Rabbi Yosef Engel (7 December 1858 - 25 October 1919 ) was an author of Torah scholarship and an Av Beit Din (chief rabbinical judge) in Kraków, Poland. He was known for his unique combination of creative conceptual thinking and vast breadth of knowledge of Rabbinic literature. Although only a fraction of his many writings have survived, several of them have become staples of contemporary Yeshiva learning.
