Rabbi Aharon Roth (אהרן ראטה‬, רבי אהרל'ה) known as Reb Arele (1894 − 1947), was a Hungarian Hasidic rebbe and Talmudic scholar. He first established a Ḥasidic community he called Shomer Emunim (Guardian of Faith) in the 1920s in Satu Mare and in the 1930s in Berehovo, before he settled in Jerusalem, where he also founded a Ḥasidic community of the same name.
