Rabbi Yekusiel Yehuda Teitelbaum (1808–1883), known as the Yetev Lev (Hebrew: ייטב לב),[a] was a Hasidic Rebbe in Austria-Hungary.

After his studies, Yekusiel Yehuda, also known by his Yiddish equivalent names as Zalman Leib, was appointed as the rabbi of Stropkov (1833).

Yekusiel Yehuda Tetelbaum married Ruchl, a daughter of Rabbi Moshe Dovid Ashkenazi of Tolcsva and his wife.

Among the descendants of Yekusiel and Ruchl was their grandson Rabbi Joel Teitelbaum, the rebbe of Satmar, who emigrated to the United States after the Holocaust.

Reb Boruch of Gorlitz, son of the Divrei Chaim of Sanz, married one of their daughters.
