Aryeh Leib Malin (1906–1962) was a Polish-born American Haredi Jewish rabbi, Talmudic scholar, and Mussarist who taught the Torah and spread rabbinical education in Europe, China, Japan, and the United States.

As an older student, he was educated in the Mir Yeshiva of Belarus, where he gained a reputation as a prototype-follower of lomdus (in-depth study) and a model of mussar.

In Mir, Malin was part of an elite group of students who served as models of proper behavior and learning.

In 1941, in the midst of World War II, Malin declined an invitation to immigrate to the United States, extended to him by Rabbi Avraham Kalmanowitz.

On the last day of his life, he was seen in the women's section of the study hall, standing with his hands outstretched, deeply immersed in prayer.

Later, Malin collapsed after arriving late to a meeting in the house of Rabbi Shabsai Frankel (who famously re-printed the works of Maimonides).

Malin's main work, Chidushei Rebbi Aryeh Leib,[3] was published posthumously by his nephew Baruch Dov Povarsky.
