Rav Mari ben Rav Dimi (Aramaic: רב מרי בר רב דימי; born mid-6th century) was the second Dean of Pumbedita Academy, succeeding Hanan of Iskiya. During Babylonian persecution of Pumbeditan Jewry, several notable scholars left to establish a Yeshiva academy in Firuz Shapur. Rav Mari served as the dean of this Yeshiva until the death of Hanan of Iskiya in 609, after which he was elected successor in the gaonate.[1]
