A maggid shiur (Hebrew: מגיד שיעור, romanized: maggiḏ shiʿur, lit. 'teller of a shiur or Torah lecture')^[1] is the rabbi that lectures in a yeshiva or kollel. He usually lectures in one place, on a given topic, generally on advanced and in-depth Talmudic studies, on a fixed schedule.

The stature of a maggid shiur is a much sought-after position by the typical yeshiva student. The position is usually obtained by those well versed in the Talmud.

Elazar Shach told a future maggid shiur that the key to successful lectures is "knowing how to ask the initial questions that comprise the shiur."^[2]
