Melchior Hoffman (or Hofmann c. 1495 – c. 1543) was a German Anabaptist, radical lay preacher and reformer in northern Europe. He began his career as an outspoken proponent of Lutheranism but evolved his own theological voice influenced by late medieval mysticism, Joachimite apocalypticism, and the Anabaptist movement. He is credited with introducing Anabaptism to the Low Countries.
