Rabbi Shmuel Bornsztain (born 1961), also spelled Borenstein or Bernstein, is the sixth Rebbe of the Sochatchov Hasidic dynasty. He acceded to the position of Rebbe following the sudden death of his father, Rabbi Menachem Shlomo Bornsztain, the fifth Rebbe of Sochatchov, in a traffic accident in Jerusalem. He was only eight years old at the time of the accident. Rabbi Shmuel continues to lead the Sochatchover dynasty from the Bayit VeGan neighborhood of Jerusalem, where the Sochatchov yeshiva, Yeshivat Avnei Nezer, is located.
