Jan Pietraszko (7 August 1911 - 2 March 1988) was a Polish Roman Catholic bishop who served as one of the auxiliaries for the Kraków archdiocese and Titular Bishop of Turrisblanda from 1962 until his death. Pietraszko was a noted spiritual director and chaplain as well as a popular confessor but was best known for his sermons and for his homiletic writings. He did his ecclesial studies just before World War II broke out and was a brief hostage of the Gestapo after the Nazi forces invaded Poland in 1939. He later came under the watch of the communist secret service following the conflict for his attempt to see new churches constructed and church art and architecture preserved.
