Bobov-45 (Hebrew: חסידות באבוב-45) is a Hasidic sect within Haredi Judaism. An offshoot of the Bobov Hasidic dynasty originating in Bobowa, Galicia, Southern Poland, Bobov-45 is headquartered in the neighborhood of Borough Park in Brooklyn, New York. It has branches in Williamsburg, Monsey, Lakewood, Montreal, Toronto, Antwerp and London. In Israel, Bobov-45 has branches in Jerusalem, Bnei Brak, Ashdod, Elad, the settlement of Betar Illit, and an enclave in Bat Yam named Kiryas Bobov.
Mordechai Dovid Unger is the first and current, Grand Rabbi of Bobov-45. He is the younger son-in-law of the fourth Bobover Rebbe, Naftali Zvi Halberstam. Yehoshua Rubin, the older son-in-law of Halberstam, is the current dayan and rabbinical leader of the sect.
The third Bobover Rebbe, Shlomo Halberstam, rebuilt the Bobov Hasidic dynasty in the United States after losing his wife and most of his children in the Holocaust. His son Naftali survived. The third rebbe remarried, and the union produced a son, Ben Zion Aryeh Leibish Halberstam, half brother to Naftali.
Naftali became the fourth rebbe upon his father's death. He had no sons, but left 2 daughters, one of whom married Mordechai Dovid Unger, and the other Yehoshua Rubin.
In 2005, after the death of the fourth rebbe, a breakaway group of Bobover Hasidim loyal to his son-in-law, Mordechai Dovid Unger, set up a grand hall under his leadership on 45th Street in Borough Park, Brooklyn. A leadership dispute then arose between Unger and Halberstam, who both claimed the title of Bobover Rebbe.
The dispute was taken to a beth din (arbitration panel), which ruled that the faction following Halberstam held the rights to the name "Bobov". Unger was also allowed to use the name Bobov, so long as a distinguishing identifier would be added to it. The qualifying suffix "-45" was henceforth adopted in tribute to the name of the street on which the community center of the sect was located at the time. In addition, the beth din ordered Bobov to pay $6,200,000 to Bobov-45's Rebbe and dayan (rabbinic judge) in 25 quarterly installments as an allotment of their faction's share of the inheritance of the Bobov enterprise's assets, valued at the time at over $50,000,000. The award was based upon the number of members in the two communities.
As Bobov-45 rebbe, Unger has also been active in the wider Jewish community.

In addition to those books revered by all Hasidim, the Bobov-45 Hasidim particularly treasure the teachings of the second Bobover Rebbe (published by the third Bobover Rebbe as Kedushas Tzion), and teachings of the third Bobover Rebbe Likutei Kerem Shlomo and Chochmas Shlomo (the latter published by Yechezkel Schlaff of London, affiliated with the court of Bobov-45).
