Rabbi Yaakov Yehuda Aryeh Leib Frenkel יעקב יהודה אריה ליב פרענקיל (died June 12, 1940) also known as the Gevuras Aryeh after his major work, was Rabbi of Piricse and a renowned Kabbalist.

Rabbi Frenkel's year of birth is variously cited as 1850[1] or 1855.

When Rabbi Frenkel matured and needed to earn a livelihood, he assumed a teaching position in Spinka, upon the recommendation of Rabbi Teitelbaum.

[4] When Rabbi Frenkel retired, he moved to Satmar (Satu Mare) in Romania, where he was regarded as a rabbinical authority.

Although Rabbi Frenkel authored numerous works due to financial difficulties, only five books were ever published.
