Oswald Bosko (also spelled Bousko) was an Austrian policeman from Vienna later stationed at the Jewish ghetto of Kraków from 1942 to 1944.
He supported Julius Madritsch in rescuing Jews during World War II.
Bosko was posthumously honored by the State of Israel as a Righteous Among the Nations, meaning a non-Jew who risked his life during the Holocaust to save Jews from extermination by the Nazis.
