George Mantello (11 December 1901 – 25 April 1992) was a Jewish diplomat who, while working for the Salvadoran consulate in Geneva, Switzerland from 1942 to 1945, saved thousands of Jews from the Holocaust by providing them with fictive Salvadoran citizenship papers.
He publicized in mid-1944 the deportation of Hungarian Jews to the Auschwitz concentration camp, which had great impact on rescue and was a major contributing factor to Hungary's Regent Miklós Horthy stopping the transports to Auschwitz.
In recognition of his great contributions to rescue Mantello received an honorary doctorate from Yeshiva University.
Mantello is buried in the Jerusalem Har Hamenuchot cemetery.
