הרב מנחם מנדל קרוכמל היה רב ומנהיג בולט במזרח ומרכז אירופה. מפורסם על שם ספר השו"ת שלו, "צמח צדק".
Menahem Mendel ben Abraham Krochmal was a Moravian rabbi born in Kraków. His teacher in the Talmud was Joel Sirkes, author of Bayis Chadash. Krochmal soon distinguished himself so highly that with the permission of his master he was able to open a yeshiva, which sent forth scholars like Gershon Ashkenazi, and Menahem Mendel Auerbach, author of Ateres Zekeinim. The Jews of Cracow, in appreciation of his learning, made Krochmal dayan.
