Jusztinián György Serédi OSB (23 April 1884 – 29 March 1945) was a Cardinal of the Roman Catholic Church and Archbishop of Esztergom and Prince Primate of Hungary.

Responding to the crisis, cardinal Serédi helped organize service for the refugees, ordering Hungarian Church officials to get actively involved in the religious and charitable services in the Polish refugee camps, among others he was instrumental in organizing a school and foster home for the Jewish children, eventually saved through the efforts of Henryk Sławik and his Polish and Hungarian associates.

[6] He considered the inauguration of Ferenc Szálasi illegal and refused to participate on his oath taking as the "Leader of the Nation".
