Menahem Mendel ben Meshullam Auerbach (1620 – July 8, 1689) (Hebrew: מנחם מענדל אויערבאך) was an Austrian rabbi, banker, and commentator born in Vienna at the beginning of the 17th century. He was descended from the well-known Auerbach-Fischhof family, both his father, Meshullam Solomon, and his maternal grandfather, Rabbi Judah Loeb Rofe, being members of the Vienna Ghetto.
