Shimon Yehuda Shkop (Hebrew: שמעון שקופ; 1860 – October 22, 1939) was a rosh yeshiva (dean) of the Yeshiva of Telshe (Telšiai) and then of Yeshiva Shaar HaTorah of Grodno, and a renowned Talmid Chacham (Talmudic scholar). He has created a unique way in classic Eastern European erudition, which is expressed mainly in his book Sha'arei Yosher, and is characterized by a logical-legal analysis of the basic principles of Halakha, and less than local pilpul.
