Sochatchov is a Hasidic dynasty originating from the town of Sochaczew, Poland, where it was founded by Avrohom Bornsztain (1838–1910). Sochatchov is a branch of Kotzk Hasidism, which in part is a branch of Peshischa Hasidism. After World War I the dynasty was moved to Łódź and, subsequently, to other nearby towns. After World War II the dynasty was transplanted to Israel, where it thrives to this day.

Menachem Mendel Morgensztern of Kotzk, better known as the Kotzker Rebbe and the Kotzker (1787–1859) was a Hasidic rabbi and leader.
