Ben Zion Aryeh Leibish Halberstam

Ben Zion Aryeh Leibish Halberstam (; born 1955) is an American born Hasidic rabbi. He is the current Rebbe of the Bobov Hasidic dynasty. Appointed in 2005, Halberstam has a direct lineage to the founder of the Bobov Hasidic dynasty.

Early life Ben Zion Aryeh Leibish Halberstam was born to the third Bobover rebbe Shlomo Halberstam and his second wife. His father had lost his first wife and most of their children in the Holocaust, but a son, Naftali, survived. Naftali was later reunited with the family in Borough Park, Brooklyn.

Appointment Right after his father's passing in 2000, Naftali was appointed as fourth Bobover Rebbe at age 69. Naftali died right before the Purim holiday in 2005, which led to a succession crisis over who should be the Grand Rebbe of the many Bobov Hasidim worldwide. When a vote failed to solve the matter the battle of succession was brought before a beth din (religious court) in 2007, which ultimately ruled that Halberstam would be declared the fifth Rebbe of Bobov with its headquarters on 48th Street in Borough Park, while Unger can choose the title Rebbe of Bobov-45 , located on 45th Street.

Career In 2014, Halberstam launched Kinyan Torah, a program to encourage laymen to learn Talmud. Those enrolled in the program were able to take the monthly test and those who scored an 80 or above earned a stipend. The program was expanded to include young children in 2023. At times over a thousand test takers were recorded.

In 2021, he launched a $125 million campaign to build new schools for the elementary boys and girl school.

As of 2024, Bobov has satellite communities in Monsey; Toronto; Lakewood NJ; Linden NJ; London; Montreal; Antwerp; and Williamsburg NY; in addition to many locations in Israel.
