mainly in Poland.
