Sanz (or Tsanz, Yiddish: צאנז) is a Hasidic dynasty originating in the city of Sanz (Nowy Sącz) in Galicia. The dynasty was founded by the rebbe Rabbi Chaim Halberstam (1793–1876) who was the rabbi of Nowy Sącz and the author of the work Divrei Chaim by which name he is known as well. Rabbi Chaim was a disciple of Rabbi Naftali Zvi of Ropshitz. He opened his court after the death of Rabbi Asher Yeshaya of Ropshitz, son-in-law of Rabbi Naftali Tzvi.
