Harald Feller (1913–2003) was a Swiss diplomat who saved Hungarian Jews during the Holocaust, for which he was honored by Yad Vashem as one of the Righteous Among the Nations in 1999.
Feller worked closely with the other neutral legations in constantly pressuring the Horthy and Sztójay governments to end the persecution and deportations of Jews.
Feller protected members of the Swedish legation, who were targeted by the Arrow Cross Party, by giving them false Swiss passports and providing shelter.
Toward the end of the war, Feller hid dozens of Jews in the basement of his consular residence in Budapest.
In February 1945, the Soviets arrested Feller and Maximilian Jaeger and sent him to Moscow, along with other Swiss nationals.
