Chaim Zanvl Abramowitz (Yiddish: חיים זאנוויל אבראמאוויטש, Hebrew: חיים זנוויל אברהמוביץ, born 1902 – died 18 October 1995), was known as the Ribnitzer Rebbe (ריבניצער רבי), and considered a great Hasidic tzadik from Rybnitsa (present-day Transnistria, Moldova). Others, including singer Mordechai Ben David, who was one of the rabbi's close disciples, maintain that he was born in 1893, making him 102 at the time of his passing. Abramowitz was a prominent follower of Rabbi Avrohom Matisyohu of Shtefanesht.
