Kehillas Yaakov Pupa (also "Puppa"; Hebrew/Yiddish: קהלת יעקב פאפא) is a Hasidic dynasty, named after the Yiddish name of the town of its origin (known in Hungarian as Pápa).
Before World War II Pupa had a yeshiva. The whole community was deported to the Auschwitz concentration camp, and only a few survived. There are no longer any Jews there.
The group is based in Williamsburg, Brooklyn, with branches in the Boro Park section of Brooklyn, Monsey, New York, Los Angeles, and Ossining, New York. It is headed by the Pupa rebbe, who has several thousand followers.
Pupa has more than 7,000 students enrolled in its yeshivas, girls schools, summer camps, and kollelim in Williamsburg, Boro Park, Monsey, Westchester County, New York, Montreal, Jerusalem, and elsewhere. In Williamsburg, Pupa is second in size to the Satmar Hasidim, with whom they share many communal facilities.
Kiryas Pupa is a village in Ossining, New York, established by Yosef Greenwald.[1] It includes the Kehilath Yakov Rabbinical Seminary, a 4-year school, and a cemetery.
More than 800 students are enrolled in the graduate yeshiva Gedolah, located on a pastoral 140-acre campus.
