Antoni Baraniak (1 January 1904 – 13 August 1977) was a Polish Roman Catholic prelate and professed member from the Salesians of Don Bosco who served as the Archbishop of Poznan from mid-1957 until his death.
Baraniak studied in Poland and in Rome prior to his ordination and served as the private aide to Cardinals August Hlond and Stefan Wyszynski; he was devoted to both men and served with both during World War II and the increasing communist repression.
He served as a bishop in Gniezno before being appointed as an archbishop though just prior to that was arrested.
The communist authorities interrogated and tortured Baraniak while he was imprisoned but remained silent and refused to tell his captors about the activities of prelates.Baraniak's life has caused calls for his beatification to be made and it has been decided that the cause will be requested and then launched if it is approved.
