Yehoshua Mondshine[1] (Hebrew: יהושע מונדשיין; 1947–2014) was an Israeli rabbi, scholar, researcher and historian associated with the Chabad-Lubavitch, Hasidic movement.

[2][3] Rabbi Mondshine authored over twenty works on Chabad Hasidic social and intellectual history,[2][4] and published a number of articles in various journals, both academic and rabbinic, some of them under the pseudonym Yehoshua D.

[5] Yoshua Mondshine was born on January 30, 1947 (or 9 Shevat, 5707, in the Hebrew calendar), in the city of Tel Aviv, Israel.

In around 1960, Mondshine began corresponding with the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, when he requested and received a blessing ahead of his Bar Mitzvah.

[4] Mondshine edited a number of books on the topic of Chabad history, referencing original manuscripts that he discovered, compiling evidence to differentiate between authoritative traditions and legends.

[8] Immanuel Etkes in turn cites Mondshine's identification with Chabad Hasidism as limiting the critical viewpoint necessary for such research.
