Avraham Eliezer Alperstein (c. 1853 – January 28, 1917) was an Orthodox Rabbi, Rosh yeshiva, publisher, communal leader and exceptional Talmudic scholar.

A few years later he accepted a position as rabbi of the Zevach Tzedek shul in the vibrant Jewish community of Slabodka.

The work boasted two notable approbations, one from the Beis HaLevi of Brisk and the other from Rabbi Jacob Joseph of New York.

Desiring to assist the yeshiva, Rabbi Alperstein's abilities as a dynamic public speaker in Yiddish proved useful as he campaigned throughout the Shteiblach of the Lower East Side for funds for RIETS.

Rabbi Alperstein was highly active in the areas of Kashrut and Jewish education.
